ActiveMQ.Advisory.MessageDiscarded.Queue

[fengcanyue <15...@qq.com>]

advisory code:   
 Destination destination =session.createQueue("test");
    Destination advisoryDestination =
AdvisorySupport.getMessageDiscardedAdvisoryTopic(destination);
    MessageConsumer consumer = session.createConsumer(advisoryDestination);
    consumer.setMessageListener(new MessageListener(){

		@Override
		public void onMessage(Message arg0) {
		}});
in the broker config code :
  policyEntry.setAdvisoryForDiscardingMessages(true);


I hope to get notification when message is discarded.but i cannot get any
message.
I want to know consumer will  get a discardmessage under what circumstances.

thanks!

I believe that the discarded message count in JMX is incremented (and so
I'd expect an advisory message to be generated, though I've never looked
for one to confirm that) when a message expires while still on the broker.
(I believe I've observed that if the message expires after being dispatched
to the consumer but before being consumed, the count doesn't increment and
I'd expect no advisory message is generated.)  There may be other
circumstances as well.
