Tim - Thanks for the reply. I will try putting the McastReceiverTest.java code into an mbean and see what happens. It might be a good opinion to provide samples for UDP to JMS, SIP to JMS, and even for serial to JMS bridging in later releases. These would get outside devices such as PBX switches and other hardware talking to JBoss server. Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4108830#...
