  • Updating an ADF Web Service Data Control When Service Structure or Location Change

    - by Shay Shmeltzer
    The web service data control in Oracle ADF gives you a simplified approach to consuming services in ADF applications, and now with ADF Mobile the usage of this service seems to be growing. A frequent question we get is what happens if the service that I'm consuming changes - how do I update my data control? Well, first we should mention that if you do a good design of your application before you actually code - then things like Web service method signature shouldn't change. The signature is the contract between the publisher and the consumer, and contracts shouldn't be broken. But in reality things do change during development stages, so here is how you can update both method signatures and service location with the Web service data control: After watching this video you might be tempted to not copy the WSDLs to your project - which lets you use the right click update on a data control. However there is a reason why the copy is on by default, it reduces network traffic when you are actually running your application since ADF doesn't need to go to the server to find out the service structure. So for runtime performance, you probably should keep the WSDL local.  I encourage you to further look into both the connections.xml file where your service location is saved, and the datacontrols.dcx file where its definition is kept to get an even deeper understanding of how ADF works underneath the declarative layers.

  • Is there a command-line utility app which can find a specific block of lines in a text file, and replace it?

    - by fred.bear
    UPDATE (see end of question) The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :) UPDATE: ..(sub-update) My following comment about reasons when not use sed are only in the context of; don't push any tool too far beyond its design intent (I use sed quite often, and consider it to be invaluable.) I just now found an interesting web page about sed and when not to use it. So, because of all the sed answers, I"ll post the link.. it is part of the sed FAQ on sourceforge Also, I'm pretty sure there is some way diff can do the job of locating the block of text (once it's located, the replacement is quite straight foward; using head and tail) ... 'diff' dumps all the necessary data, but I haven't yet worked out how to filter it , ... (I'm still working on it)

  • Google search question, front page not showing...

    - by Catelyn
    I know this is probably a dumb question but I hope someone can give me some insight; I was ranked on Google first page of search results for "funny st patricks day shirts" but I was third from the bottom and not familiar enough with SEO, so I signed up for "Attracta" to rank higher. Big mistake. Since using Attracta, I've lost the first page and I'm now on the fourth page in that search. What I noticed is that Google is now just showing a sub-page or side page, (a link from my front page, to a page which has only a few designs in it) this is not where I would want customers to land first... but my front page is not showing in that search anymore. Obviously, the title of this side page is not geared toward that search result, so I know that's why I have the pr drop. Why is my front page not ranking over that page, though? Why is it apparently gone from that search, or so far back no one will ever find it? I need to know how to fix this quick if anyone has any advice at all for me. It's the busiest season for my website and the people who were stealing design ideas from me are all ranked higher than my site now. (I can prove this, lol) So, I'm very frustrated by that. I would be very grateful to have any advice at all as to what I can do to fix this. THANKS in advance for any advice you can offer. Catelyn

  • We'll be at QCon San Francisco!

    - by Carlos Chang
    Oracle Technology Network is a Platinum sponsor at QCon San Francisco. Don’t miss these great developer focused sessions: Shay Shmeltzer - How we simplified Web, Mobile and Cloud development for our own developers? - the Oracle Story Over the past several years, Oracle has beendeveloping a new set of enterprise applications in what is probably one of the largest Java based development project in the world. How do you take 3000 developers and make them productive? How do you insure the delivery of cutting edge UIs for both Mobile and Web channels? How do you enable Cloud based development and deployment? Come and learn how we did it at Oracle, and see how the same technologies and methodologies can apply to your development efforts. Dan Smith - Project Lambda in Java 8 Java SE 8 will include major enhancements to the Java Programming Language and its core libraries.  This suite of new features, known as Project Lambda in the OpenJDK community, includes lambda expressions, default methods, and parallel collections (and much more!).  The result will be a next-generation Java programming experience with more flexibility and better abstractions.   This talk will introduce the new Java features and offer a behind-the-scenes view of how they evolved and why they work the way that they do. Arun Gupta - JSR 356: Building HTML5 WebSocket Applications in Java The family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform. The complete conference schedule is here: http://qconsf.com/sf2012/schedule/wednesday.jsp But wait, there’s more! At the Oracle booth, we’ll also be covering: Oracle ADF Mobile Oracle Developer Cloud Service Oracle ADF Essentials NetBeans Project Easel Hope to see you there!

