• UCM 11g is 4 days old!

  - by kyle.hatlestad

  Ok...so I missed posting a blog entry when UCM 11g and the entire ECM suite released on Tuesday. Hopefully you've already seen the announcements on any number of the Oracle ECM blogs out there such as ECM Alerts, Fusion ECM, bex huff, or C4. So I won't bore you with the same talking points like 179 million check-ins per day or 124 web site page hits per second. Instead, I thought I'd show some screenshots of the new features in UCM and URM 11g. WebLogic Server and Enterprise Manager So probably the biggest change in 11g is UCM and URM now run on top of the WebLogic Server application server. This is a huge step as ECM is now on a standard platform with the rest of Oracle Fusion Middleware which makes installation, configuration, and integration consistent among all the products. From a feature perspective, it's also beneficial because it's now integrated with Oracle Enterprise Manager. Enterprise Manager provides a lot of provisioning control over servers as well as performance monitoring and access to logs and debugging information. Desktop Integration Suite Desktop Integration Suite got a complete overhaul for 11g. It exposes a lot more features within Windows Explorer such as saved searches, workflow queue, and checked-out items. It also now support metadata pop-up screens to let users fill in additional metadata when they drag-n-drop files in! And the integration within Office applications has changed significantly by introducing a dedicated UCM menu to do open, save, compare, etc. Site Studio for External Applications In UCM Site Studio 10gR4, a major architectural shift was introduced which brought several new objects such as elements, region definitions, region templates, and placeholder definitions. This truly separated the content from the display and from the definition. It also allowed separation of the content from needing to be rendered on a complete Site Studio page. Well, the new Site Studio for External Applications takes advantage of that architecture and introduces pre-built tags and plug-ins to JDeveloper to allow to go from simply adding a content area to your web application page to building an entire web site, just like you would have done in Site Studio Designer. In addition to these changes, enhancements to the core Site Studio have been added as well. One of the big ones is called Designer Mode which allows power-users to bypass the standard rules defined by the placeholder definition or template and perform any number of additional actions. This reduces the need to go back to Site Studio Designer or JDeveloper to make more advanced changes to the site. Dashboards As part of the updated records management functionality in both UCM and URM, users can now set a dashboard view on their home page to surface common functions in a single view. It has pre-built "portlets" users can choose from to display and organize they way they want. Behind the scenes, these dashboards are stored as Content Folios. So the dashboards themselves are content items that can be revisioned and shared between users. And new dashboard portlets can be easily added (like the User Profile one in the screenshots) by getting a copy of an existing one, modifying the display, and then checking it in as a new one to select from. URM Interface Enhancements URM includes several new UI and usability enhancements in 11g. There is a new view for physical records, a place to configure "favorite" items to quickly get to, and new placement of the records management menu. BI Publisher Reports Records management in UCM and URM now offer reports generated through embedded BI Publisher. Templates are controlled by rich text files checked directly into the repository, so they can be easily modified. Other Features A new Inbound Refinery conversion option is available that does native Microsoft Office HTML conversion. If your IBR is on Windows and you have the native applications loaded, the IBR can use them to produce HTML. A new GUI template editor for Dynamic Converter is available. It's written in Java so is available through all the supported browsers and platforms. The original ActiveX based editor is also still available. The Component Manager interface has changed to help provide an easier and more descriptive way to enable core components that are installed along with UCM. All of the supported components are immediately available to turn on and do not have to be installed separately as in previous versions. My Downloads is located in the My Content Server menu and provides for easy download of client installs including Desktop Integration Suite and Site Studio Designer. Well, hopefully that gives you a taste for some of the new things in 11g. We're all pretty excited here at Oracle about all the new changes and enhancements. Over the next few months I hope to highlight some of these features more in-depth, so keep your eye out for those posts.

• How to Modify Data Security in Fusion Applications

  - by Elie Wazen

  The reference implementation in Fusion Applications is designed with built-in data security on business objects that implement the most common business practices.  For example, the “Sales Representative” job has the following two data security rules implemented on an “Opportunity” to restrict the list of Opportunities that are visible to an Sales Representative: Can view all the Opportunities where they are a member of the Opportunity Team Can view all the Opportunities where they are a resource of a territory in the Opportunity territory team While the above conditions may represent the most common access requirements of an Opportunity, some customers may have additional access constraints. This blog post explains: How to discover the data security implemented in Fusion Applications. How to customize data security Illustrative example. a.) How to discover seeded data security definitions The Security Reference Manuals explain the Function and Data Security implemented on each job role.  Security Reference Manuals are available on Oracle Enterprise Repository for Oracle Fusion Applications. The following is a snap shot of the security documented for the “Sales Representative” Job. The two data security policies define the list of Opportunities a Sales Representative can view. Here is a sample of data security policies on an Opportunity. Business Object Policy Description Policy Store Implementation Opportunity A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team Role: Opportunity Territory Resource Duty Privilege: View Opportunity (Data) Resource: Opportunity A Sales Representative can view opportunity where they are an opportunity sales team member with view, edit, or full access Role: Opportunity Sales Representative Duty Privilege: View Opportunity (Data) Resource: Opportunity Description of Columns Column Name Description Policy Description Explains the data filters that are implemented as a SQL Where Clause in a Data Security Grant Policy Store Implementation Provides the implementation details of the Data Security Grant for this policy. In this example the Opportunities listed for a “Sales Representative” job role are derived from a combination of two grants defined on two separate duty roles at are inherited by the Sales Representative job role. b.) How to customize data security Requirement 1: Opportunities should be viewed only by members of the opportunity team and not by all the members of all the territories on the opportunity. Solution: Remove the role “Opportunity Territory Resource Duty” from the hierarchy of the “Sales Representative” job role. Best Practice: Do not modify the seeded role hierarchy. Create a custom “Sales Representative” job role and build the role hierarchy with the seeded duty roles. Requirement 2: Opportunities must be more restrictive based on a custom attribute that identifies if a Opportunity is confidential or not. Confidential Opportunities must be visible only the owner of the Opportunity. Solution: Modify the (2) data security policy in the above example as follows: A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team and the opportunity is not confidential. Implementation of this policy is more invasive. The seeded SQL where clause of the data security grant on “Opportunity Territory Resource Duty” has to be modified and the condition that checks for the confidential flag must be added. Best Practice: Do not modify the seeded grant. Create a new grant with the modified condition. End Date the seeded grant. c.) Illustrative Example (Implementing Requirement 2) A data security policy contains the following components: Role Object Instance Set Action Of the above four components, the Role and Instance Set are the only components that are customizable. Object and Actions for that object are seed data and cannot be modified. To customize a seeded policy, “A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team”, Find the seeded policy Identify the Role, Object, Instance Set and Action components of the policy Create a new custom instance set based on the seeded instance set. End Date the seeded policies Create a new data security policy with custom instance set c-1: Find the seeded policy Step 1: 1. Find the Role 2. Open 3. Find Policies Step 2: Click on the Data Security Tab Sort by “Resource Name” Find all the policies with the “Condition” as “where they are a territory resource in the opportunity territory team” In this example, we can see there are 5 policies for “Opportunity Territory Resource Duty” on Opportunity object. Step 3: Now that we know the policy details, we need to create new instance set with the custom condition. All instance sets are linked to the object. Find the object using global search option. Open it and click on “condition” tab Sort by Display name Find the Instance set Edit the instance set and copy the “SQL Predicate” to a notepad. Create a new instance set with the modified SQL Predicate from above by clicking on the icon as shown below. Step 4: End date the seeded data security policies on the duty role and create new policies with your custom instance set. Repeat the navigation in step Edit each of the 5 policies and end date them 3. Create new custom policies with the same information as the seeded policies in the “General Information”, “Roles” and “Action” tabs. 4. In the “Rules” tab, please pick the new instance set that was created in Step 3.

• Feedback on "market manipulation", a peripheral game mechanic for a satirical MMO

