• Is OpenGL 1.x deprecated?

  - by QuasarDonkey

  I'm familiar with OpenGL 1.x. I typically use SDL with OpenGL 1.4 on Linux, and I've never run into problems, even on my modern system. I've read on the OpenGL site about deprecation and compatibility contexts, but I'm still unclear as to whether it's safe to continue to use old versions of OpenGL, as opposed to using old features in newer versions. When functionality is marked deprecated ... future versions of OpenGL may remove it. Does deprecation simply imply that those functions can't be used alongside newer features? More specifically, are there any systems today (other than embedded) where OpenGL 1.x isn't available? The old-skool stuff like, glBegin, glEnd, glDrawPixels, etc. Note: I'm not a professional games developer, so you'll have to excuse my ignorance. I'm working on a mostly 2D game that I would like to keep multi-platform, supporting at least Linux, Mac, and Windows.

• YouSendIt Alternative?

  - by user4855

  Looking for a reasonably priced alternative to YouSendIt's exorbitant pricing for an embedded, unbranded (i.e. no "Uploads by SomeCompany" or at the very least, discrete, subtle co-branding) file upload solution for my client's print shop Website. To do what we want to do with YouSendIt, we're looking at a corporate account of $995 USD plus $29.99 USD monthly fee, that is only sold pro-rated, so you have to buy the entire year's worth. To me, this is just unacceptable considering the commodity pricing of storage and bandwidth nowadays. For data, we're looking at roughly 10MB per upload, with perhaps 250-1000 uploads per month, with transient data storage of no more than 30 days (and more than likely 1-2 business days) for a total of 10 GB transfer (upload) and 10 GB transfer (download, to the print shop) at the very max each month. Any ideas? Everything I've found through searching seems to be geared more towards personal file sharing and not for embedding into Websites. Thanks

• Synchronizing (updating) published files

  - by MucMug

  How can I update a published file and maintain the same URL? After saving an update of a published file on my desktop, it will automatically "synchronise" with the corresponding files at UbuntuOne (and it does). Problem is that the "new file", actually the updated file with the same name, is no longer published. Pressing the publish button results is a new URL. I now have to mail new URL's and change embedded links, as old URL will result in a failure to find the updated file (or indeed any file). I am not sure if it is a bug or a design flaw (maybe intentional?), but it seems strange to me.

• Apache Solr: Setting HTTP Response Headers From solrconfig.xml For CORS

  - by Noah Freitas

  Is it possible to setup the sending of a custom HTTP response header from within the solrconfig.xml file? I am thinking that it might be possible to add some configuration to the <requestDispatcher> since it controls caching headers. I am sure this is possible in the servlet container configuration (Jetty, Tomcat, etc.), but I would like to do this from within Solr's configuration files if at all possible. If this makes any difference, I am attempting to set an Access-Control-Allow-Origin header for CORS AJAX requests for a different host.

• Middleware for MongoDB or CouchDB with jQuery Ajax/JSON frontend

  - by Tauren

  I've been using the following web development stack for a few years: java/spring/hibernate/mysql/jetty/wicket/jquery For certain requirements, I'm considering switching to a NoSQL datastore with an AJAX frontend. I would probably build the frontend with jQuery and communicate with the web application middleware using JSON. I'm leaning toward MongoDB because of more dynamic query capabilities, but am still considering CouchDB. I'm not sure what to use in the middle. Probably something RESTful? My preference is to stick with Java (or maybe Scala or Groovy) since I'm using tools like Drools for rules and Shiro for security. But then again, I want to pick something that is quick an easy to work with, so I'm open to other solutions. If you are building ajax/json/nosql solutions, I'd like to hear details about what tools you are using and any pros/cons you've found to using them. Thanks!

• Automatically tidy up JSP/JSF files

  - by er4z0r

  Hi, I am working on a webapplication and I do most of the XHTML stuff in an editor. Every once in a while I froget to close a tag or mess up the nesting (we all get distracted sometimes ;-)). So I commpile, package and run my webapp (using maven mvn clean package jetty:run-war only to notice that displaying the view (where I messed up the jsp) fails with an exception while trying to render. So I wondered: Is there some tool that I can include into my build-cycle that automatically catches and rectifies those careless mistakes?

• CSS Files Don't Refresh with Wicket (Launched in Intellij via Start.java)

  - by Scanningcrew

  I have create a skeleton Wicket project using mvn archetype:create -DarchetypeGroupId=org.apache.wicket -DarchetypeArtifactId=wicket-archetype-quickstart -DarchetypeVersion=1.4-rc4 -DgroupId=com.mycompany -DartifactId=myproject All the configuration/importing new project with Maven/Intellij worked fine. I proceeded to add a basic CSS file to my start page, per the following recommended way of doing it in Wicket 1.4 public class BasePage extends WebPage { public BasePage() { add(CSSPackageResource.getHeaderContribution(BasePage.class, "main.css")); } } The main.css file has been put along side BasePage.java and BasePage.html in /src/main/java. I launch the application with Start.java. The problem is when I make changes to the CSS file it is not being picked up when I relaunch Start.java. (Changes to the java and html files are being updated when I change them) I made sure the browser cache was being cleared, and even valided the request/response in Firfox/Firebug. It seems like somewhere between Wicket's magic and the jetty instance Start.java creates the CSS file is being cached and not updated. Any ideas?

• How do I set the jax-ws client request timeout programatically on jboss?

