  • ADF Faces now in Eclipse

    - by shay.shmeltzer
    The new version of Oracle Enterprise Pack for Eclipse was just release, and one of the key new feature it offers is integration of Oracle ADF Faces development in Eclipse. If you are serious about developing with JSF, you probably know by now that ADF Faces is the richest set of components out there both in terms of number of components and also the functionality they offer. The components offer a lot of Ajax functionality out of the box, and the framework also offers windowing, drag and drop, push, Javascript API, skinning and much more. OEPE makes it simple to build with ADF Faces and test run your application. Here is a basic tutorial that will get you all set up to use this combination. Once you do that, you can then do this:

    Greetings everyone!If you're reading this, hopefully it's because you have been following our series of webcasts on Oracle 11gR2 that we've been hosting on Wordpress. If you found us some other way, well that's even better - the more the merrier as they say.In either case, welcome to our new blog!!!

  • Gain Quick Access to the Cache in Firefox

    - by Asian Angel
    Are you looking for a quick and simple way to view the contents of the cache in Firefox? Then you will definitely want to see how easy it can be using the CacheViewer extension. Note: CacheViewer is a front-end app for easily accessing and searching the memory cache. Before Viewing the cache in Firefox using “about:cache” provides some information about the contents but may not be the most efficient method available for some people. CacheViewer in Action Once you have installed the extension there are three easy ways to access your new cache viewer. The first is using the “CacheViewer Command” available in the “Tools Menu” and the second is using the keyboard shortcut “Ctrl + Shift + C”. The third way is by adding a “Toolbar Button” to your browser’s UI. All three work equally well…choose the method that best suits your personal needs. When you access the “CacheViewer Window” this is what it will look like. You may decide to resize it and move (or hide) some of the columns for the best viewing. You can easily scroll through the cache contents and preview images if desired as shown here. If you keep the “CacheViewer Window” open you can refresh it as you browse using the “Refresh Button” in the lower right corner. This is a nice, quick, and very simple way to access the cache on demand and save items to your hard-drive if desired. Note: The “CacheViewer” can also be set to open in a new tab instead (see “Options”). Options Choose whether “CacheViewer” opens in a separate window (default) or in a new tab. Conclusion If you want a quick and simple way to view the cache in Firefox then the CacheViewer extension is just what you have been looking for.

  • Is your test method self-validating ?

    - by mehfuzh
    Writing state of art unit tests that can validate your every part of the framework is challenging and interesting at the same time, its like becoming a samurai. One of the key concept in this is to keep our test synced all the time as underlying code changes and thus breaking them to the furthest unit as possible.  This also means, we should avoid  multiple conditions embedded in a single test. Let’s consider the following example of transfer funds. [Fact] public void ShouldAssertTranserFunds() {     var currencyService = Mock.Create<ICurrencyService>();     //// current rate     Mock.Arrange(() => currencyService.GetConversionRate("AUS", "CAD")).Returns(0.88f);       Account to = new Account { Currency = "AUS", Balance = 120 };     Account from = new Account { Currency = "CAD" };       AccountService accService = new AccountService(currencyService);       Assert.Throws<InvalidOperationException>(() => accService.TranferFunds(to, from, 200f));       accService.TranferFunds(to, from, 100f);       Assert.Equal(from.Balance, 88);     Assert.Equal(20, to.Balance); } At first look,  it seems ok but as you look more closely , it is actually doing two tasks in one test. At line# 10 it is trying to validate the exception for invalid fund transfer and finally it is asserting if the currency conversion is successfully made. Here, the name of the test itself is pretty vague. The first rule for writing unit test should always reflect to inner working of the target code, where just by looking at their names it is self explanatory. Having a obscure name for a test method not only increase the chances of cluttering the test code, but it also gives the opportunity to add multiple paths into it and eventually makes things messy as possible. I would rater have two test methods that explicitly describes its intent and are more self-validating. ShouldThrowExceptionForInvalidTransferOperation ShouldAssertTransferForExpectedConversionRate Having, this type of breakdown also helps us pin-point reported bugs easily rather wasting any time on debugging for something more general and can minimize confusion among team members. Finally, we should always make our test F.I.R.S.T ( Fast.Independent.Repeatable.Self-validating.Timely) [ Bob martin – Clean Code]. Only this will be enough to ensure, our test is as simple and clean as possible.   Hope that helps

