java.lang.Object | +--javax.jms.TopicRequestor
JMS provides a TopicRequestor helper class to simplify making service requests.
The TopicRequestor constructor is given a non-transacted TopicSession and a destination Topic. It creates a TemporaryTopic for the responses and provides a request() method that sends the request message and waits for its reply.
This is a basic request/reply abstraction that should be sufficient for most uses. JMS providers and clients are free to create more sophisticated versions