  - by Jonas Andersson

  I am trying to set the request (and connection) timeout for a jax-ws-webservice-client generated with the jaxws-maven-plugin. When running my app under tomcat or jetty the timeout works, but when deployed under jboss it doesn't "take". private void setRequestAndConnectionTimeout(Object wsPort) { String REQUEST_TIMEOUT = BindingProviderProperties.REQUEST_TIMEOUT; // "com.sun.xml.ws.request.timeout"; ((BindingProvider) wsPort).getRequestContext().put(REQUEST_TIMEOUT, timeoutInMillisecs); ((BindingProvider) wsPort).getRequestContext().put(JAXWSProperties.CONNECT_TIMEOUT, timeoutInMillisecs); } What is the correct way to do this for JBoss?

• JPA 2.0 Implementations comparison : Hibernate 3.5 vs EclipseLink 2 vs OpenJPA 2

  - by peperg

  What's your choice? Do You have any suggestions and experience? I'm developing an application with Hibernate 3.5 and Spring 3.0 Pros: Good documentation Easy configuration and helpful logs Popularity - wide community Some extensions to JPA Some additional Tools - JBoss Tools for Eclipse, hbm2ddl, generating static metamodel etc... Cons: Bugs! (Sequences, collections etc...) Lots of reatures are doubled with "pure" Hibernate. There's a mess in legacy Hibernate and JPA annotations. I'm considering to switch to EclipseLink. What do You think ? Edit: I've tried EclipseLink and have very bad experiences. It seems like EclipseLink needs LoadTimeWeaver and likes to run on OSGi platform rather than simple Jetty or Tomcat environment. I just don't have time for all this configuration stuff.

• Out of Memory - web applications

  - by Walter White

  Hi all, I am trying to figure out why Jetty 6.1.22 is running out of memory on my laptop. I have 2 web applications running JBoss Seam, Hibernate (with EHCache), and separate Quartz scheduler instances. With little load, the server dies throwing OutOfMemory. What can I look for? Would you think that I am not properly closing handles for input streams or files? I tried profiling my application with Netbeans, but it works off and on. Usually, it ends up locking up even though it doesn't use that much CPU or memory. Walter

• How to find the physical path of a GSP file in a deployed grails application

  - by Deepak Mittal

  I need to find out the physical path of a grails GSP file. My requirement is that I want to create a new layout file at run-time and use that in the application. I have been able to achieve this without problem when the application runs on jetty (grails run-app), however, when I deploy the app on Jboss, the path at which the file needs to be created changes. So, ideally I would like to find out at runtime using some magical utility the path of a particular GSP (lets say main.gsp layout file) and I need to create my new layout in the same directory in which main.gsp reside. Any pointers? -Deepak

• Beginning GWT and Java - wich is the best route when coming from LAMP background?

  - by Cambiata

  Hi! I've worked a lot with php/mysql on linux servers, including frameworks, orm etc. Now I want to give GWT and Java a try! Installing GWT SDK, Eclipse plugin etc and running a "Hello world" is no problem... The server is running automagically in the background... But when it comes to setting it up my self, there seems to be confusingly many options. Jetty? Tomcat? Glassfish? How are those related/combinable to/with Apache? Are there any good resources or tutorials for setting up java development and server environments suited for one like me with PHP background? Maybe pointing out the possiblities of running PHP and Java on the same server? Regards / Jonas

• ClassCastException happens when I use maven with tomcat plugin

  Hi all, I try to use maven with tomcat plugin to develop a simple web application. But When I invoke the servlet, ClassCastException happens, this is the error message: java.lang.ClassCastException: "com.snda.dw.moniter.LogQueryServlet cannot be to javax.servlet.Servlet" But I already make com.snda.dw.moniter.LogQueryServlet extends HttpServlet, it should can be cast to avax.servlet.Servlet. The following is my pom.xml http://maven.apache.org/maven-v4_0_0.xsd" 4.0.0 com.snda dw.moniter war 0.0.1-SNAPSHOT dw.moniter Maven Webapp http://maven.apache.org junit junit 3.8.1 test <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.4</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>r07</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.6.1</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-simple</artifactId> <version>1.6.1</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-core</artifactId> <version>0.20.2</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>com.snda</groupId> <artifactId>dw.common</artifactId> <version>1.0-SNAPSHOT</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>net.sf.flexjson</groupId> <artifactId>flexjson</artifactId> <version>2.1</version> <type>jar</type> <scope>compile</scope> </dependency> </dependencies> <build> <finalName>dw.moniter</finalName> <pluginManagement> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>tomcat-maven-plugin</artifactId> <version>1.1</version> </plugin> <plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>8.0.0.M2</version> </plugin> </plugins> </pluginManagement> </build>

• Should integration testing of DAOs be done in an application server?

  - by HDave

  I have a three tier application under development and am creating integration tests for DAOs in the persistence layer. When the application runs in Websphere or JBoss I expect to use the connection pooling and transaction manager of those application servers. When the application runs in Tomcat or Jetty, we'll be using C3P0 for pooling and Atomikos for transactions. Because of these different subsystems, should the DAO's be tested in a fully configured application server environment or should we handle those concerns when integration testing the service layer? Currently we plan on setting up a simple JDBC data source with non-JTA (i.e. resource-local) transactions for DAO integration testing, thus no application server is involved....but this leaves me wondering about environmental problems we won't uncover.

• load-views when running multiple noir servers

  - by Roth Michaels

  I'm experimenting with using noir to start three servers (each to handle a different aspect of the application). I am trying to do this so that I can run all three servers within one application while developing and easily decouple the project into three different applications for deployment. It is no problem to use noir.server/start and noir.server/stop to run the jetty servers I need. What I'm trying to figure out is some way to call load-views (or something like that) with a different set views for each server so that URI conflicts are handled by the correct defpage.