  • FREE Windows Azure evening in London on April 15th including FREE access to Windows Azure

    - by Eric Nelson
    [Did I overdo the use of FREE in the title? :-)] April 12th to 16th is Microsoft Tech Days – 5 days of sessions on Visual Studio 2010 through to Windows 7 Phone Series. Many of these days are now full (Tip - Thursday still has room if rich client applications is your thing) but the good news is the development community in the UK has pulled together an awesome series of “fringe events” during April in London and elsewhere in the UK. There are sessions on Silverlight, SQL Server 2008 R2, Sharepoint 2010 and … the Windows Azure Platform. The UK AzureNET user group is planning to put on a great evening and AzureNET will be giving away hundreds of free subscriptions to the Windows Azure Platform during the evening. The subscription includes up to 20 Windows Azure Compute nodes and 3 SQL Azure databases for you to play with over the 2 weeks following the event. This is a great opportunity to really explore the Windows Azure Platform in detail – without a credit card! Register now! (and you might also want to join the UK Fans of Azure Community while I have your attention) FYI The Thursday day time event includes an introduction to Windows Azure session delivered by my colleague David – which would be an ideal session to attend if you are new to Azure and want to get the most out of the evening session. 7:00pm: See the difference: How Windows Azure helped build a new way of giving Simon Evans and James Broome (@broomej) They will cover the business context for Azure and then go into patterns used and lessons learnt from the project....as well as showing off the app of course! 8:00pm: UK AzureNET update 8:15pm: NoSQL databases or: How I learned to love the hash table Mark Rendle (@markrendle) In this session Mark will look at how Azure Table Service works and how to use it. We’ll look briefly at the high-level Data Services SDK, talk about its limitations, and then quickly move on to the REST API and how to use it to improve performance and reduce costs. We’ll make-up some pretend real-world problems and solve them in new and interesting ways. We’ll denormalise data (for fun and profit). We’ll talk about how certain social networking sites can deal with huge volumes of data so quickly, and why it sometimes goes wrong. Check out the complete list of fringe events which covers the UK fairly well:

  • E-Business Suite Technology Stack Roadmap (April 2010) Now Available

    - by Steven Chan
    Keeping up with our E-Business Suite technology stack roadmap can be challenging.  Regular readers of this blog know that we certify new combinations and versions of Oracle products with the E-Business Suite every few weeks.  We also update our certification plans and roadmap as new third-party products like Microsoft Office 2010 and Firefox are announced or released.  Complicating matters further, various Oracle products leave Premier Support or are superceded by more-recent versions.This constant state of change means that any static representation of our roadmap is really a snapshot in time, and a snapshot that might begin to yellow and fade fairly quickly.  With that caveat in mind, here's this month's snapshot that I presented at the OAUG/Collaborate 2010 conference in Las Vegas last week:EBS Technology Stack Roadmap (April 2010)

  • Change default language settings in Visual Studio 2012

    - by sreejukg
    The first thing you need to do after the installation of Visual Studio 2012 is to choose the IDE preferences. Once you select your preferred collection of settings, the IDE will always choose dialogs and other options according to your selection. Nowadays developer’s needs to work with different programming environments and due to this, developers might need to reset the default settings. In this article, I am going to demonstrate how you can change the default settings in Visual Studio 2012. For the purpose of this demonstration, I have installed Visual Studio 2012 and selected C++ as my default environment settings. So now when I go to file -> new project, it will give me C++ templates by default as follows. If you want to select another language, you need to expand Other Languages section and select C# or VB. Now I am going to change these default settings. I am going to change the default language preference to C#. In Visual Studio 2012, go to tools menu and select Import and Export Settings. Here you have 3 options; one is to export the current settings so that the settings are saved for future use. Also you can import previously saved settings. The last option available is to reset it to default. It is a good Idea to export your settings and import it as you need in later stages. To reset the settings to default select the Reset option and click next. Now Visual Studio will ask you to whether you would like to save the settings, which can be used in future to restore. Select any one option and click next. For the purpose of this demo, I have selected not to save the settings. Click Next button to continue. Now Visual Studio will bring you the similar dialog that appears just after installation to select your IDE settings. Select the required settings from the available list and click Finish button. Click Finish once you are done. If everything OK, you will see the success message as below. Now go to file -> new Project, you will see the selected language appear by default. I selected C# in the previous step and the new project dialog appears as follows. Changing IDE settings in Visual Studio 2012 is very easy and straight forward.

