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

01:36:10,936 WARN [ClassLoaderManager] Unexpected error during load of:org.apache.jackrabbit.core.query.lucene.MatchAllWeight: java.lang.IncompatibleClassChangeError: Implementing class
[snip] 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. 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