  - by BerndBrot

  This question asks for feedback on a specific game-mechanic. Since there is not one right feedback on a game mechanic, I tried to provide enough context and guidelines to still make it possible for users to rate answers and to accept an answer as the best answer (following these criteria from Writer.SE's meta website). Please comment if you have any suggestions on how I could improve the question in that regard. So, let's begin with the game itself and some of its elements which are relevant for this question. Context I'm working on a satirical, text-based multiplayer adventure and role-playing game set in modern-day London. The game resolves around the concept of sin and features a myriad of (venomous) allusions to all the things that go wrong in this world. Players can choose between character classes like bullshit artist (consultant), bankster, lawyer, mobster, celebrity, politician, etc. In order to complete the game, the player has to live so sinfully with regard to any of the seven deadly sins that a demon is willing to offer them a contract of sponsorship. On their quest to live a sinful live, characters explore more and more locations of modern-day London (on a GoogleMap), fight "monsters" like insurance sales agents or Jehovah's Witnesses, and complete quests, like building a PowerPoint presentation out of marketing buzz words or keeping up a number of substance abuse effects in order to progress on the gluttony path. Battles are turn based with both combatants having a deck of cards, with which they try to make their enemy give in to temptations of all sorts. Tempted enemies sometimes become contacts (an item drop mechanic), which can be exploited for various benefits, depending on their area of influence (finance, underworld, bureaucracy, etc.), level of influence, and kind of sway that the player has over them (bribed, seduced, threatened, etc.) Once a contract has been exploited, the player loses that contact. Most actions require turns. Turns are limited, but refill each day. Criteria A number of peripheral game mechanics are supposed to represent real world abuses and mischief in a humorous way integrate real world data and events to strengthen the feeling of relevance of the game's humor with regard to real world problems add fun ways of interacting with other players add ways for players to express themselves through game-play Market manipulation is one such peripheral game mechanic and should fulfill all of these goals. Market manipulation This is my initial design of the mechanic: Players can enter the London Stock Exchange (LSE) (without paying a turn) LSE displays the stock prices of a number of companies in industries like weapons or tobacco as well as some derivatives based on wheat and corn. The stock prices are calculated based on the actual stock prices of these companies and derivatives (in real time) any market manipulations that were conducted by the players any market corrections of the system Players can buy and sell shares with cash, a resource in the game, at current in-game market value (without paying a turn). Players can manipulate the market, i.e. let the price of a share either rise or fall, by some amount, over a certain period of time. Manipulating the market requires 1 turn A contact in the financial sector (see above). The higher the level of influence of the contact, the stronger the effect of the manipulation on the stock price, and/or the shorter it takes for the manipulation to manifest itself. Market manipulation also adds a crime to the player's record. (There are a multitude of ways to take care of that, but it is still another "cost" of market manipulations.) The system continuously corrects market manipulations by letting the in-game prices converge towards their real world counterparts at a rate of 2% of the difference between the two per hour. Because of this market correction mechanism, pushing up prices (and screwing down prices) becomes increasingly difficult the higher (lower) the price already is. Whenever food prices reach a certain level, in-game stories are posted about hunger catastrophes happening somewhere far, far away (maybe with links to real world news stories). Whenever a player sells a certain number of shares with a sufficiently high margin, they are mentioned in that day's in-game financial news. Since the number of stock options is very limited, players will inevitably collide in their efforts to manipulate the market in their favor. Hopefully, it will also be a fun side-arena for guilds and covenants to fight each other. Question(s) What do you think of this mechanism given the criteria for peripheral game mechanics that I specified for my game? Do you have any ideas how the mechanic could be improved with regard to these criteria (or otherwise)? Could it be improved to allow for more expressive game-play, or involve an allusion to some other real world madness (like short selling, leveraging, or some other banking magic)? Are there any game-theoretic problems with this mechanic, like maybe certain dominant individual strategies that, collectively, lead to every player profiting and thus eliminating the idea of market manipulation PVP? Also, if you like (or dislike) this question, feel free to participate in the discussion on GDSE meta: "Should we be more lax with regard to SE's question/answer format to make game design questions possible?"

• It’s nice to be important, but it’s more important to be nice

  - by BuckWoody

  I’ve been a little “preachy” lately, telling you that you should let people finish their sentences, and always check a problem out before you tell a user that their issue is “impossible”. Well, I’ll round that out with one more tip today. Keep in mind that all of these things are actions I’ve been guilty of, hopefully in the past. I’m kind of a “work in progress”. And yes, I know these tips are coming from someone who picks on people in presentations, but that is of course done in fun, and (hopefully) with the audience’s knowledge.   (No, this isn’t aimed at any one person or event in particular – I just see it happen a lot)   I’ve seen, unfortunately over and over, someone in authority react badly to someone who is incorrect, or at least perceived to be incorrect. This might manifest itself in a comment, post, question or whatever, but the point is that I’ve seen really intelligent people literally attack someone they view as getting something wrong. Don’t misunderstand me; if someone posts that you should always drop a production database in the middle of the day I think you should certainly speak up and mention that this might be a bad idea!  No, I’m talking about generalizations or even incorrect statements done in good faith. Let me explain with an example.   Suppose someone makes the statement: “If you don’t have enough space on your system, you can just use a DBCC command to shrink the database”. Let’s take two responses to this statement.   Response One: “That’s insane. Everyone knows that shrinking a database is a stupid idea, you’re just going to fragment your indexes all over the place.” Response Two: “That’s an interesting take – in my experience and from what I’ve read here (someurl.com) I think this might not be a universal best practice.”   Of course, both responses let the person making the statement and those reading it know that you don’t agree, and that it’s probably wrong. But the person you responded to and the general audience hearing you (or reading your response) might form two different opinions of you.   The first response says to me “this person really needs to be right, and takes arguments personally. They aren’t thinking of the other person at all, or the folks reading or hearing the exchange. They turned an incorrect technical statement into a personal attack. They haven’t left the other party any room to ‘save face’, and they have potentially turned what could be a positive learning experience for everyone into a negative. Also, they sound more than just a little arrogant.”   The second response says to me “this person has left room for everyone to save face, has presented evidence to the contrary and is thinking about moving the ball forward and getting it right rather than attacking someone for getting it wrong.” It’s the idea of questioning a statement rather than attacking a person.   Perhaps you have a different take. Maybe you think the “direct” approach is best – and maybe that’s worked for you. Something to consider is what you’ve really accomplished while using that first method. Sure, the info you provide is correct, and perhaps someone out there won’t shrink a database because of your response – but perhaps you’ve turned a lot more people off, and now they won’t listen to your other valuable information. You’ll be an expert, but another one of the nameless, arrogant jerks in technology. And I don’t think anyone likes to be thought of that way.   OK, I’ll get down off of the high-horse now. And I’ll keep the title of this entry (said to me by my grandmother when I was a little kid) in mind when I dismount.

• Your thoughts on Best Practices for Scientific Computing?

  - by John Smith

  A recent paper by Wilson et al (2014) pointed out 24 Best Practices for scientific programming. It's worth to have a look. I would like to hear opinions about these points from experienced programmers in scientific data analysis. Do you think these advices are helpful and practical? Or are they good only in an ideal world? Wilson G, Aruliah DA, Brown CT, Chue Hong NP, Davis M, Guy RT, Haddock SHD, Huff KD, Mitchell IM, Plumbley MD, Waugh B, White EP, Wilson P (2014) Best Practices for Scientific Computing. PLoS Biol 12:e1001745. http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.1001745 Box 1. Summary of Best Practices Write programs for people, not computers. (a) A program should not require its readers to hold more than a handful of facts in memory at once. (b) Make names consistent, distinctive, and meaningful. (c) Make code style and formatting consistent. Let the computer do the work. (a) Make the computer repeat tasks. (b) Save recent commands in a file for re-use. (c) Use a build tool to automate workflows. Make incremental changes. (a) Work in small steps with frequent feedback and course correction. (b) Use a version control system. (c) Put everything that has been created manually in version control. Don’t repeat yourself (or others). (a) Every piece of data must have a single authoritative representation in the system. (b) Modularize code rather than copying and pasting. (c) Re-use code instead of rewriting it. Plan for mistakes. (a) Add assertions to programs to check their operation. (b) Use an off-the-shelf unit testing library. (c) Turn bugs into test cases. (d) Use a symbolic debugger. Optimize software only after it works correctly. (a) Use a profiler to identify bottlenecks. (b) Write code in the highest-level language possible. Document design and purpose, not mechanics. (a) Document interfaces and reasons, not implementations. (b) Refactor code in preference to explaining how it works. (c) Embed the documentation for a piece of software in that software. Collaborate. (a) Use pre-merge code reviews. (b) Use pair programming when bringing someone new up to speed and when tackling particularly tricky problems. (c) Use an issue tracking tool. I'm relatively new to serious programming for scientific data analysis. When I tried to write code for pilot analyses of some of my data last year, I encountered tremendous amount of bugs both in my code and data. Bugs and errors had been around me all the time, but this time it was somewhat overwhelming. I managed to crunch the numbers at last, but I thought I couldn't put up with this mess any longer. Some actions must be taken. Without a sophisticated guide like the article above, I started to adopt "defensive style" of programming since then. A book titled "The Art of Readable Code" helped me a lot. I deployed meticulous input validations or assertions for every function, renamed a lot of variables and functions for better readability, and extracted many subroutines as reusable functions. Recently, I introduced Git and SourceTree for version control. At the moment, because my co-workers are much more reluctant about these issues, the collaboration practices (8a,b,c) have not been introduced. Actually, as the authors admitted, because all of these practices take some amount of time and effort to introduce, it may be generally hard to persuade your reluctant collaborators to comply them. I think I'm asking your opinions because I still suffer from many bugs despite all my effort on many of these practices. Bug fix may be, or should be, faster than before, but I couldn't really measure the improvement. Moreover, much of my time has been invested on defence, meaning that I haven't actually done much data analysis (offence) these days. Where is the point I should stop at in terms of productivity? I've already deployed: 1a,b,c, 2a, 3a,b,c, 4b,c, 5a,d, 6a,b, 7a,7b I'm about to have a go at: 5b,c Not yet: 2b,c, 4a, 7c, 8a,b,c (I could not really see the advantage of using GNU make (2c) for my purpose. Could anyone tell me how it helps my work with MATLAB?)