  • Watching Green Day and discovering Sitecore, priceless.

    - by jonel
    I’m feeling inspired and I’d like to share a technique we’ve implemented in Sitecore to address a URL mapping from our legacy site that we wanted to carry over to the new beautiful Littelfuse.com. The challenge is to carry over all of our series URLs that have been published in our datasheets, we currently have a lot of series and having to create a manual mapping for those could be really tedious. It has the format of http://www.littelfuse.com/series/series-name.html, for instance, http://www.littelfuse.com/series/flnr.html. It would have been easier if we have our information architecture defined like this but that would have been too easy. I took a solution that is 2-fold. First, I need to create a URL rewrite rule using the IIS URL Rewrite Module 2.0. Secondly, we need to implement a handler that will take care of the actual lookup of the actual series. It will be amazing after we’ve gone over the details. Let’s start with the URL rewrite. Create a new blank rule, you can name it with anything you wish. The key part here to talk about is the Pattern and the Action groups. The Pattern is nothing but regex. Basically, I’m telling it to match the regex I have defined. In the Action group, I am telling it what to do, in this case, rewrite to the redirect.aspx webform. In this implementation, I will be using Rewrite instead of redirect so the URL sticks in the browser. If you opt to use Redirect, then the URL bar will display the new URL our webform will redirect to. Let me explain one small thing, the (\w+) in my Pattern group’s regex, will actually translate to {R:1} in my Action’s group. This is where the magic begins. Now let’s see what our Redirect.aspx contains. Remember our {R:1} above which becomes the query string variable s? This are basic .Net code. The only thing that you will probably ask is the LFSearch class. It’s our own implementation of addressing finding items by using a field search, we supply the fieldname, the value of the field, the template name of the item we are after, and the value of true or false if we want to do an exact search, or not. If eureka, then redirect to that item’s Path (Url). If not, tell the user tough luck, here’s the 404 page as a consolation. Amazing, ain’t it?

  • ASP.NET Localization: Enabling resource expressions with an external resource assembly

    - by Brian Schroer
    I have several related projects that need the same localized text, so my global resources files are in a shared assembly that’s referenced by each of those projects. It took an embarrassingly long time to figure out how to have my .resx files generate “public” properties instead of “internal” so I could have a shared resources assembly (apparently it was pretty tricky pre-VS2008, and my “googling” bogged me down some out-of-date instructions). It’s easy though – Just change the “Custom Tool” to “PublicResXFileCodeGenerator”:    …which can be done via the “Access Modifier” dropdown of the resource file designer window:   A reference to my shared resources DLL gives me the ability to use the resources in code, but by default, the ASP.NET resource expression syntax: <asp:Button ID="BeerButton" runat="server" Text="<%$ Resources:MyResources, Beer %>" />   …assumes that your resources are in your web site project.   To make resource expressions work with my shared resources assembly, I added two classes to the resources assembly: 1) a custom IResourceProvider implementation:   1: using System; 2: using System.Web.Compilation; 3: using System.Globalization; 4:   5: namespace DuffBeer 6: { 7: public class CustomResourceProvider : IResourceProvider 8: { 9: public object GetObject(string resourceKey, CultureInfo culture) 10: { 11: return MyResources.ResourceManager.GetObject(resourceKey, culture); 12: } 13:   14: public System.Resources.IResourceReader ResourceReader 15: { 16: get { throw new NotSupportedException(); } 17: } 18: } 19: }   2) and a custom factory class inheriting from the ResourceProviderFactory base class:   1: using System; 2: using System.Web.Compilation; 3:   4: namespace DuffBeer 5: { 6: public class CustomResourceProviderFactory : ResourceProviderFactory 7: { 8: public override IResourceProvider CreateGlobalResourceProvider(string classKey) 9: { 10: return new CustomResourceProvider(); 11: } 12:   13: public override IResourceProvider CreateLocalResourceProvider(string virtualPath) 14: { 15: throw new NotSupportedException(String.Format( 16: "{0} does not support local resources.", 17: this.GetType().Name)); 18: } 19: } 20: }   In the “system.web / globalization” section of my web.config file, I point the “resourceProviderFactoryType" property to my custom factory:   <system.web> <globalization culture="auto:en-US" uiCulture="auto:en-US" resourceProviderFactoryType="DuffBeer.CustomResourceProviderFactory, DuffBeer" />   This simple approach met my needs for these projects , but if you want to create reusable resource provider and factory classes that allow you to specify the assembly in the resource expression, the instructions are here.

