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:

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

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
