How does a consumer acknowledge a message from a producer?

The easiest way is to allow the framework to do it--automatic acknowledgment:
... topicCon.createTopicSession(false, AUTO_ACKNOWLEDGE); ...
With client acknowledgment, a client can allow messages to accumulate until some arbitrary application condition:
... topicCon.createTopicSession(false, CLIENT_ACKNOWLEDGE); ...
When a client acknowledges a message, the acknowledged message and all "older" messages become unavailable for future processing.