  • 2010's Most Popular Articles

    The end of the year is upon us, 2010 is about to be in the books. When closing out a year I like to take a look back at the articles I wrote over the year and see which ones resonated the most with readers. Which ones generated the most reader emails? Which ones were read the most? Such a retrospective analysis highlights what content was of most interest to developers in the trenches, and this data is used to guide article topics in the new year. I ended last year with a "Best Of" article - see 2009's Most Popular Articles - and decided to continue this tradition. Such "Best Of" articles give both regular and new readers a chance to discover (or rediscover) the most favored content from the year. So here it is - a list and synopsis of the 2010's most popular articles on 4GuysFromRolla.com. Read More >

  • Triggering custom events in AJAX callbacks

    - by Sabrina Gelbart
    I'm pretty new to JavaScript, but one of the things that's been frustrating is that our AJAX callbacks have been getting packed with different functionality, making it difficult to keep everything separated and organized. I'm really new to programming, I have a feeling learning MVC a bit more would help me, but for now using custom events seems like it could help me keep my code a lot cleaner and prevent some problems. Here's what I'm talking about: function myAjaxFunction(){ $.post('ajax/test.html', function(data) { $(document).trigger('testDataLoaded',data); }); } function myOtherFunctionThatsDependentUponAjax(){ $(document).one('testDataLoaded', function(data){ alert (data); } } I also don't know if it's ok that I'm triggering document or not... Are there any patterns that look like this that I can read more about? What are the potential problems with this?

  • Save Links for Later Reading in Firefox

    - by Asian Angel
    Do you want a simple way to save and manage links for reading later? The Save-To-Read extension for Firefox makes it easy to do without an account. Using Save-To-Read As soon as you install the extension you will notice two new additions to your UI. You will see a small plus sign in the address bar and a new toolbar button (opens and closes the sidebar shown here). Your bookmarks menu will also have a new folder entry. For our example we chose to save three pages for later reading. Each time you want to save a website click on the small plus sign, and it is automatically added to your read later list. Our second article… And finally the third article. Notice that the small plus sign has become a minus sign after adding the article to our list. Opening the sidebar shows our three entries waiting to be read. Checking the bookmarks menu shows the same articles available there. When you are ready to read your articles simply click on the link in the sidebar, bookmarks menu, etc. Notice that the entry is still available at the moment…there are no automatic deletions until you are finished with an article. This is great if you accidentally click the wrong link before you are ready for it. Removing an article from the list is as simple as clicking on the address bar minus sign. It will revert to a plus sign and the entry is no longer visible in your list. For those who want to avoid using a sidebar there is a different toolbar button available too. The alternate toolbar button provides access to a drop-down article list. Choose the access style that best suits your needs. Preferences The preferences are simple to work with and focus on appearance/ease-of-use. Conclusion If you have been looking for a simpler alternative to other “read later” extensions, then Save-To-Read could be just what you have been waiting for.

