Hey, Sorry for the late response, I was without computer for some days. thank you all for the posts, it really helped :) After removing the distributable-tag everything works fine. And I also found how to hotdeploy during development (simply run the server in debug-mode instead of normal-mode). And now the development can be started :) Thank you :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3971871#...
