What is in your jboss-ds.xml file? You should have something like this: <datasources> | <local-tx-datasource> | <jndi-name>jdbc/XWikiDS</jndi-name> | . . . | </local-tx-datasource> | </datasource> You might also have to add a WEB-INF/jboss-web.xml file to the xwiki war file: <jboss-web> | <resource-ref> | <res-ref-name>jdbc/XWikiDS</res-ref-name> | <jndi-name>java:jdbc/XWikiDS</jndi-name> | </resource-ref> | </jboss-web> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4005517#...