  • Ghost Incognito Automatically Loads Incognito Mode Based on Domain

    - by Jason Fitzpatrick
    Chrome: Ghost Incognito mode is a simple Chrome extension that automatically launches Incognito mode on a domain-by-domain basis. If you routinely visit the same sites using Incognito Mode, Ghost Incognito allows you to flag domains. By default it turns on Incognito for all .XXX domains and, once you select some domains, for any that you specify. Thus if you flag angrybirds.com, as we did for our test run of the app, every time you visit angrybirds.com or a sub-domain there of such as shop.angrybirds.com, you’ll be automatically directed to a new Incognito tab–no input from you necessary.

  • How to UEFI install Ubuntu 12.10?

    - by Geezanansa
    Running a newer FM1 motherboard which is using an AMD 3870k APU with a new 1TB HDD. Following the advice in the motherboard manual and https://help.ubuntu.com/community/UEFI have now got to grub option screen for UEFI install. see http://imgur.com/VW5vz The dvd.iso being used is Ubuntu 12.10 desktop amd64 from ubuntu .com. The hdd has had a gpt partition table made for, by using gparted when in a live desktop session when booted in bios mode. (*edit/update: Although the old cd updates on running it is an old kernel and it did make a gpt but that version of gparted uses fdisk whereas gdisk is required to make gpt. Think am going to have to spend more time here http://www.dedoimedo.com/computers/gparted.html lol Using the gparted from 12.10 live session to make partitions; following the guidance regarding this at https://help.ubuntu.com/community/UEFI#Creating_an_EFI_partition, but can only boot to grub option screen http://imgur.com/VW5vz when 12.10 options to "try ubuntu" or "install ubuntu" are selected they give errors as described below*) but after making the gpt decided to leave it unformatted/unallocated space with the intention of using installer to set up partitions. update-originally but gparted now sees hdd as http://imgur.com/hFIvm as described above. *Booting live dvd in EFI mode gives "Secure Boot not installed" just before grub kernel option list with the option to "install ubuntu" but get "can not read cd/0" and "the kernel must be loaded first" errors; when that option is selected. Any pointers on how to get installer going for UEFI install would be good. Thanks in advance. update: Hopefully these screenshots can help better highlight where i am going wrong or if there is something else going on http://imgur.com/g30RB, http://imgur.com/VW5vz, http://imgur.com/31E0q, http://imgur.com/bnuaG, http://imgur.com/y4KGu, http://imgur.com/3u2QE, http://imgur.com/n9lN3, http://imgur.com/FEKvz, http://imgur.com/hFIvm, update: Thank you fernando garcia for pointing me in the right direction to start the process of elimantion. What i have done since asking question is a little home work starting here http://askubuntu.com/faq#bounty and here http://askubuntu.com/questions/how-to-ask. Looking at other similar questions was good fun and found this 12.10 UEFI Secure Boot install the most relative in helping getting ubuntu to uefi install on my system. In response to wolverine's question this article was referred to http://web.dodds.net/~vorlon/wiki/blog/SecureBoot_in_Ubuntu_12.10/ This article in the first sentence gives a link to http://www.ubuntu.com/download which is where i downloaded the 12.10 desktop amd64 .iso(and others) but have been unable to do a efi install of ubuntu on this system and as this is a new system have ended up just going with bios installer running which at least puts my mind at ease that i have not bricked my new mobo.(had to do a clrcmos and flash to latest bios version) So it possibly could be the bios settings or the bios version being used that is problem. To try and eliminate bios version i can not get to post screen in order to id bios version being used. Pressing tab to show post instead of logo and trying to pausebreak to catch post is proving difficult. If logo screen in bios is disabled just get black screen no post shown and pressing tab does not show post. Appreciate using appropriate bios settings and latest 12.10 release should simply get uefi installer running when selected from the grub list (nice graphic details in Identifying if computer boots the cd in efi mode section at https://help.ubuntu.com/community/UEFI#Identifying_if_the_computer_boots_the_CD_in_EFI_mode) And to confirm the hdd is booting in efi mode https://help.ubuntu.com/community/UEFI#Identifying_if_the_computer_boots_the_HDD_in_EFI_mode running the command [ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD" gave Legacy boot on HDD This is as expected because i allowed the bios installer (which was 12.04 desktop amd64 after trying 12.10 desktop amd64 in efi mode) to run to get a working installation. Which is not what was intended or wished for but wanted to get a working os to bench test new mobo i.e. prove it is working. There are other options as in installing other bootmanagers/loaders but do not wish to do so as shim should get grub2 going that is after secure boot has been signed.(Now got rough idea what should happen just it aint happening. Is it possible ahci drivers are required?) Will post boot info script url of the updated config/setup. The original question asked seems irrelevant to what is being said in this update but as the problem is not resolved will keep on trying efi installing! i.e the problem is same as when question asked just trying to update. Have tried to edit and update the best i can!

