I have deployed the same packages as you and they are working fine. I can think off two possibilities why this may happen to you. First is that ForumsModule MBean didn't deploy properly. You should see this in log at the end of starting AS. Second is that you may have some errors in your database. Like having topics without any posts what could cause similar efect. Nevertheless, check AS logs. It should give you some clue. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3960941#...
