Re: [xwiki-users] XWiki.war + JBoss AS6 + MySQL
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 2011-05-13 18:46:42,072 ERROR [STDERR] (RMI TCP Connection(4)-127.0.0.1) SLF4J: Class path contains multiple SLF4J bindings. 2011-05-13 18:46:42,073 ERROR [STDERR] (RMI TCP Connection(4)-127.0.0.1) SLF4J: Found binding in [vfszip:/Path-to-lib-folder-inside-our-app-ear-file/lib/slf4j-log4j12-1.6.1.jar/org/slf4j/impl/StaticLoggerBinder.class] 2011-05-13 18:46:42,073 ERROR [STDERR] (RMI TCP Connection(4)-127.0.0.1) SLF4J: Found binding in [vfszip:/JBoss5.1Home/common/lib/slf4j-jboss-logging.jar/org/slf4j/impl/StaticLoggerBinder.class] 2011-05-13 18:46:42,073 ERROR [STDERR] (RMI TCP Connection(4)-127.0.0.1) SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. 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 jboss-app loader-repository com.company:loader=MyAppName.ear loader-repository-config java2ParentDelegation=false /loader-repository-config /loader-repository /jboss-app 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-tp6309076p6369009.html Sent from the XWiki- Users mailing list archive at Nabble.com. ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users

Hi Roman, Thanks for your reply – I'll try and find out what I can but as yet can't find the tool you mention. FYI, XWiki can't use JBosses SLF4J jars and JBoss can't use XWikis SLF4J jars (or at least it breaks the web interface for the Administration console). To be honest I think it's back to the drawing board for me. Thanks to all for your help anyway.

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?

Re: [xwiki-users] XWiki.war + JBoss AS6 + MySQL
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-Log4j-to-SLF4J-Logback-tp6343910p6352403.html Regards, Roman -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-war-JBoss-AS6-MySQL-tp6309076p6356605.html Sent from the XWiki- Users mailing list archive at Nabble.com. ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users

Hi all, Please help here if you can - XWiki breaks JBoss. Could this be a library conflict? Maybe someone could suggest what jars could be causing the problem?