  • How do I set up a "gateway" for a specific subdomain?

    I'm looking at setting up a website that will run a few different apps. Most of them can be managed by an Apache server, but I've got one specific thing that will run on a custom HTTP server. Looking around on apache.org, it looks like you can use mod_proxy to configure Apache to act as a "reverse proxy" and forward requests from a specific subdirectory to a new server with the ProxyPass directive. So if I wanted send anything from mysite.com/special on to the custom server, that's how I would do it. But what if I want to set it up as a subdomain instead? The documentation doesn't seem to cover that. If, I wanted to make it forward anything from special.mysite.com to the new server, how would I set that up?

  • Working with Joins in LINQ

    - by vik20000in
    While working with data most of the time we have to work with relation between different lists of data. Many a times we want to fetch data from both the list at once. This requires us to make different kind of joins between the lists of data. LINQ support different kinds of join Inner Join     List<Customer> customers = GetCustomerList();     List<Supplier> suppliers = GetSupplierList();      var custSupJoin =         from sup in suppliers         join cust in customers on sup.Country equals cust.Country         select new { Country = sup.Country, SupplierName = sup.SupplierName, CustomerName = cust.CompanyName }; Group Join – where By the joined dataset is also grouped.     List<Customer> customers = GetCustomerList();     List<Supplier> suppliers = GetSupplierList();      var custSupQuery =         from sup in suppliers         join cust in customers on sup.Country equals cust.Country into cs         select new { Key = sup.Country, Items = cs }; We can also work with the Left outer join in LINQ like this.     List<Customer> customers = GetCustomerList();     List<Supplier> suppliers = GetSupplierList();      var supplierCusts =         from sup in suppliers         join cust in customers on sup.Country equals cust.Country into cs         from c in cs.DefaultIfEmpty()  // DefaultIfEmpty preserves left-hand elements that have no matches on the right side         orderby sup.SupplierName         select new { Country = sup.Country, CompanyName = c == null ? "(No customers)" : c.CompanyName,                      SupplierName = sup.SupplierName};Vikram

