Thanks Jason, I am trying to know if there is way to create and register some listener to Broker so that Broker will callback some method on listener when queue becomes empty on broker. In this way, client doesn't have to poll queue to know if all messages are consumed. Well, I do also think it may not happening that Broker itself knows when queue becomes empty, then above requirement is nonsense. In this case is the polling/checking queue messages remaining is the solution?

Here's a link to at least setting up JMX on the broker with some other details http://activemq.apache.org/jmx.html .