  • Book Review&ndash;Getting Started With OAuth 2.0

    - by Lori Lalonde
    Getting Started With OAuth 2.0, by Ryan Boyd, provides an introduction to the latest version of the OAuth protocol. The author starts off by exploring the origins of OAuth, along with its importance, and why developers should care about it. The bulk of this book involves a discussion of the various authorization flows that developers will need to consider when developing applications that will incorporate OAuth to manage user access and authorization. The author explains in detail which flow is appropriate to use based on the application being developed, as well as how to implement each type with step-by-step examples. Note that the examples in the book are focused on the Google and Facebook APIs. Personally, I would have liked to see some examples with the Twitter API as well. In addition to that, the author also discusses security considerations, error handling (what is returned if the access request fails), and access tokens (when are access tokens refreshed, and how access can be revoked). This book provides a good starting point for those developers looking to understand what OAuth is and how they can leverage it within their own applications. The book wraps up with a list of tools and libraries that are available to further assist the developer in exploring the APIs supporting the OAuth specification. I highly recommend this book as a must-read for developers at all levels that have not yet been exposed to OAuth. The eBook format of this book was provided free through O'Reilly's Blogger Review program. This book can be purchased from the O'Reilly book store at: : http://shop.oreilly.com/product/0636920021810.do

  • What is the basic loadout for an open source web developer?

    - by DeveloperDon
    Thus far, I have mainly been an embedded developer, but I am interested in having the flexibility to do mobile and web development as well. I think my tools should include the following, but probably a lot more. LAMP stack. Java IDEs like Eclipse and IntelliJ. JS frameworks like Dojo, Node.JS, AngularJS, (is it better to mix or commit to one?). Cloud solutions like EC2 and Azure (again, ok to mix or better to commit to one?). Google APIs. Continuous integration server. Source control tools with Git for new work, SVN, CVS, +others for imports. FTP server. Unit test runners. Bug trackers. OOAD modeling tools or plug-ins? Graphic design tools? Hosting services. XML / JSON / other markup? Content management, SEO? I am also interested to know if there are tools where it might be better to mix, match, or support all available (maybe for source control) and others where the full focus should be on one (maybe Java vs. C# or Windows vs. Linux vs. MacOS). Perhaps some of these questions need context of whether the projects will be greenfield (just pick favorite) or maintenance (no choice, each project continues legacy, sometimes with a poor tools).

  • flat files vs. RDBMS database, few read/writes, few changes

    - by Bob Lapique
    I have to handle data from long term (years, decades) climate monitoring stations. The data flow usually starts with raw data (voltages, etc.) plus quality check information (pressure, temperature, flow rate, etc.) generally recorded @ 1Hz. Then, the data are assigned a quality flag (human and/or program), processed (apply calibration curves) and flagged. So, we basically end up with 2 datasets : raw and processed data. New data are typically added once a day (~500Ko/day/instrument). Simultaneous queries are not likely to ever happen. I wanted to go for a RDBMS (we have a MySQL server) and have some experience in database design, but the IT guy keeps telling me that flat files will to the job just as well. I suspect him to try to make his life easier when it comes to backup/upgrade the MySQL. There are not so many links between data, they don't change much, but the quality flags will change. A RDBMS is easier to compare data from different instruments on a "many days" scale, compared to daily text files. Well, what would you advise ? Thanks.

  • How to overcome politics of the net (Google translate code refuses to work from a specific region) [closed]

    - by Jawad
    Possible Duplicate: How to overcome politics of the net (Google translate code refuses to work from a specific region) I have this Web Site. It uses the Google Translate API (Can't post the link, does not open from this region) with the following code. <meta name="google-translate-customization" content="9f841e7780177523-3214ceb76f765f38-gc38c6fe6f9d06436-c"></meta> <script type="text/javascript"> function googleTranslateElementInit() { new google.translate.TranslateElement({pageLanguage: 'en'}, 'google_translate_element'); } </script> <script type="text/javascript" src="http://translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script> The problem is since this, it just stopped working. On the site you can see that I had to actually remove the above from here, here, and here while left it here, here, here and here. This is so because the the web site "refuses" to load at all with the pages that have the code (i.e., from this region.) If I use Firefox Stealthy Plugin and open the site in Firefox, It works like a charm without any problems. But with Google Chrome, Apple Safari and Opera Web browser, the site does not load/open at all because of the Google translate. (I know this because If I remove the Google Translate Code, the site works/loads fine) It was one thing to program for "cross browser compatability" and alltogether another to program for "cross region compatability". What can I do to make sure that the site works from anywhere? Do I completely remove the Google Translate code and just have to do without the additional functionality or Do I look for alternatives like this or according to this?