  • Ranking - an Introduction

    - by PointsToShare
    © 2011 By: Dov Trietsch. All rights reserved Ranking Ranking is quite common in the internet. Readers are asked to rank their latest reading by clicking on one of 5 (sometimes 10) stars. The number of stars is then converted to a number and the average number of stars as selected by all the readers is proudly (or shamefully) displayed for future readers. SharePoint 2007 lacked this feature altogether. SharePoint 2010 allows the users to rank items in a list or documents in a library (the two are actually the same because a library is actually a list). But in SP2010 the computation of the average is done later on a timer rather than on-the-spot as it should be. I suspect that the reason for this shortcoming is that they did not involve a mathematician! Let me explain. Ranking is kept in a related list. When a user rates a document the rank-list is added an item with the item id, the user name, and his number of stars. The fact that a user already ranked an item prevents him from ranking it again. This prevents the creator of the item from asking his mother to rank it a 5 and do it 753 times, thus stacking the ballot. Some systems will allow a user to change his rating and this will be done by updating the rank-list item. Now, when the timer kicks off, the list is spanned and for each item the rank-list items containing this id are summed up and divided by the number of votes thus yielding the new average. This is obviously very time consuming and very server intensive. In the 18th century an early actuary named James Dodson used what the great Augustus De Morgan (of De Morgan’s law) later named Commutation tables. The labor involved in computing a life insurance premium was staggering and also very error prone. Clerks with pencil and paper would multiply and add mountains of numbers to do the task. The more steps the greater the probability of error and the more expensive the process. Commutation tables created a “summary” of many steps and reduced the work 100 fold. So had Microsoft taken a lesson in the history of computation, they would have developed a much faster way for rating that may be done in real-time and is also 100 times faster and less CPU intensive. How do we do this? We use a form of commutation. We always keep the number of votes and the total of stars. One simple division gives us the average. So we write an event receiver. When a vote is added, we just add the stars to the total-stars and 1 to the number of votes. We then recomputed the average. When a vote is updated, we reduce the total by the old vote, increase it by the new vote and leave the number of votes the same. Again we do the division to get the new average. When a vote is deleted (highly unlikely and maybe even prohibited), we reduce the total by that vote and reduce the number of votes by 1… Gone are the days of spanning lists, counting items, and tallying votes and we have no need for a timer process to run it all. This is the first of a few treatises on ranking. Even though I discussed the math and the history thereof, in here I am only going to solve the presentation issue. I wanted to create the CSS and Jscript needed to display the stars, create the various effects like hovering and clicking (onmouseover, onmouseout, onclick, etc.) and I wanted to create a general solution with any number of stars. When I had it all done, I created the ranking game so that I could test it. The game is interesting in and on itself, so here it is (or go to the games page and select “rank the stars”). BTW, when you play it, look at the source code and see how it was all done.  Next, how the 5 stars are displayed in the New and Update forms. When the whole set of articles will be done, you’ll be able to create the complete solution. That’s all folks!

  • LightFish, Adam Bien's lightweight telemetry application

    - by alexismp
    Adam Bien (Java Champion, JavaEE expert, book author, etc...), has been a GlassFish enthusiast for a while and he proves it again with his new open source project - LightFish, a lightweight monitoring and visualization application for GlassFish. Adam has a short intro and screencast about this standalone WAR application. The tool uses the new JavaEE 6 self-described JDBC connection and the GlassFish-bundled Derby database to provide drag-and-drop install. At runtime, once monitoring is enabled, calls to the RESTful admin API for GlassFish are emitted from a JavaFX dashboard plotting in real-time telemetry data on charts and graphs, including data for "Paranormal Activity". Check it out!

  • TSAM 11gR1

    - by todd.little
    The Tuxedo System and Application Monitor (TSAM) 11gR1 release provides powerful new application monitoring capabilities, as well as significant improvements in ease of use. The first thing users will notice is the completely redesigned user interface in the TSAM console. Based on Oracle ADF, the console is much easier to navigate, provides a Web 2.0 style interface with dynamically updating panels, and a look and feel familiar to those that have used Oracle Enterprise Manager. Monitoring data can be viewed in both tabular and graphical form and exported to Excel for further analysis. A number of new metrics are collected and displayed in this release. Call path monitoring now displays CPU time, message size, total transport time, and client address giving even more end-to-end information about a specific Tuxedo request. As well the call path display has been completely revamped to make it much easier to see the branches of the call path. The call pattern display now provides statistics on successful vs failed calls, system and application failures, and end-to-end average elapsed time. Service monitoring now displays minimum and maximum message size, CPU usage, and client address. System server monitoring now includes monitoring the SALT gateway servers to provide detailed performance metrics about those servers. Perhaps the most significant new feature is the consolidation of alert definitions and policy management. In previous versions of TSAM, some alerts were defined and checked on the monitored systems while others were defined and checked in the console. Policy management could be performed on both the monitored node via environment variable or command, as well as from the console. Now all alert definitions and policy definitions are only made using the console. For alerts this means that regardless of where the alert is evaluated it is defined in one and only one place. Thus the plug-in alert mechanism of previous releases can now be managed using the TSAM console, making SLA alert definition much easier and cleaner. Finally there is support in TSAM for monitoring rehosted mainframe applications. The newly announced Oracle Tuxedo Application Runtime for CICS and Batch can be monitored in the TSAM console using traditional mainframe views of the application such as regions. Look for a future blog entry with more details on this as well as some entries providing a glimpse of the console. TSAM gives users a single point for monitoring the performance of all of their Tuxedo applications.