• Figuring out the IIS Version for a given OS in .NET Code

  - by Rick Strahl

  Here's an odd requirement: I need to figure out what version of IIS is available on a given machine in order to take specific configuration actions when installing an IIS based application. I build several configuration tools for application configuration and installation and depending on which version of IIS is available on IIS different configuration paths are taken. For example, when dealing with XP machine you can't set up an Application Pool for an application because XP (IIS 5.1) didn't support Application pools. Configuring 32 and 64 bit settings are easy in IIS 7 but this didn't work in prior versions and so on. Along the same lines I saw a question on the AspInsiders list today, regarding a similar issue where somebody needed to know the IIS version as part of an ASP.NET application prior to when the Request object is available. So it's useful to know which version of IIS you can possibly expect. This should be easy right? But it turns there's no real easy way to detect IIS on a machine. There's no registry key that gives you the full version number - you can detect installation but not which version is installed. The easiest way: Request.ServerVariables["SERVER_SOFTWARE"] The easiest way to determine IIS version number is if you are already running inside of ASP.NET and you are inside of an ASP.NET request. You can look at Request.ServerVariables["SERVER_SOFTWARE"] to get a string like Microsoft-IIS/7.5 returned to you. It's a cinch to parse this to retrieve the version number. This works in the limited scenario where you need to know the version number inside of a running ASP.NET application. Unfortunately this is not a likely use case, since most times when you need to know a specific version of IIS when you are configuring or installing your application. The messy way: Match Windows OS Versions to IIS Versions Since Version 5.x of IIS versions of IIS have always been tied very closely to the Operating System. Meaning the only way to get a specific version of IIS was through the OS - you couldn't install another version of IIS on the given OS. Microsoft has a page that describes the OS version to IIS version relationship here: http://support.microsoft.com/kb/224609 In .NET you can then sniff the OS version and based on that return the IIS version. The following is a small utility function that accomplishes the task of returning an IIS version number for a given OS: /// <summary> /// Returns the IIS version for the given Operating System. /// Note this routine doesn't check to see if IIS is installed /// it just returns the version of IIS that should run on the OS. /// /// Returns the value from Request.ServerVariables["Server_Software"] /// if available. Otherwise uses OS sniffing to determine OS version /// and returns IIS version instead. /// </summary> /// <returns>version number or -1 </returns> public static decimal GetIisVersion() { // if running inside of IIS parse the SERVER_SOFTWARE key // This would be most reliable if (HttpContext.Current != null && HttpContext.Current.Request != null) { string os = HttpContext.Current.Request.ServerVariables["SERVER_SOFTWARE"]; if (!string.IsNullOrEmpty(os)) { //Microsoft-IIS/7.5 int dash = os.LastIndexOf("/"); if (dash > 0) { decimal iisVer = 0M; if (Decimal.TryParse(os.Substring(dash + 1), out iisVer)) return iisVer; } } } decimal osVer = (decimal) Environment.OSVersion.Version.Major + ((decimal) Environment.OSVersion.Version.MajorRevision / 10); // Windows 7 and Win2008 R2 if (osVer == 6.1M) return 7.5M; // Windows Vista and Windows 2008 else if (osVer == 6.0M) return 7.0M; // Windows 2003 and XP 64 bit else if (osVer == 5.2M) return 6.0M; // Windows XP else if (osVer == 5.1M) return 5.1M; // Windows 2000 else if (osVer == 5.0M) return 5.0M; // error result return -1M; } } Talk about a brute force apporach, but it works. This code goes only back to IIS 5 - anything before that is not something you possibly would want to have running. :-) Note that this is updated through Windows 7/Windows Server 2008 R2. Later versions will need to be added as needed.

• Cost justification for buying a 32GB superfast Alienware M18x with a price tag of around £5K ($10K)

  - by tonyrogerson

  When considering buying a laptop that’s going to cost me around £5,000 I really need to justify the purchase from a business perspective; my Lenovo W700 has served me very well for the last 2 years, it’s an extremely good machine and as solid as a rock (and as heavy), alas though it is limited to the 8GB. As SQL Server 2012 approaches and with my interest in working in the Business Intelligence space over the next year or two it is clear I need a powerful machine that I can run a full infrastructure though virtualised. My requirements For High Availability / Disaster Recovery research and demonstration Machine for a domain controller Four machines in a shared disk cluster (SQL Server Clustering active – active etc.) Five  machines in a file share cluster (SQL Server Availability Groups) For Business Intelligence research and demonstration Not entirely sure how many machine I want to run here, but it would be to cover the entire BI stack in an enterprise setting, sharepoint, sql server etc. For Big Data Research I have a fondness for the NoSQL approach to scalability and dealing with large volumes so I need a number of machines to research VoltDB, Hadoop etc. As you can see the requirements for a SQL Server consultant to service their clients well is considerable; will 8GB suffice, alas no, it will no longer do. I’m a very strong believer that in order to do your job well you must expense it, short cuts only cost you time, waiting 5 minutes instead of an hour for something to run not only saves me time but my clients time, I can do things quicker and more importantly I can demonstrate concepts. My W700 with the 8GB of RAM and SSD’s cost me around £3.5K two years ago, to be honest I’ve not got the full use I wanted out of it but the machine has had the power when I’ve needed it, it’s served me and my clients well. Alienware now do a model (the M18x) with 32GB of RAM; yes 32GB in a laptop! Dual drives so I can whack a couple of really good SSD’s in there, a quad core with hyper threading i7 and a decent speed. I can reduce the cost of the memory by getting it from Crucial, so instead of £1.5K for 32GB it will be around £900, I can also cost save on the SSD as well. The beauty about the M18x is that it is USB3.0, SATA 3 and also really importantly has eSATA, running VM’s will never be easier, I can have a removeable SSD with my VM’s on it and can plug it into my home machine or laptop – an ideal world! The initial outlay of £5K is peanuts compared to the benefits I’ll give my clients, I will be able to present real enterprise concepts, I’ll also be able to give training on those real enterprise concepts and with real, albeit virtualised machines.

• Record and Play your WebLogic Console Tasks Like a DVR

  - by james.bayer

  Automation using WebLogic Scripting Tool Today on the Oracle internal mailing list for WebLogic Server questions someone asked how to automate the configuration of the thread model for WebLogic Server and they were having trouble with the jython scripting syntax.  I’ve previously written about this feature called Work Managers and the associated constraints.  However, I did not show how to automate the process of configuring this without the console using WebLogic Scripting Tool – the jython scripting automation environment abbreviated as WLST.  I’ve written some very basic introductions to WLST before and there is also an Oracle By Example on the subject, but this is a bit more advanced.  Fear not because there is a really easy-to-use feature of the WLS console that lets you “Record” user actions just like a DVR.  Using these recordings of the web-based console, you can easily create a script even if you are unfamiliar with the WLST syntax and API.  I’m a big fan of both DVR’s and automation as can be evidenced with this old Halloween picture taken during simpler times.  Obviously the Cast Away and The Big Labowski references show some age.  I was a big Tivo fan-boy back in the day and I still think it’s the best DVR. I strongly believe that WebLogic Scripting Tool (WLST) is an absolutely essential tool for automating administration tasks in anything beyond a development environment.  Even in development environments you can make a case that it makes sense to start the automation for environments downstream.  I promise you that once you start using it for any tasks that you do even semi-regularly, you won’t go back to clicking through the console.  It’s simply so much more efficient and less error-prone to run a script. Let’s say you need to create a Work Manager and MaxThreadsConstraint – the easy way to do it is configure it in the WLS console first while capturing the commands with a recording.  See the images for the simple steps – click to enlarge. Record Console Configurations to a File Review the Recordings and Make Slight Modifications In order to make the recorded .py file directly callable as a stand-alone script I added calls to the connect() and edit() functions at the beginning and calls to disconnect() and exit() at the end – otherwise the main section of the script was provided by the console recording.  Below is the resulting file I saved as d:/temp/wm.py connect('weblogic','welcome1', 't3://localhost:7001') edit() startEdit()   cd('/SelfTuning/wl_server') cmo.createMaxThreadsConstraint('MaxThreadsConstraint-0')   cd('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName)) cmo.setCount(5) cmo.unSet('ConnectionPoolName')   cd('/SelfTuning/wl_server') cmo.createWorkManager('WorkManager-0') cd('/SelfTuning/wl_server/WorkManagers/WorkManager-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName))   cmo.setMaxThreadsConstraint(getMBean('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0')) cmo.setIgnoreStuckThreads(false)   activate() disconnect() exit() Run the Script If you want to test it be sure to delete the Work Manager and MaxThreadConstraint that you had previously created in the console.  Do something like the following - set up the environment and tell WLST to execute the script which happens in the first 2 lines, the rest doesn’t require any user input: D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server\bin>setDomainEnv.cmd D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server>java weblogic.WLST d:\temp\wm.py   Initializing WebLogic Scripting Tool (WLST) ...   Welcome to WebLogic Server Administration Scripting Shell   Type help() for help on available commands   Connecting to t3://localhost:7001 with userid weblogic ... Successfully connected to Admin Server 'examplesServer' that belongs to domain 'wl_server'.   Warning: An insecure protocol was used to connect to the server. To ensure on-the-wire security, the SSL port or Admin port should be used instead.   Location changed to edit tree. This is a writable tree with DomainMBean as the root. To make changes you will need to start an edit session via startEdit().   For more help, use help(edit)   Starting an edit session ... Started edit session, please be sure to save and activate your changes once you are done. Activating all your changes, this may take a while ... The edit lock associated with this edit session is released once the activation is completed. Activation completed Disconnected from weblogic server: examplesServer     Exiting WebLogic Scripting Tool.   Now if you go back and look in the console the changes have been made and we now have a compete script.  Of course there is a full MBean reference and you can learn the nuances of jython and WLST, but why not the WLS console do most of the work for you!  Happy scripting.

• jQuery Datatable in MVC &hellip; extended.