  • How to code Time Stop or Bullet Time in a game?

    - by David Miler
    I am developing a single-player RPG platformer in XNA 4.0. I would like to add an ability that would make the time "stop" or slow down, and have only the player character move at the original speed(similar to the Time Stop spell from the Baldur's Gate series). I am not looking for an exact implementation, rather some general ideas and design-patterns. EDIT: Thanks all for the great input. I have come up with the following solution public void Update(GameTime gameTime) { GameTime newGameTime = new GameTime(gameTime.TotalGameTime, new TimeSpan(gameTime.ElapsedGameTime.Ticks / DESIRED_TIME_MODIFIER)); gameTime = newGameTime; or something along these lines. This way I can set a different time for the player component and different for the rest. It certainly is not universal enough to work for a game where warping time like this would be a central element, but I hope it should work for this case. I kinda dislike the fact that it litters the main Update loop, but it certainly is the easiest way to implement it. I guess that is essentialy the same as tesselode suggested, so I'm going to give him the green tick :)

  • AndEngine Box2d game

    - by OneMoreVladimir
    I'm developing a 2d survival shooter using Box2d extension and I've got some questions: I have two AnalogOnScreenControls. Their listeners modify both sprites and bodies. I receive TouchEventPool was exhausted and as their number grows the game crashes accidently. I've tried to put the modification of the bodies and sprites on the UpdateThread but that does not solve the problem. What could be the cause? I have a class that at the beginnig of the game loads all the textures. After I relaunch the game activity several times I receive Unable to find Phys Addr for and "green color" interface. But that doesn't happen if I clear the memory manually through the Task Manager before relaunch What could be the cause? I unload my atlas at the end of the game. The game sometimes crashes at start with NullPointerException in onResumeGame. The solution suggested is to set android:configChanges="orientation|screenSize" but my device is API 10 so it doesn't have screenSize property and orientation only does not seem to help, because the game starts in portrait mode at times (though landscape is set in the code)

  • Best way to implement mouse-based movement in MMOG

    - by fiftyeight
    I want to design an MMO where players click the destination they want to walk to with their mouse and the character moves there, similar to Runescape in this manner. I think it should be easier than keyboard movement since the client can simply send the server the destination each time the player clicks on a destination. The main thing I'm trying to decide is what to do when there are obstacles in the way. It's no problem to implement a simple path-finding solution on the client, the question is if the server will do path-finding as well, since it'll probably take too much Computation power from the server. What I though is that when there is an obstacle the client will send only the first coordinate it plans to go to and then when he gets there he'll send the next coordinate automatically. For example if there is a rock in the way the character will decide on a route that is made of two destinations so it goes around the rock and when it arrives at the first destination it sends the next coordinate. That way if the player changes destination is the middle he won't send unnecessary information. Is this a good way to implement it and is there a standard way MMOGs usually do it? EDIT: I should also mention that the server will make sure all movements are legal and there aren't any walls in the way etc. In the way I wrote it should be quite easy since all movements will be sent in straight lines so the server will just check there aren't any obstacles along that line.

  • EclipseLink does multitenancy. Today.

    - by alexismp
    So you heard Java EE 7 will be about the cloud, but that didn't mean a whole lot to you. Then it was characterized as PaaS, something in between IaaS and SaaS. And finally it all became clear when referenced as support for multitenancy. Or did it? When it comes to JPA and persistence is general, multitenancy is defined as the ability to share a database schema among various groups of users (i.e. tenants). This means that there is no database setup or reconfiguration required as the data is co-located in the same database. EclipseLink 2.3 (the Indigo train release) let's you do just that by supporting tenant discriminator column(s) via annotations or XML with applications providing values for these discriminators via an API or PU configuration. Check out details here. EclipseLink 2.3 is scheduled to be the default and supported JPA provider for GlassFish 3.1.1. Another nice feature of this release is the ability to extend persistence units on the fly. The GlassFish Podcast has an interview up with EclipseLink's Doug Clarke. Expect more on multitenancy across the Java EE spectrum as the specification work progressed.

