Re: Why my ACTIVEMQ_ACKS table stays empty?
We want to track the consumer applications that which message has been
consumed by which consumer while we use queues. For this purpose we use COA
and COD in WebshereMQ.
How can we achive the above required results in ActiveMQ.

You might want to add your own Broker plugin - see http://activemq.apache.org/developing-plugins.html
- to track the state of which consumer consumed which message
by all means - contribute it back! ;)
