Hi, I'm afraid you didn't use setClientID correctly. Please see the following API doc: anonymous wrote : | If a client sets the client identifier explicitly, it must do so immediately after it creates the connection and before any other action on the connection is taken. After this point, setting the client identifier is a programming error that should throw an IllegalStateException. | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4238945#...