  • Designing rules to fight smallpox in Civ-style TBS games

    - by Williham Totland
    TL;DR: How do you design a ruleset for a Civ-style TBS game that prevents city smallpox from being a profitable or viable strategy? Long version: Civ-style games are pretty great. Bringing a civilization from cradle to grave is a great endeavor, and practicing diplomacy with hard-line human players is fun and challenging. In theory. In practice, however, many of these games has, especially in multiplayer, exactly one viable strategy: City smallpox, a.k.a. infinite city spread, a.k.a. covering all available space with 1-citizen cities, packed as tight as they will go. I suppose this could count as emergent gameplay, but still; it could hardly be considered to be in the spirit of the class of game. The Civilization series, of course, is stuck in their more or less fixed rule sets, established with Civilization. Yes, there have been major changes in some respects, but the rules pertaining to city building and maintenance have stayed pretty similar. So the question, then: If you build a ruleset for a TBS from the ground up; what rules should be in place to prevent Infinite City Sprawl from being a viable strategy? Or should ICS be a viable strategy?

  • My first time in the gambling industry

    - by sfrj
    I am a Java enterprise developer with almost 3 years of professional experience. Soon i am going to have a face to face interview with a company in the gambling industry. I already did successfully a phone screening and now for the personal interview i suppose they will ask me about some kind of white board problem or system design task. I think i am in the right place to ask about this, and would appreciate a lot if someone would give me some tips or share something related to his own experience. The things i am more interested in regarding my interview are: What are the most common challenges for programmers, in this industry? Any idea or suggestion on a white board problem they may ask me? Could you point me to some links where i can find information on the topic or sample problems in this industry?. I personally find this question very interesting not just for me. Also i think, the given answers can help also others in a similar situation. Just what i want to say whit this last comment is: Please avoid, answers like: www.google.com and so on...

  • Multi-Resolution Mobile Development

    - by user2186302
    I'm about to start development on my first game for mobile phone (I already have a flash prototype completed so it's jsut a matter of "porting" it to mobile and fixing up the code) and plan on hopefully being able to get the game working on iphones and most android devices. I am using Haxe along with OpenFL and HaxeFlixel for development. My question is: What resolution should I design the game in initially and/or what is the best way to develop a game for multiple resolutions. I have found multiple different methods, the best, in my opinion, being strategy 3 on this page: http://wiki.starling-framework.org/manual/multi-resolution_development. However I have some questions about this. First, what would the best base resolution to use be, the guide suggests 240*320 which seems alright to me, although if I chose to use pixel graphics as I most probably will given I'm using HaxeFlixel, I'm not sure if they'll look too blocky on larger screens which I'm not even sure is a problem as it might still look alright. (Honestly, not sure about that and if anyone has any examples of games that use this method and look nice). Finally, please feel free to share whatever methods you use and think is best. For example, HaxeFlixel has a scaling feature that scales the game to fit the exact screen size, but I'm afraid that would lead to blurry and improperly scaled graphics since it would scale by non-integers. But, I'm not sure how noticeable a problem that may or may not be. Although from experience I'm pretty sure it won't look nice and currently I do not think I'm going to go for this option. So, I would really appreciate any help on this subject. Thank you in advance.

  • SharePoint Saturday DC 2010 Slides, Demo Scripts, and Pictures

    - by Brian Jackett
    Wow! This past weekend I attended SharePoint Saturday Washington DC (SPSDC) which was quite an event to say the least.  For those unfamiliar, SharePoint Saturday is a community driven event where various speakers gather to present at a FREE conference on all topics related to SharePoint.  This made my fifth SharePoint Saturday attended and fourth I’ve spoken at.  SPSDC was a bit different than most SharePoint Saturdays mostly due to the scale of it.  We had almost 950 attendees, over 80 speakers presenting close to 90 sessions, and dozens of sponsors.  A big thanks goes out to the organizers of this event.  They put in a lot of hard work and time to pull this event off and should be very proud of the end result.      For SPSDC I presented “The Power of PowerShell + SharePoint 2007”.  I want to thank all of the attendees of my session for coming and asking some great questions.  Below you can find the slides and demo scripts for this session.  I also took some photos throughout the day (not as many as usual since so much going on) so check them out.  If you have any follow up questions feel free to drop me a line in the comments or the contact link at the top of the site.   Slides and Scripts Click here for the demo scripts and slides posted on my SkyDrive. VERY IMPORTANT NOTE: One thing I forgot to mention in my presentation.  In order to run code against the SharePoint API you need to load the Microsoft.SharePoint.dll assembly first.  Run the below command on the PowerShell console line to complete that:   [void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") Photos Facebook album -or- My album on Windows Live site (higher res shots).

