And a more simple approach would be to use the

org.apache.activemq.advisory.ConsumerEventSource class and let it
notify your implementation of the ConsumerListener class with
ConsumerStartedEvent and ConsumerStoppedEvent objects.

Himmeric,

The consumer advisory topic will let you know when consumer come
online and also offline.  You could maintain a reference counter and
when it dops to zero, you would know there no active consumers on the
topic.

The message sent on the topic when a consumer goes offline is of type
RemoveInfo.