  - by Steve Clements

  There are a million plugins for jQuery and when a web forms developer like myself works in MVC making use of them is par-for-the-course!  MVC is the way now, web forms are but a memory!! Grids / tables are my focus at the moment.  I don’t want to get in to righting reems of css and html, but it’s not acceptable to simply dump a table on the screen, functionality like sorting, paging, fixed header and perhaps filtering are expected behaviour.  What isn’t always required though is the massive functionality like editing etc you get with many grid plugins out there. You potentially spend a long time getting everything hooked together when you just don’t need it. That is where the jQuery DataTable plugin comes in.  It doesn’t have editing “out of the box” (you can add other plugins as you require to achieve such functionality). What it does though is very nicely format a table (and integrate with jQuery UI) without needing to hook up and Async actions etc.  Take a look here… http://www.datatables.net I did in the first instance start looking at the Telerik MVC grid control – I’m a fan of Telerik controls and if you are developing an in-house of open source app you get the MVC stuff for free…nice!  Their grid however is far more than I require.  Note: Using Telerik MVC controls with your own jQuery and jQuery UI does come with some hurdles, mainly to do with the order in which all your jQuery is executing – I won’t cover that here though – mainly because I don’t have a clear answer on the best way to solve it! One nice thing about the dataTable above is how easy it is to extend http://www.datatables.net/examples/plug-ins/plugin_api.html and there are some nifty examples on the site already… I however have a requirement that wasn’t on the site … I need a grid at the bottom of the page that will size automatically to the bottom of the page and be scrollable if required within its own space i.e. everything above the grid didn’t scroll as well.  Now a CSS master may have a great solution to this … I’m not that master and so didn’t! The content above the grid can vary so any kind of fixed positioning is out. So I wrote a little extension for the DataTable, hooked that up to the document.ready event and window.resize event. Initialising my dataTable ( s )… $(document).ready(function () {   var dTable = $(".tdata").dataTable({ "bPaginate": false, "bLengthChange": false, "bFilter": true, "bSort": true, "bInfo": false, "bAutoWidth": true, "sScrollY": "400px" });   My extension to the API to give me the resizing….   // ********************************************************************** // jQuery dataTable API extension to resize grid and adjust column sizes // $.fn.dataTableExt.oApi.fnSetHeightToBottom = function (oSettings) { var id = oSettings.nTable.id; var dt = $("#" + id); var top = dt.position().top; var winHeight = $(document).height(); var remain = (winHeight - top) - 83; dt.parent().attr("style", "overflow-x: auto; overflow-y: auto; height: " + remain + "px;"); this.fnAdjustColumnSizing(); } This is very much is debug mode, so pretty verbose at the moment – I’ll tidy that up later! You can see the last call is a call to an existing method, as the columns are fixed and that normally involves so CSS voodoo, a call to adjust those sizes is required. Just above is the style that the dataTable gives the grid wrapper div, I got that from some firebug action and stick in my new height. The –83 is to give me the space at the bottom i require for fixed footer!   Finally I hook that up to the load and window resize.  I’m actually using jQuery UI tabs as well, so I’ve got that in the open event of the tabs.   $(document).ready(function () { var oTable; $("#tabs").tabs({ "show": function (event, ui) { oTable = $('div.dataTables_scrollBody>table.tdata', ui.panel).dataTable(); if (oTable.length > 0) { oTable.fnSetHeightToBottom(); } } }); $(window).bind("resize", function () { oTable.fnSetHeightToBottom(); }); }); And that all there is too it.  Testament to the wonders of jQuery and the immense community surrounding it – to which I am extremely grateful. I’ve also hooked up some custom column filtering on the grid – pretty normal stuff though – you can get what you need for that from their website.  I do hide the out of the box filter input as I wanted column specific, you need filtering turned on when initialising to get it to work and that input come with it!  Tip: fnFilter is the method you want.  With column index as a param – I used data tags to simply that one.

• RIDC Accelerator for Portal

  - by Stefan Krantz

  What is RIDC?Remote IntraDoc Client is a Java enabled API that leverages simple transportation protocols like Socket, HTTP and JAX/WS to execute content service operations in WebCenter Content Server. Each operation by design in the Content Server will execute stateless and return a complete result of the request. Each request object simply specifies the in a Map format (key and value pairs) what service to call and what parameters settings to apply. The result responded with will be built on the same Map format (key and value pairs). The possibilities with RIDC is endless since you can consume any available service (even custom made ones), RIDC can be executed from any Java SE application that has any WebCenter Content Services needs. WebCenter Portal and the example Accelerator RIDC adapter frameworkWebCenter Portal currently integrates and leverages WebCenter Content Services to enable available use cases in the portal today, like Content Presenter and Doc Lib. However the current use cases only covers few of the scenarios that the Content Server has to offer, in addition to the existing use cases it is not rare that the customer requirements requires additional steps and functionality that is provided by WebCenter Content but not part of the use cases from the WebCenter Portal.The good news to this is RIDC, the second good news is that WebCenter Portal already leverages the RIDC and has a connection management framework in place. The million dollar question here is how can I leverage this infrastructure for my custom use cases. Oracle A-Team has during its interactions produced a accelerator adapter framework that will reuse and leverage the existing connections provisioned in the webcenter portal application (works for WebCenter Spaces as well), as well as a very comprehensive design patter to minimize the work involved when exposing functionality. Let me introduce the RIDCCommon framework for accelerating WebCenter Content consumption from WebCenter Portal including Spaces. How do I get started?Through a few easy steps you will be on your way, Extract the zip file RIDCCommon.zip to the WebCenter Portal Application file structure (PortalApp) Open you Portal Application in JDeveloper (PS4/PS5) select to open the project in your application - this will add the project as a member of the application Update the Portal project dependencies to include the new RIDCCommon project Make sure that you WebCenter Content Server connection is marked as primary (a checkbox at the top of the connection properties form) You should by this stage have a similar structure in your JDeveloper Application Project Portal Project PortalWebAssets Project RIDCCommon Since the API is coming with some example operations that has already been exposed as DataControl actions, if you open Data Controls accordion you should see following: How do I implement my own operation? Create a new Java Class in for example com.oracle.ateam.portal.ridc.operation call it (GetDocInfoOperation) Extend the abstract class com.oracle.ateam.portal.ridc.operation.RIDCAbstractOperation and implement the interface com.oracle.ateam.portal.ridc.operation.IRIDCOperation The only method you actually are required to implement is execute(RIDCManager, IdcClient, IdcContext) The best practice to set object references for the operation is through the Constructor, example below public GetDocInfoOperation(String dDocName)By leveraging the constructor you can easily force the implementing class to pass right information, you can also overload the Constructor with more or less parameters as required Implement the execute method, the work you supposed to execute here is creating a new request binder and retrieve a response binder with the information in the request binder.In this case the dDocName for which we want the DocInfo Secondly you have to process the response binder by extracting the information you need from the request and restore this information in a simple POJO Java BeanIn the example below we do this in private void processResult(DataBinder responseData) - the new SearchDataObject is a Member of the GetDocInfoOperation so we can return this from a access method. Since the RIDCCommon API leverage template pattern for the operations you are now required to add a method that will enable access to the result after the execution of the operationIn the example below we added the method public SearchDataObject getDataObject() - this method returns the pre processed SearchDataObject from the execute method  This is it, as you can see on the code below you do not need more than 32 lines of very simple code 1: public class GetDocInfoOperation extends RIDCAbstractOperation implements IRIDCOperation { 2: private static final String DOC_INFO_BY_NAME = "DOC_INFO_BY_NAME"; 3: private String dDocName = null; 4: private SearchDataObject sdo = null; 5: 6: public GetDocInfoOperation(String dDocName) { 7: super(); 8: this.dDocName = dDocName; 9: } 10:   11: public boolean execute(RIDCManager manager, IdcClient client, 12: IdcContext userContext) throws Exception { 13: DataBinder dataBinder = createNewRequestBinder(DOC_INFO_BY_NAME); 14: dataBinder.putLocal(DocumentAttributeDef.NAME.getName(), dDocName); 15: 16: DataBinder responseData = getResponseBinder(dataBinder); 17: processResult(responseData); 18: return true; 19: } 20: 21: private void processResult(DataBinder responseData) { 22: DataResultSet rs = responseData.getResultSet("DOC_INFO"); 23: for(DataObject dobj : rs.getRows()) { 24: this.sdo = new SearchDataObject(dobj); 25: } 26: super.setMessage(responseData.getLocal(ATTR_MESSAGE)); 27: } 28: 29: public SearchDataObject getDataObject() { 30: return this.sdo; 31: } 32: } How do I execute my operation? In the previous section we described how to create a operation, so by now you should be ready to execute the operation Step one either add a method to the class  com.oracle.ateam.portal.datacontrol.ContentServicesDC or a class of your own choiceRemember the RIDCManager is a very light object and can be created where needed Create a method signature look like this public SearchDataObject getDocInfo(String dDocName) throws Exception In the method body - create a new instance of GetDocInfoOperation and meet the constructor requirements by passing the dDocNameGetDocInfoOperation docInfo = new GetDocInfoOperation(dDocName) Execute the operation via the RIDCManager instance rMgr.executeOperation(docInfo) Return the result by accessing it from the executed operationreturn docInfo.getDataObject() 1: private RIDCManager rMgr = null; 2: private String lastOperationMessage = null; 3:   4: public ContentServicesDC() { 5: super(); 6: this.rMgr = new RIDCManager(); 7: } 8: .... 9: public SearchDataObject getDocInfo(String dDocName) throws Exception { 10: GetDocInfoOperation docInfo = new GetDocInfoOperation(dDocName); 11: boolean boolVal = rMgr.executeOperation(docInfo); 12: lastOperationMessage = docInfo.getMessage(); 13: return docInfo.getDataObject(); 14: }   Get the binaries! The enclosed code in a example that can be used as a reference on how to consume and leverage similar use cases, user has to guarantee appropriate quality and support.  Download link: https://blogs.oracle.com/ATEAM_WEBCENTER/resource/stefan.krantz/RIDCCommon.zip RIDC API Referencehttp://docs.oracle.com/cd/E23943_01/apirefs.1111/e17274/toc.htm