  • ADF Essentials - Available for free and certified on GlassFish!

    - by delabassee
    If you are an Oracle customer, you are probably familiar with Oracle ADF (Application Development Framework). If you are not, ADF is, in a nutshell, a Java EE based framework that simplifies the development of enterprise applications. It is the development framework that was used, among other things, to build Oracle Fusion Applications. Oracle has just released ADF Essentials, a free to develop and deploy version of Oracle ADF's core technologies. As a good news never come alone, GlassFish 3.1.2 is now a certified container for ADF Essentials! ADF Essentials leverage core ADF features and includes: Oracle ADF Faces - a set of more than 150 JSF 2.0 rich components that simplify the creation of rich Web user interfaces (charting, data vizualization, advanced tables, drag and drop, touch gesture support, extensive windowing capabilities, etc.) Oracle ADF Controller - an extension of the JSF controller that helps build reusable process flows and provides the ability to create dynamic regions within Web pages. Oracle ADF Binding - an XML-based, meta-data abstraction layer to connect user interfaces to business services. Oracle ADF Business Components – a declaratively-configured layer that simplifies developing business services against relational databases by providing reusable components that implement common design patterns. ADF is a highly declarative framework, it has always had a very good tooling support. Visual development for Oracle ADF Essentials is provided in Oracle JDeveloper 11.1.2.3. Eclispe support is planned for a later OEPE (Oracle Enterprise Pack for Eclipse) release. Here are some relevant links to quickly learn on how to use ADF Essentials on GlassFish: Video : Oracle ADF Essentials Overview and Demo Deploying Oracle ADF Essentials Applications to Glassfish OTN : Oracle ADF Essentials Ressources

  • Non-Obvious Topics to Learn for Game Development

    - by ashes999
    I've been writing games for around 10 years now (from QBasic to C# and everything in-between). I need to start stretching my skills into different areas. What are other, surprising topics I should read up on? Expected topics would include the usual suspects: Programming language of your choice Scripting language Source control Project management (or Agile) Graphics API Maybe some AI (A* path-finding?) Physics (projectile physics) Unit testing (automated testing) I'm looking for more esoteric topics; things that you don't expect to need to know, but if you do know them, they make a difference. This could include things like: Art skills (drawing, lighting, colouring, layout, etc.) Natural language processing The physics of sound (sound-waves, doppler effect, etc.) Personally, I feel that having technical art skills (eg. can make decent art-work if you can only come up with ideas; or, following Photoshop/GIMP tutorials) was the most beneficial for me. This is not intended to be an open-ended question; I'm looking for specific skills that helped you and you expect will continue to benefit you in the short- and long-term.

  • DualLayout OpenSourceFood demo site installation instructions

    - by svdoever
    We released DualLayout which enables advanced web design with the power of SharePoint. DualLayout and a demo site can be downloaded from the DualLayout product page. This blogpost contains detailed instructions on installing the demo site. The demo site is based on the site http://opensourcefood.com. The demo site requires internet access because it still links to pages and resources of the real site. Execute the following steps to install the demo site: Copy the OpenSourceFoodDemo.zip file to your SharePoint Server 2010 Make sure that the zip file in “unblocked”, otherwise files are assumed from other computer (right-click on zip file, press “Unblock” button if available) Unzip the OpenSourceFoodDemo.zip to a folder of your choice (c:\OpenSourceFoodDemo) Open the SharePoint  Start->Microsoft SharePoint 2010 Products->SharePoint 2010 Management Shell Change directory to the unzip folder (cd c:\OpenSourceFoodDemo) Start install script: .\InstallDemoSite.ps1 Answer the questions, default values in most cases ok. A little guidance: Question: Give credentials for the account that will be used for the application pool Answer: use for example same account as used for the application pool of your SharePoint site (lookup in IIS Manager) Question: Give credentials for the account that will be used for the application pool Answer: Use same account you are currently logged in with The demo site is made available through a backup and restore. The SharePoint Server 2010 installation must be patched to a level equal or higher to the update level on the SharePoint Server used to create the backup. If you get errors with respect to restore check http://technet.microsoft.com/en-us/sharepoint/ff800847.aspx for downloading the latest cumulative update.
