TemporaryQueue communication - Request/Response messaging in JMS

Question

Not able to make simple JMS application with the following steps run
Start the Server
Start the Client
The Client creates a temporary queue and sends the name to the server
Server receives message and sends a test message back.
Client NEVER receives the test message
Can someone provide me appropriate sample example in this regard. Using "oc4j_extended_101320"
Thanks

Note the server recives the request and logs the message
but client doesnt consume the message.
Here is client code

Answer 1

You created a transacted session on the server, and then never committed the transaction. Since the transaction was not committed before the session was closed, it is automatically rolled back as per the JMS spec. Either call commit on the session or use a non-transacted session (e.g., use session-creation paramters of "false, Session.AUTO_ACKNOWLEDGE").