• Pro ASP.NET MVC Framework Review

  - by Ben Griswold

  Early in my career, when I wanted to learn a new technology, I’d sit in the bookstore aisle and I’d work my way through each of the available books on the given subject.  Put in enough time in a bookstore and you can learn just about anything. I used to really enjoy my time in the bookstore – but times have certainly changed.  Whereas books used to be the only place I could find solutions to my problems, now they may be the very last place I look.  I have been working with the ASP.NET MVC Framework for more than a year.  I have a few projects and a couple of major deployments under my belt and I was able to get up to speed with the framework without reading a single book*.  With so many resources at our fingertips (podcasts, screencasts, blogs, stackoverflow, open source projects, www.asp.net, you name it) why bother with a book? Well, I flipped through Steven Sanderson’s Pro ASP.NET MVC Framework a few months ago. And since it is prominently displayed in my co-worker’s office, I tend to pick it up as a reference from time to time.  Last week, I’m not sure why, I decided to read it cover to cover.  Man, did I eat this book up.  Granted, a lot of what I read was review, but it was only review because I had already learned lessons by piecing the puzzle together for myself via various sources. If I were starting with ASP.NET MVC (or ASP.NET Web Deployment in general) today, the first thing I would do is buy Steven Sanderson’s Pro ASP.NET MVC Framework and read it cover to cover. Steven Sanderson did such a great job with this book! As much as I appreciated the in-depth model, view, and controller talk, I was completely impressed with all the extra bits which were included.  There a was nice overview of BDD, view engine comparisons, a chapter dedicated to security and vulnerabilities, IoC, TDD and Mocking (of course), IIS deployment options and a nice overview of what the .NET platform and C# offers.  Heck, Sanderson even include bits about webforms! The book is fantastic and I highly recommend it – even if you think you’ve already got your head around ASP.NET MVC.  By the way, procrastinators may be in luck.  ASP.NET MVC V2 Framework can be pre-ordered.  You might want to jump right into the second edition and find out what Sanderson has to say about MVC 2. * Actually, I did read through the free bits of Professional ASP.NET MVC 1.0.  But it was just a chapter – albeit a really long chapter.

• Connection Pooling is Busted

  - by MightyZot

  A few weeks ago we started getting complaints about performance in an application that has performed very well for many years.  The application is a n-tier application that uses ADODB with the SQLOLEDB provider to talk to a SQL Server database.  Our object model is written in such a way that each public method validates security before performing requested actions, so there is a significant number of queries executed to get information about file cabinets, retrieve images, create workflows, etc.  (PaperWise is a document management and workflow system.)  A common factor for these customers is that they have remote offices connected via MPLS networks. Naturally, the first thing we looked at was the query performance in SQL Profiler.  All of the queries were executing within expected timeframes, most of them were so fast that the duration in SQL Profiler was zero.  After getting nowhere with SQL Profiler, the situation was escalated to me.  I decided to take a peek with Process Monitor.  Procmon revealed some “gaps” in the TCP/IP traffic.  There were notable delays between send and receive pairs.  The send and receive pairs themselves were quite snappy, but quite often there was a notable delay between a receive and the next send.  You might expect some delay because, presumably, the application is doing some thinking in-between the pairs.  But, comparing the procmon data at the remote locations with the procmon data for workstations on the local network showed that the remote workstations were significantly delayed.  Procmon also showed a high number of disconnects. Wireshark traces showed that connections to the database were taking between 75ms and 150ms.  Not only that, but connections to a file share containing images were taking 2 seconds!  So, I asked about a trust.  Sure enough there was a trust between two domains and the file share was on the second domain.  Joining a remote workstation to the domain hosting the share containing images alleviated the time delay in accessing the file share.  Removing the trust had no affect on the connections to the database. Microsoft Network Monitor includes filters that parse TDS packets.  TDS is the protocol that SQL Server uses to communicate.  There is a certificate exchange and some SSL that occurs during authentication.  All of this was evident in the network traffic.  After staring at the network traffic for a while, and examining packets, I decided to call it a night.  On the way home that night, something about the traffic kept nagging at me.  Then it dawned on me…at the beginning of the dance of packets between the client and the server all was well.  Connection pooling was working and I could see multiple queries getting executed on the same connection and ethereal port.  After a particular query, connecting to two different servers, I noticed that ADODB and SQLOLEDB started making repeated connections to the database on different ethereal ports.  SQL Server would execute a single query and respond on a port, then open a new port and execute the next query.  Connection pooling appeared to be broken. The next morning I wrote a test to confirm my hypothesis.  Turns out that the sequence causing the connection nastiness goes something like this: Make a connection to the database. Open a result set that returns enough records to require multiple roundtrips to the server. For each result, query for some other data in the database (this will open a new implicit connection.) Close the inner result set and repeat for every item in the original result set. Close the original connection. Provided that the first result set returns enough data to require multiple roundtrips to the server, ADODB and SQLOLEDB will start making new connections to the database for each query executed in the loop.  Originally, I thought this might be due to Microsoft’s denial of service (ddos) attack protection.  After turning those features off to no avail, I eventually thought to switch my queries to client-side cursors instead of server-side cursors.  Server-side cursors are the default, by the way.  Voila!  After switching to client-side cursors, the disconnects were gone and the above sequence yielded two connections as expected. While the real problem is the amount of time it takes to make connections over these MPLS networks (100ms on average), switching to client-side cursors made the problem go away.  Believe it or not, this is actually documented by Microsoft, and rather difficult to find.  (At least it was while we were trying to troubleshoot the problem!)  So, if you’re noticing performance issues on slower networks, or networks with slower switching, take a look at the traffic in a tool like Microsoft Network Monitor.  If you notice a high number of disconnects, and you’re using fire-hose or server-side cursors, then try switching to client-side cursors and you may see the problem go away. Most likely, Microsoft believes this to be appropriate behavior, because ADODB can’t guarantee that all of the data has been retrieved when you execute the inner queries.  I’m not convinced, though, because the problem remains even after replacing all of the implicit connections with explicit connections and closing those connections in-between each of the inner queries.  In that case, there doesn’t seem to be a reason why ADODB can’t use a single connection from the connection pool to make the additional queries, bringing the total number of connections to two.  Instead ADO appears to make an assumption about the state of the connection. I’ve reported the behavior to Microsoft and am awaiting to hear from the appropriate team, so that I can demonstrate the problem.  Maybe they can explain to us why this is appropriate behavior.  :)

We will also use commons-logging-1.1.1, httpcomponents-client-4.0.1, httpcomponents-core-4.0.1 for writing the client to demonstrate.First we create a simple JSP which will always set response code to 304.The JSP snippet will look like <%@ page language="java"     contentType="text/xml;     charset=UTF-8"        pageEncoding="UTF-8" %><%      System.out.println("Servlet setting Responsecode=304");    response.setStatus(304);    response.flushBuffer();%>We will now deploy this JSP on weblogic server with URI=http://localhost:7021/reponsecode/For this JSP we will create a simple Any XML BS We will also create proxy service as shown below Once the proxy is created we configure pipeline for the proxy to use route node, which invokes the BS(JSPCaller) created in the first place. So now we will create a error handler for route node and will add a stage. When a HTTP BS sends a request, the JSP sends the response back. If the response code is not 200, then the http BS will consider that as error and the above configured error handler is invoked. We will print $outbound to show the response code sent by the JSP. The next actions. To test this I had create a simple clientimport org.apache.http.Header;import org.apache.http.HttpEntity;import org.apache.http.HttpHost;import org.apache.http.HttpResponse;import org.apache.http.HttpVersion;import org.apache.http.client.methods.HttpGet;import org.apache.http.conn.ClientConnectionManager;import org.apache.http.conn.scheme.PlainSocketFactory;import org.apache.http.conn.scheme.Scheme;import org.apache.http.conn.scheme.SchemeRegistry;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpParams;import org.apache.http.params.HttpProtocolParams;import org.apache.http.util.EntityUtils;/** * @author MNEELAPU * */public class TestProxy304{    public static void main(String arg[]) throws Exception{     HttpHost target = new HttpHost("localhost", 7021, "http");     // general setup     SchemeRegistry supportedSchemes = new SchemeRegistry();     // Register the "http" protocol scheme, it is required     // by the default operator to look up socket factories.     supportedSchemes.register(new Scheme("http",              PlainSocketFactory.getSocketFactory(), 7021));     // prepare parameters     HttpParams params = new BasicHttpParams();     HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);     HttpProtocolParams.setContentCharset(params, "UTF-8");     HttpProtocolParams.setUseExpectContinue(params, true);     ClientConnectionManager connMgr = new ThreadSafeClientConnManager(params,              supportedSchemes);     DefaultHttpClient httpclient = new DefaultHttpClient(connMgr, params);     HttpGet req = new HttpGet("/HttpResponseCode/ProxyExposed");     System.out.println("executing request to " + target);     HttpResponse rsp = httpclient.execute(target, req);     HttpEntity entity = rsp.getEntity();     System.out.println("----------------------------------------");     System.out.println(rsp.getStatusLine());     Header[] headers = rsp.getAllHeaders();     for (int i = 0; i < headers.length; i++) {         System.out.println(headers[i]);     }     System.out.println("----------------------------------------");     if (entity != null) {         System.out.println(EntityUtils.toString(entity));     }     // When HttpClient instance is no longer needed,      // shut down the connection manager to ensure     // immediate deallocation of all system resources     httpclient.getConnectionManager().shutdown();     }}On compiling and executing this we see the below output in STDOUT which clearly indicates the response code was propagated from Business Service to Proxy serviceexecuting request to http://localhost:7021----------------------------------------HTTP/1.1 304 Not ModifiedDate: Tue, 08 Jun 2010 16:13:42 GMTContent-Type: text/xml; charset=UTF-8X-Powered-By: Servlet/2.5 JSP/2.1----------------------------------------

