Subject RE: Detect empty Queue programmatically
Date Wed, 15 Jun 2011 17:56:46 GMT
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?

Regards,
Yuvaraj

I'm not sure if by saying "I do not want to poll the queue to see remaining
messages" means you are ruling out polling JMX also, but you could very well
monitor a Queue's QueueSize attribute via JMX and take action when it is 0.


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