Just a primitive Message Driven Bean doen not work!

Question

          I have a simple Message EJB and can't make it recive messages. For two days I can't
          get what's wrong - I've read already three tutorials, but... still nothing. No
          exceptions... but no messages.
          Here is it.
          all files are in attach too...
          Thank you!!!

Answer 1

Hi,
          Your sender is transacted!
          But the sender client never calls
          "session.commit()" - which is required
          to commit the work for transacted sessions.
          So the sender message never gets sent.
          If you don't want a transacted session,
          pass "false" to "createQueueSession()" rather
          than "true" and the send
          will occur immediately.
          Tom
          P.S. For more info on transacted
          sessions see the JMS FAQ and the
          JMS Programmer's Guide.