• Tutorial: Criando um Componente para o UCM

  - by Denisd

  Então você já instalou o UCM, seguindo o tutorial: http://blogs.oracle.com/ecmbrasil/2009/05/tutorial_de_instalao_do_ucm.html e também já fez o hands-on: http://blogs.oracle.com/ecmbrasil/2009/10/tutorial_de_ucm.html e agora quer ir além do básico? Quer começar a criar funcionalidades para o UCM? Quer se tornar um desenvolvedor do UCM? Quer criar o Content Server à sua imagem e semelhança?! Pois hoje é o seu dia de sorte! Neste tutorial, iremos aprender a criar um componente para o Content Server. O nosso primeiro componente, embora não seja tão simples, será feito apenas com recursos do Content Server. Em um futuro tutorial, iremos aprender a usar classes java como parte de nossos componentes. Neste tutorial, vamos desenvolver um recurso de Favoritos, aonde os usuários poderão marcar determinados documentos como seus Favoritos, e depois consultar estes documentos em uma lista. Não iremos montar o componente com todas as suas funcionalidades, mas com o que vocês verão aqui, será tranquilo aprimorar este componente, inclusive para ambientes de produção. Componente MyFavorites Algumas características do nosso componente favoritos: - Por motivos de espaço, iremos montar este componente de uma forma “rápida e crua”, ou seja, sem seguir necessariamente as melhores práticas de desenvolvimento de componentes. Para entender melhor a prática de desenvolvimento de componentes, recomendo a leitura do guia Working With Components. - Ele será desenvolvido apenas para português-Brasil. Outros idiomas podem ser adicionados posteriormente. - Ele irá apresentar uma opção “Adicionar aos Favoritos” no menu “Content Actions” (tela Content Information), para que o usuário possa definir este arquivo como um dos seus favoritos. - Ao clicar neste link, o usuário será direcionado à uma tela aonde ele poderá digitar um comentário sobre este favorito, para facilitar a leitura depois. - Os favoritos ficarão salvos em uma tabela de banco de dados que iremos criar como parte do componente - A aba “My Content Server” terá uma opção nova chamada “Meus Favoritos”, que irá trazer uma tela que lista os favoritos, permitindo que o usuário possa deletar os links - Alguns recursos ficarão de fora deste exercício, novamente por motivos de espaço. Mas iremos listar estes recursos ao final, como exercícios complementares. Recursos do nosso Componente O componente Favoritos será desenvolvido com alguns recursos. Vamos conhecer melhor o que são estes recursos e quais são as suas funções: - Query: Uma query é qualquer atividade que eu preciso executar no banco, o famoso CRUD: Criar, Ler, Atualizar, Deletar. Existem diferentes jeitos de chamar a query, dependendo do propósito: Select Query: executa um comando SQL, mas descarta o resultado. Usado apenas para testar se a conexão com o banco está ok. Não será usado no nosso exercício. Execute Query: executa um comando SQL que altera informações do banco. Pode ser um INSERT, UPDATE ou DELETE. Descarta os resultados. Iremos usar Execute Query para criar, alterar e excluir os favoritos. Select Cache Query: executa um comando SQL SELECT e armazena os resultados em um ResultSet. Este ResultSet retorna como resultado do serviço e pode ser manipulado em IDOC, Java ou outras linguagens. Iremos utilizar Select Cache Query para retornar a lista de favoritos de um usuário. - Service: Os serviços são os responsáveis por executar as queries (ou classes java, mas isso é papo para um outro tutorial...). O serviço recebe os parâmetros de entrada, executa a query e retorna o ResultSet (no caso de um SELECT). Os serviços podem ser executados através de templates, páginas IDOC, outras aplicações (através de API), ou diretamente na URL do browser. Neste exercício criaremos serviços para Criar, Editar, Deletar e Listar os favoritos de um usuário. - Template: Os templates são as interfaces gráficas (páginas) que serão apresentadas aos usuários. Por exemplo, antes de executar o serviço que deleta um documento do favoritos, quero que o usuário veja uma tela com o ID do Documento e um botão Confirma, para que ele tenha certeza que está deletando o registro correto. Esta tela pode ser criada como um template. Neste exercício iremos construir templates para os principais serviços, além da página que lista todos os favoritos do usuário e apresenta as ações de editar e deletar. Os templates nada mais são do que páginas HTML com scripts IDOC. A nossa sequência de atividades para o desenvolvimento deste componente será: - Criar a Tabela do banco - Criar o componente usando o Component Wizard - Criar as Queries para inserir, editar, deletar e listar os favoritos - Criar os Serviços que executam estas Queries - Criar os templates, que são as páginas que irão interagir com os usuários - Criar os links, na página de informações do conteúdo e no painel My Content Server Pois bem, vamos começar! Confira este tutorial na íntegra clicando neste link: http://blogs.oracle.com/ecmbrasil/Tutorial_Componente_Banco.pdf   Happy coding!  :-)

• Configure clean URLs using Laravel using a rewrite rule to index.php

  - by yannis hristofakis

  Recently I've started learning Laravel , I have none experience with framework before. I'm encountering the following problem .I'm trying to configure the .htaccess file so I can have clean URLs but the only thing I get are 404 Not Found error pages. I have created a virtual host - you can see below the configuration file - and changed the .htaccesss file on the public directory. /etc/apache2/sites-available <VirtualHost *:80> ServerAdmin [email protected] ServerName laravel.lar DocumentRoot "/home/giannis/Desktop/laravel/public" <Directory "/home/giannis/Desktop/laravel/public"> Options Indexes FollowSymLinks MultiViews AllowOverride All </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

• Create a Slide Show in Windows 7 Media Center

  - by DigitalGeekery

  Are you looking for a nice way to create and display a slide show from your photo collection? Today we’ll show you how to create a slide show, how to add music to it, and watch it from the comfort of your couch in Windows 7 Media Center. Create Slide Show Launch Windows 7 Media Center and click on the Picture Library tile found under Pictures and Videos.   In the Pictures Library, scroll across to slide shows and click on Create Slide show.   Enter a name for the slide show and click Next.   If you are using a Windows Media Center remote, click on the OK button to bring up the onscreen keyboard. Use the directional buttons to navigate across the keyboard and press OK to select each letter. Click Done when finished. Select Picture Library and click Next. Select the pictures to include in your slide show. If using a remote, navigate through the images and press OK to select. If you are using a mouse, simply click on the selections. When you are finished, click Next.    Now, we can review and edit the slide show. Click the up or down pointing arrows to move pictures up and down in the order.  (more intuitive titles would be helpful in this case as opposed to the randomly generated titles in the example below) If you are finished, click Create. You can also choose to go back and add music to your slide show. (or even more pictures) We’ll take a look at adding some music in our example. Click on the Add More button.   Add Music to Your Slide Show Here we’ll select Music Library to add a song. Click Next.   You’ll now be able to browse your Music Library to select songs for your slide show. Select your songs and click Next.   When you are finished adding Music and Pictures click Create.   Once your slide show is saved, you can play it any time by going to clicking on slide shows in the Picture Library, then selecting the slide show title. Select play slide show when you’re ready to enjoy your new production.   If you ever want to edit or delete the slide show, select it in the Picture Library, and scroll to Actions. You’ll see those option under additional commands. You have the option to Edit Slide Show, Burn a CD/DVD, or Delete. Editing Slide Show Settings Within Media Center, go to Tasks… Click on Pictures…   Then choose Slide Shows. From the Slide Show settings you have the option to Show pictures in random order, Show picture information, Show song information, and Use Pan and zoom effect. You can also adjust the length of time to display each picture, and change the background color. Be sure to click Save to apply and changes before exiting. If you choose to show picture information, the picture title, date, and star rating will be displayed in the top right.   If your slide show is accompanied by music and you choose to show song information, you will get a translucent overlay for a few seconds at the beginning of each song to indicate the song, album, and artist. One of the really cool things about creating a slide show in Windows 7 Media Center is you can complete the entire process using just a Media Center remote. Can’t get enough slide shows?

