Hi, It seems I have the same issue. I'm a newer of jboss. First of all, will you please explain the word scoped? 
The second is I have the same NPE when creating a connection.
The following is my codes.

  | ConnectionFactory factory = (ConnectionFactory) ctx
  | 				.lookup("java:/JmsXA");
  | 		Destination dest = (Destination) ctx.lookup("topic/testTopic");
  | 		Connection conn = factory.createConnection();
  | 
Is this a bug of jboss?
Thank you very much.