  • Remote Debug Windows Azure Cloud Service

    - by Shaun
    Originally posted on: http://geekswithblogs.net/shaunxu/archive/2013/11/02/remote-debug-windows-azure-cloud-service.aspxOn the 22nd of October Microsoft Announced the new Windows Azure SDK 2.2. It introduced a lot of cool features but one of it shocked most, which is the remote debug support for Windows Azure Cloud Service (a.k.a. WACS).   Live Debug is Nightmare for Cloud Application When we are developing against public cloud, debug might be the most difficult task, especially after the application had been deployed. In order to minimize the debug effort, Microsoft provided local emulator for cloud service and storage once the Windows Azure platform was announced. By using local emulator developers could be able run their application on local machine with almost the same behavior as running on Windows Azure, and that could be debug easily and quickly. But when we deployed our application to Azure, we have to use log, diagnostic monitor to debug, which is very low efficient. Visual Studio 2012 introduced a new feature named "anonymous remote debug" which allows any workstation under any user could be able to attach the remote process. This is less secure comparing the authenticated remote debug but much easier and simpler to use. Now in Windows Azure SDK 2.2, we could be able to attach our application from our local machine to Windows Azure, and it's very easy.   How to Use Remote Debugger First, let's create a new Windows Azure Cloud Project in Visual Studio and selected ASP.NET Web Role. Then create an ASP.NET WebForm application. Then right click on the cloud project and select "publish". In the publish dialog we need to make sure the application will be built in debug mode, since .NET assembly cannot be debugged in release mode. I enabled Remote Desktop as I will log into the virtual machine later in this post. It's NOT necessary for remote debug. And selected "advanced settings" tab, make sure we checked "Enable Remote Debugger for all roles". In WACS, a cloud service could be able to have one or more roles and each role could be able to have one or more instances. The remote debugger will be enabled for all roles and all instances if we checked. Currently there's no way for us to specify which role(s) and which instance(s) to enable. Finally click "publish" button. In the windows azure activity window in Visual Studio we can find some information about remote debugger. To attache remote process would be easy. Open the "server explorer" window in Visual Studio and expand "cloud services" node, find the cloud service, role and instance we had just published and wanted to debug, right click on the instance and select "attach debugger". Then after a while (it's based on how fast our Internet connect to Windows Azure Data Center) the Visual Studio will be switched to debug mode. Let's add a breakpoint in the default web page's form load function and refresh the page in browser to see what's happen. We can see that the our application was stopped at the breakpoint. The call stack, watch features are all available to use. Now let's hit F5 to continue the step, then back to the browser we will find the page was rendered successfully.   What Under the Hood Remote debugger is a WACS plugin. When we checked the "enable remote debugger" in the publish dialog, Visual Studio will add two cloud configuration settings in the CSCFG file. Since they were appended when deployment, we cannot find in our project's CSCFG file. But if we opened the publish package we could find as below. At the same time, Visual Studio will generate a certificate and included into the package for remote debugger. If we went to the azure management portal we will find there will a certificate under our application which was created, uploaded by remote debugger plugin. Since I enabled Remote Desktop there will be two certificates in the screenshot below. The other one is for remote debugger. When our application was deployed, windows azure system will open related ports for remote debugger. As below you can see there are two new ports opened on my application. Finally, in our WACS virtual machine, windows azure system will copy the remote debug component based on which version of Visual Studio we are using and start. Our application then can be debugged remotely through the visual studio remote debugger. Below is the task manager on the virtual machine of my WACS application.   Summary In this post I demonstrated one of the feature introduced in Windows Azure SDK 2.2, which is Remote Debugger. It allows us to attach our application from local machine to windows azure virtual machine once it had been deployed. Remote debugger is powerful and easy to use, but it brings more security risk. And since it's only available for debug build this means the performance will be worse than release build. Hence we should only use this feature for staging test and bug fix (publish our beta version to azure staging slot), rather than for production.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.
