Hi James,
Now my Hello World works. There were two problems, first, the naming in
the XML files weren't clear to me until your mail, and after fixing that -
naming it PossessedBean :) - I had a another Exception which was due to not
including the jboss-client.jar in my CLASSPATH.
Thanks for your time, all of you.
