What about if you somehow update that xml namespace in application.xml? Since it's been a while since I wrote that example. If even that doesn't work, post this error issue on JBoss5 forum, and link it with this current thread. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4225238#...