• SQL SERVER – Auditing and Profiling Database Made Easy with SQL Audit and Comply

  - by Pinal Dave

  Do you like auditing your database, or can you think of about a million other things you’d rather do?  Unfortunately, auditing is incredibly important.  As with tax audits, it is important to audit databases to ensure they are following all the rules, but they are also important for troubleshooting and security. There are several ways to audit SQL Server.  There is manual auditing, which is going through your database “by hand,” and obviously takes a long time and is quite inefficient.  SQL Server also provides programs to help you audit your systems.  Different administrators will have different opinions about best practices and which tools to use, and each one will be perfected for certain systems and certain users. Today, though, I would like to talk about Apex SQL Audit.  It is an auditing tool that acts like “track changes” in a word processing document.  It will log what has changed on the database, who made the changes, and what effects these changes have had (i.e. what objects were affected down the line).  All this information is logged, and can be easily viewed or printed for easy access. One of the best features of Apex is that it is so customizable (and easy to use!).  First, start Apex.  Then you can connect to the database you would like to monitor. Once you select your database, you can select which table you want to audit. You can customize right down to the field you’d like to audit, and then select which types of actions you’d like tracked – insert, delete, or update.  Repeat these steps for every database you want monitored. To create the logs, choose “Create triggers” in the menu.  The script written here will be what logs each insert, delete, and update function.  Press F5 to execute.  All this tracking information will be stored in AUDIT_LOG_DATA and AUDIT_LOG_TRANSACTIONS tables.  View these tables using ApexSQL Audit reports. These transaction logs can be extremely detailed – especially on very busy servers, where every move it traced.  Reading them can be overwhelming, to say the least.  Apex has tried to make things easier for the average DBA, though. You can read these tracking logs in Apex, and it will display data and objects that affect your server – even things that were happening on your server before you installed Apex! To read these logs, open Apex, and connect to that database you want to audit. Go to the Transaction Logs tab, and add the logs you want to read. To narrow down what results you want to see, you can use the Filter tab to choose time, operation type, name, users, and more. Click Open, and you can see the results in a grid (as shown below).  You can export these results to CSV, HTML, XML or SQL files and save on the hard disk. One of the advantages is that since there are no triggers here, there are no other processes that will affect SQL Server performance.  Using this method is also how to view history from your database that occurred before Apex was installed.  This type of tracking does require storage space for the data sources, as the database must be fully running, and the transaction logs must exist (things not stored in the transactions logs will not be recoverable). Apex can also replace SQL Server Profiler and SQL Server Traces – which are much more complex and error-prone – with its ApexSQL Comply.  It can do fault tolerant auditing, centralized reporting, and “who saw what” information in an easy-to-use interface.  The tracking settings can be altered by the user, or the default options will provide solutions to the most common auditing problems. To get started: open ApexSQL Comply, and selected Database Filter Settings to choose which database you’d like to audit.  You can select which tracking you’re like in Operation Types – DML, DDL, queries executed, execute statements, and more.  To get started, click Start Auditing. After this, every action will be stored in the central repository database (ApexSQLCrd).  You can view the audit and create a report (or view the standard default report) using a wizard. You can see how easy it is to use ApexSQL Comply.  You can easily set audits, including the type and time, and create customized reports.  Remote users can easily access the reports through the user interface (available online, as well), and security concerns are all taken care of by the program.  Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQL Utility, T SQL, Technology

• Replication - between pools in the same system

  - by Steve Tunstall

  OK, I fully understand that's it's been a LONG time since I've blogged with any tips or tricks on the ZFSSA, and I'm way behind. Hey, I just wrote TWO BLOGS ON THE SAME DAY!!! Make sure you keep scrolling down to see the next one too, or you may have missed it. To celebrate, for the one or two of you out there who are still reading this, I got something for you. The first TWO people who make any comment below, with your real name and email so I can contact you, will get some cool Oracle SWAG that I have to give away. Don't get excited, it's not an iPad, but it pretty good stuff. Only the first two, so if you already see two below, then settle down. Now, let's talk about Replication and Migration.  I have talked before about Shadow Migration here: https://blogs.oracle.com/7000tips/entry/shadow_migrationShadow Migration lets one take a NFS or CIFS share in one pool on a system and migrate that data over to another pool in the same system. That's handy, but right now it's only for file systems like NFS and CIFS. It will not work for LUNs. LUN shadow migration is a roadmap item, however. So.... What if you have a ZFSSA cluster with multiple pools, and you have a LUN in one pool but later you decide it's best if it was in the other pool? No problem. Replication to the rescue. What's that? Replication is only for replicating data between two different systems? Who told you that? We've been able to replicate to the same system now for a few code updates back. These instructions below will also work just fine if you're setting up replication between two different systems. After replication is complete, you can easily break replication, change the new LUN into a primary LUN and then delete the source LUN. Bam. Step 1- setup a target system. In our case, the target system is ourself, but you still have to set it up like it's far away. Go to Configuration-->Services-->Remote Replication. Click the plus sign and setup the target, which is the ZFSSA you're on now. Step 2. Now you can go to the LUN you want to replicate. Take note which Pool and Project you're in. In my case, I have a LUN in Pool2 called LUNp2 that I wish to replicate to Pool1.  Step 3. In my case, I made a Project called "Luns" and it has LUNp2 inside of it. I am going to replicate the Project, which will automatically replicate all of the LUNs and/or Filesystems inside of it.  Now, you can also replicate from the Share level instead of the Project. That will only replicate the share, and not all the other shares of a project. If someone tells you that if you replicate a share, it always replicates all the other shares also in that Project, don't listen to them.Note below how I can choose not only the Target (which is myself), but I can also choose which Pool to replicate it to. So I choose Pool1.  Step 4. I did not choose a schedule or pick the "Continuous" button, which means my replication will be manual only. I can now push the Manual Replicate button on my Actions list and you will see it start. You will see both a barber pole animation and also an update in the status bar on the top of the screen that a replication event has begun. This also goes into the event log.  Step 5. The status bar will also log an event when it's done. Step 6. If you go back to Configuration-->Services-->Remote Replication, you will see your event. Step 7. Done. To see your new replica, go to the other Pool (Pool1 for me), and click the "Replica" area below the words "Filesystems | LUNs" Here, you will see any replicas that have come in from any of your sources. It's a simple matter from here to break the replication, which will change this to a "Local" LUN, and then delete the original LUN back in Pool2. Ok, that's all for now, but I promise to give out more tricks sometime in November !!! There's very exciting stuff coming down the pipe for the ZFSSA. Both new hardware and new software features that I'm just drooling over. That's all I can say, but contact your local sales SC to get a NDA roadmap talk if you want to hear more.   Happy Halloween,Steve

• doubleTwist is an iTunes Alternative that Supports Several Devices

  - by Mysticgeek

  There are a lot of iTunes users out there, but unfortunately you can’t use it with all of your portable devices. Today we take a look at doubleTwist, which allows you to sync your media with a multitude of portable devices and easily share it as well. Note: You can run doubleTwist on Windows or Mac, and here we take a look at the Windows version. Install & Setup doubleTwist Download and install doubleTwist using the defaults in the wizard… Installation takes several moments and you’ll see the progress while it finishes up. After installation is complete, sign up for an account if you don’t already have one. If you do have an account you can login right away. Enter in your username, email address, and password then click Sign Up.   You’ll get an confirmation email and need to activate the account before you can sign in. Once you’re all signed up, launch doubleTwist and you’ll be ready to start using it. doubleTwist Music The default music store is Amazon MP3 store which might appeal to those of you who are tired of the iTunes music store. A lot of times the music is cheaper and available at higher bit rates. You can start searching for music in the Amazon Music Store and previewing songs. To purchase anything though you will need to sign into your Amazon account.   Under Playlists it allows you to import your playlists from iTunes and Windows Media Player, which is a handy feature if you don’t want to set them up again. Of course you can play your songs through the music player on your desktop. Devices One of the coolest things about doubleTwist is that it supports a lot of different portable media devices including iPod, BlackBerry, Windows Mobile, Android, PSP, Smartphones, and much more. Unfortunately for Zune users…there isn’t any support for the Zune of Zune HD yet. Here we have a Creative Zen attached and can sync songs, pictures, and podcasts. An HTC-S620 Smartphone running Windows Mobile… Even a simple USB drive will be recognized and you can transfer your media to it as well.   Podcasts Finding your favorite audio and video podcasts is easy with the search feature. You can easily manage and subscribe to podcasts in the subscriptions section.   You can watch the video podcasts directly in doubleTwist. Sharing Media Also you can share digital media with your friends or add it to Flickr and YouTube. You can send any pictures, videos, or music in your library to other people by dragging it over. You can email users individually… Or access contacts from your Gmail and Yahoo accounts. There is a limit to how much you can send of video podcasts… only the first 10 minutes. The person you send it to will get a link in their email that points to your My Feed page on the doubleTwist site.   There they can access the media you sent…in this example it’s a video podcast but you can share any media. Other Features Under My Profile you can change your avatar and personal information.   In Preferences you can choose where media is stored, its startup actions, podcast subscriptions, and manage device syncing. Conclusion It’s still in beta stage so expect some bugs, but overall doubleTwist is a solid media player that is easy to use with a clean interface. It’s simple and doesn’t try to do too much so is fairly easy on system resources. The main annoyance is it tries to catalog all of your media out of the box. Which may be alright for some users with smaller media collections, but very irritating to advanced users with large collections. Also there is currently no support for the Zune, but according to their forums, it’s on the way. At the time of this writing it’s in public beta and can be downloaded for XP, Vista, Windows 7 (32 & 64 bit), and Mac OSX. If you’re looking for an iTunes alternative that works with several different portable devices, you might want to give DoubleTwist a try.

