Hi all,
I'm trying to install the XWiki war file on a Ubuntu virtual machine (KVM) but as yet with no success. I've installed and configured java, jboss and mysql using all the information I could find from your website:

01:36:10,087 WARN [ClassLoaderManager] Unexpected error during load of:org.apache.jackrabbit.core.query.lucene.WildcardQuery$WildcardQueryWeight: java.lang.IncompatibleClassChangeError: Implementing class

As you can see in the error above the problem is an incompatible version. JBoss uses Jackrabbit in a given version and XWiki users another version of Jackrabbit.
It's the role of the appserver to isolate classloader so that a webapp can use whatever version it wants in WEB-INF/lib.
You need to configure JBoss to provide this isolation. You need to check Jboss's doc for that.
I just googled it quickly and found http://community.jboss.org/wiki/ClassLoadingConfiguration
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.
Hope it helps, -Vincent
Alternatively you could remove xwiki'ds jackrabbit version from WEB-INF/lib (make sure the version used by jboss is greater than the one used by xwiki).
Thanks -Vincent
Can anyone see what I'm doing wrong? All the information on the web seems a little old – I'm using JBoss 6. I would be grateful if anyone could help shed any light on this issue.
Cheers, Andy

We could... 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
