Personally I don't like that too much since those special container-specific files are container-specific and they're up to the admin deployer to set up. Usually admins provide their own and it really depends how they set up their appserver (there isn't a single way). The alternative is to simply document this in the install notes (or even provide the xml file as an attachment in the release notes as an example). Normally people who install WARs and who don't use the standalone version should have admin qualifications and *must* know their app server and how to configure it. Let's say I'm +0 Thanks -Vincent

Vincent and Sergiu – thanks both for all your replies. Unfortunately the headache continues. I'm not sure if this is correct but making the below changes to jboss-web.xml no longer crashes JBoss but XWiki still fails with the stack trace at the bottom of this message. “Should we create a jboss-web.xml configuration file as well?  We recently added a sun-web.xml file to fix another classloading  problem, this time for GlassFish. “ To someone like me – this seems like a great idea. Anything you can do to ease the learning curve for a newbie trying to setup and learn XWiki can't be bad.

Hi Sergiu, I still receive an error in deployment but I feel we're getting closer. Here's an update of the changes I've made and the error I now receive: ============================== In bin\run.conf.bat (if you're on windows) you should search for the  line setting Xms and MaxPermSize, and replace it with:  set "JAVA_OPTS=-Xms512M -Xmx2048M -XX:MaxPermSize=512M" ============================== I am using Linux so amended the JAVA_OPTS variable as you suggested within bin/run.conf. ============================== This is wrong, the server manages to start up because the jboss-web.xml  file is invalid, so it won't even try to start xwiki.war  Actually, since there is no real class conflict, the classloader  configuration is not important, you can remove that part completely.  ============================== Like you said, this makes no difference so I have removed this section completely. It now look like: <?xml version="1.0" encoding="UTF-8"?> <jboss-web> <resource-ref> <res-ref-name>jdbc/XWikiDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <jndi-name>java:/XWikiDS</jndi-name> </resource-ref> </jboss-web> ============================== There is another real error that occurs, and it's caused by a bad jar  file. You must solve it manually:  - locate WEB-INF/jaxb-xjc-2.1.8.jar  - delete the 1.0 directory from it (for example you can extract, delete  and repack the jar)  ============================== Here I extracted the JAR, removed the “1.0” directory and repacked the JAR as follows: jar xf jaxb-xjc-2.1.8.jar rm -vRf 1.0/ jar cvf jaxb-xjc-2.1.8.jar ./* ============================== Right now I don't get any more class loading errors, but I still have an  error about the missing data source, maybe I didn't configure it correctly:  ============================== Yeah, looks like I setup the data source wrong – the jndi name within jboss-web.xml should have been “java:/XWiki”, not “java:jdbc/XWikiDS”. Now the JBoss server starts (given enough time) but XWiki fails with the first real error being: 13:20:58,486 INFO [TomcatDeployment] deploy, ctxPath=/ 13:21:54,457 INFO [TomcatDeployment] deploy, ctxPath=/xwiki 13:21:54,657 ERROR [MbeansDescriptorsDOMSource] Error reading descriptors : java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:123) [:1.6.0_24] at org.apache.tomcat.util.DomUtil.readXml(DomUtil.java:242) [:6.0.0.Final] at org.apache.tomcat.util.modeler.modules.MbeansDescriptorsDOMSource.execute(MbeansDescriptorsDOMSource.java:86) [:6.0.0.Final] at org.apache.tomcat.util.modeler.modules.MbeansDescriptorsDOMSource.loadDescriptors(MbeansDescriptorsDOMSource.java:76) [:6.0.0.Final] at org.apache.tomcat.util.modeler.Registry.load(Registry.java:753) [:6.0.0.Final] . . .

Hi Andy, Usually class cast exceptions with JBoss indicate that you have several jars of the same library in your class path. The class looks proper but being loaded with different class loaders, it's actually different. So what you should do now is to carefully check the JBoss class path to see where do the org.apache.xerces.jaxp.DocumentBuilderFactoryImpl and javax.xml.parsers.DocumentBuilderFactory come from. I believe there's a tool (somewhere in JBoss console) that lets you see where the classes in the classpath were loaded from. Regarding your question about slf4j - most likely you did the right thing :) http://xwiki.475771.n2.nabble.com/Proposal-Switch-from-Commons-Logging-Log4… Regards, Roman -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-war-JBoss-AS6-MySQL-tp6309076p63566… Sent from the XWiki- Users mailing list archive at Nabble.com.

Hi Roman, In another thread you said: "This may not be a critical issue (in our case things worked, but we've isolated our web application's classpath and yet the warning got printed), but worth double-checking." Can I ask how you achieved classpath isolation? And what version of JBoss you are using? My attempts with adding the below section to my $JBOSS_HOME/server/default/deploy/xwiki.war/WEB-INF/jboss-web.xml appears to make no difference: <class-loading java2ClassLoadingCompliance="false"> <loader-repository> org.xwiki:archive=xwiki.war <loader-repository-config>java2ParentDelegation=false</loader-repository-config> </loader-repository> </class-loading> Cheers, Andy -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-war-JBoss-AS6-MySQL-tp6309076p63612… Sent from the XWiki- Users mailing list archive at Nabble.com.

I guess I was confusing in my statements. What I meant (or meant to mean) is that the issue might only be fixed by completely isolating the app from the JBoss class-path (or class loader), which we failed to do (warning that we still receive proves that). That is, parent class loader class-path is still visible from our application, which makes slf4j complain about multiple bindings. However, in our case we have minimized the slf4j errors to the following set and luckily it does work for us. In JBoss 7 they are going to change the class loading model and class loading configuration options, making it possible to overcome this issue (at least that's what I've heard somewhere, need a proof link). We're using JBoss 5.1 and the following code for META-INF/jboss-app.xml file of our application's ear file I don't know whether things have changed for JBoss 6 or are different for war files, so isolation config you're using might turn out to be correct as well. I wish I could help you more. If you get lucky solving this issue, please let me know :) Regards, Roman -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-war-JBoss-AS6-MySQL-tp6309076p63690… Sent from the XWiki- Users mailing list archive at Nabble.com.