• ASP.NET Web API - Screencast series Part 4: Paging and Querying

  - by Jon Galloway

  We're continuing a six part series on ASP.NET Web API that accompanies the getting started screencast series. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. In Part 1 we looked at what ASP.NET Web API is, why you'd care, did the File / New Project thing, and did some basic HTTP testing using browser F12 developer tools. In Part 2 we started to build up a sample that returns data from a repository in JSON format via GET methods. In Part 3, we modified data on the server using DELETE and POST methods. In Part 4, we'll extend on our simple querying methods form Part 2, adding in support for paging and querying. This part shows two approaches to querying data (paging really just being a specific querying case) - you can do it yourself using parameters passed in via querystring (as well as headers, other route parameters, cookies, etc.). You're welcome to do that if you'd like. What I think is more interesting here is that Web API actions that return IQueryable automatically support OData query syntax, making it really easy to support some common query use cases like paging and filtering. A few important things to note: This is just support for OData query syntax - you're not getting back data in OData format. The screencast demonstrates this by showing the GET methods are continuing to return the same JSON they did previously. So you don't have to "buy in" to the whole OData thing, you're just able to use the query syntax if you'd like. This isn't full OData query support - full OData query syntax includes a lot of operations and features - but it is a pretty good subset: filter, orderby, skip, and top. All you have to do to enable this OData query syntax is return an IQueryable rather than an IEnumerable. Often, that could be as simple as using the AsQueryable() extension method on your IEnumerable. Query composition support lets you layer queries intelligently. If, for instance, you had an action that showed products by category using a query in your repository, you could also support paging on top of that. The result is an expression tree that's evaluated on-demand and includes both the Web API query and the underlying query. So with all those bullet points and big words, you'd think this would be hard to hook up. Nope, all I did was change the return type from IEnumerable<Comment> to IQueryable<Comment> and convert the Get() method's IEnumerable result using the .AsQueryable() extension method. public IQueryable<Comment> GetComments() { return repository.Get().AsQueryable(); } You still need to build up the query to provide the $top and $skip on the client, but you'd need to do that regardless. Here's how that looks: $(function () { //--------------------------------------------------------- // Using Queryable to page //--------------------------------------------------------- $("#getCommentsQueryable").click(function () { viewModel.comments([]); var pageSize = $('#pageSize').val(); var pageIndex = $('#pageIndex').val(); var url = "/api/comments?$top=" + pageSize + '&$skip=' + (pageIndex * pageSize); $.getJSON(url, function (data) { // Update the Knockout model (and thus the UI) with the comments received back // from the Web API call. viewModel.comments(data); }); return false; }); }); And the neat thing is that - without any modification to our server-side code - we can modify the above jQuery call to request the comments be sorted by author: $(function () { //--------------------------------------------------------- // Using Queryable to page //--------------------------------------------------------- $("#getCommentsQueryable").click(function () { viewModel.comments([]); var pageSize = $('#pageSize').val(); var pageIndex = $('#pageIndex').val(); var url = "/api/comments?$top=" + pageSize + '&$skip=' + (pageIndex * pageSize) + '&$orderby=Author'; $.getJSON(url, function (data) { // Update the Knockout model (and thus the UI) with the comments received back // from the Web API call. viewModel.comments(data); }); return false; }); }); So if you want to make use of OData query syntax, you can. If you don't like it, you're free to hook up your filtering and paging however you think is best. Neat. In Part 5, we'll add on support for Data Annotation based validation using an Action Filter.

• Creating a Reverse Proxy with URL Rewrite for IIS

  - by OWScott

  There are times when you need to reverse proxy through a server. The most common example is when you have an internal web server that isn’t exposed to the internet, and you have a public web server accessible to the internet. If you want to serve up traffic from the internal web server, you can do this through the public web server by creating a tunnel (aka reverse proxy). Essentially, you can front the internal web server with a friendly URL, even hiding custom ports. For example, consider an internal web server with a URL of http://10.10.0.50:8111. You can make that available through a public URL like http://tools.mysite.com/ as seen in the following image. The URL can be made public or it can be used for your internal staff and have it password protected and/or locked down by IP address. This is easy to do with URL Rewrite and IIS. You will also need Application Request Routing (ARR) installed even though for a simple reverse proxy you won’t use most of ARR’s functionality. If you don’t already have URL Rewrite and ARR installed you can do so easily with the Web Platform Installer. A lot can be said about reverse proxies and many different situations and ways to route the traffic and handle different URL patterns. However, my goal here is to get you up and going in the easiest way possible. Then you can dig in deeper after you get the base configuration in place. URL Rewrite makes a reverse proxy very easy to set up. Note that the URL Rewrite Add Rules template doesn’t include Reverse Proxy at the server level. That’s not to say that you can’t create a server-level reverse proxy, but the URL Rewrite rules template doesn’t help you with that. Getting Started First you must create a website on your public web server that has the public bindings that you need. Alternately, you can use an existing site and route using conditions for certain traffic. After you’ve created your site then open up URL Rewrite at the site level. Using the “Add Rule(s)…” template that is opened from the right-hand actions pane, create a new Reverse Proxy rule. If you receive a prompt (the first time) that the proxy functionality needs to be enabled, select OK. This is telling you that a proxy can route traffic outside of your web server, which happens to be our goal in this case. Be aware that reverse proxy rules can be dangerous if you open sites from inside you network to the world, so just be aware of what you’re doing and why. The next and final step of the template asks a few questions. The first textbox asks the name of the internal web server. In our example, it’s 10.10.0.50:8111. This can be any URL, including a subfolder like internal.mysite.com/blog. Don’t include the http or https here. The template assumes that it’s not entered. You can choose whether to perform SSL Offloading or not. If you leave this checked then all requests to the internal server will be over HTTP regardless of the original web request. This can help with performance and SSL bindings if all requests are within a trusted network. If the network path between the two web servers is not completely trusted and safe then uncheck this. Next, the template enables you to create an outbound rule. This is used to rewrite links in the page to look like your public domain name rather than the internal domain name. Outbound rules have a lot of CPU overhead because the entire web content needs to be parsed and updated. However, if you need it, then it’s well worth the extra CPU hit on the web server. If you check the “Rewrite the domain names of the links in HTTP responses” checkbox then the From textbox will be filled in with what you entered for the inbound rule. You can enter your friendly public URL for the outbound rule. This will essentially replace any reference to 10.10.0.50:8111 (or whatever you enter) with tools.mysite.com in all <a>, <form>, and <img> tags on your site. That’s it! Well, there is a lot more that you can do, this but will give you the base configuration. You can now visit www.mysite.com on your public web server and it will serve up the site from your internal web server. You should see two rules show up; one inbound and one outbound. You can edit these, add conditions, and tweak them further as needed. One common issue that can occur without outbound rules has to do with compression. If you run into errors with the new proxied site, try turning off compression to confirm if that’s the issue. Here’s a link with details on how to deal with compression and outbound rules. I hope this was helpful to get started and to see how easy it is to create a simple reverse proxy using URL Rewrite for IIS.

• Auto Mocking using JustMock

  - by mehfuzh

  Auto mocking containers are designed to reduce the friction of keeping unit test beds in sync with the code being tested as systems are updated and evolve over time. This is one sentence how you define auto mocking. Of course this is a more or less formal. In a more informal way auto mocking containers are nothing but a tool to keep your tests synced so that you don’t have to go back and change tests every time you add a new dependency to your SUT or System Under Test. In Q3 2012 JustMock is shipped with built in auto mocking container. This will help developers to have all the existing fun they are having with JustMock plus they can now mock object with dependencies in a more elegant way and without needing to do the homework of managing the graph. If you are not familiar with auto mocking then I won't go ahead and educate you rather ask you to do so from contents that is already made available out there from community as this is way beyond the scope of this post. Moving forward, getting started with Justmock auto mocking is pretty simple. First, I have to reference Telerik.JustMock.Container.DLL from the installation folder along with Telerik.JustMock.DLL (of course) that it uses internally and next I will write my tests with mocking container. It's that simple! In this post first I will mock the target with dependencies using current method and going forward do the same with auto mocking container. In short the sample is all about a report builder that will go through all the existing reports, send email and log any exception in that process. This is somewhat my  report builder class looks like: Reporter class depends on the following interfaces: IReporBuilder: used to  create and get the available reports IReportSender: used to send the reports ILogger: used to log any exception. Now, if I just write the test without using an auto mocking container it might end up something like this: Now, it looks fine. However, the only issue is that I am creating the mock of each dependency that is sort of a grunt work and if you have ever changing list of dependencies then it becomes really hard to keep the tests in sync. The typical example is your ASP.NET MVC controller where the number of service dependencies grows along with the project. The same test if written with auto mocking container would look like: Here few things to observe: I didn't created mock for each dependencies There is no extra step creating the Reporter class and sending in the dependencies Since ILogger is not required for the purpose of this test therefore I can be completely ignorant of it. How cool is that ? Auto mocking in JustMock is just released and we also want to extend it even further using profiler that will let me resolve not just interfaces but concrete classes as well. But that of course starts the debate of code smell vs. working with legacy code. Feel free to send in your expert opinion in that regard using one of telerik’s official channels. Hope that helps
