All,
A couple months ago I had the same issue on my Ubuntu 10.10 distro. I installed 11.04 and everything went ok until now. After a deep research I realize that there were conflicts in the ports numbers , so I changed them and it works!
To change the ports go to <PROFILE_PATH>/conf/bindingservice.beans/META-INF/bindings-jboss-beans.xml
I hope this helps,
