Request/Reply w/ MDB

Question

I'm having some trouble with my request/reply setup.
          Here's the requesting code (just a regular test class):
          String request = "<mileage-xml-request><origin><city>UNIONTOWN</city>" +
          "<state>OH</state><zip>44685</zip><country>USA</country></origin><dest><city
          >DALAS</city>" +
          "<state>TX</state><zip>75201</zip><country>USA</country></dest></mileage-xml
          -request>";
          String initialContextFactory =
          "com.tibco.tibjms.naming.TibjmsInitialContextFactory";
          String providerURL = "tcp://app-dev-01.blue.fedex.com:7222";
          QueueConnectionFactory factory = (QueueConnectionFactory)
          JndiHelper.lookup("QueueConnectionFactory", providerURL,
          initialContextFactory);
          QueueConnection conn = factory.createQueueConnection();
          QueueSession session = conn.createQueueSession(false,
          Session.DUPS_OK_ACKNOWLEDGE);
          Queue queue = (Queue) JndiHelper.lookup("COM.FEDEX.BLUE.MILEAGE.REQUEST",
          providerURL, initialContextFactory);
          QueueRequestor requestor = new QueueRequestor(session, queue);
          TextMessage requestMessage = session.createTextMessage(request);
          TextMessage textMessage = (TextMessage) requestor.request(requestMessage);
          System.out.println(textMessage.getText());
          requestor.close();
          session.close();
          conn.close();
          And the reply code (inside my MDB, called from onMessage):
          Queue queue = (Queue) message.getJMSReplyTo();
          QueueConnectionFactory factory = (QueueConnectionFactory)
          JndiHelper.lookup("QueueConnectionFactory", providerURL,
          initialContextFactory);
          QueueConnection conn = factory.createQueueConnection();
          QueueSession session = conn.createQueueSession(false,
          Session.DUPS_OK_ACKNOWLEDGE);
          QueueSender sender = session.createSender(queue);
          TextMessage replyMessage = session.createTextMessage(reply);
          replyMessage.setJMSCorrelationID(correlationID);
          sender.send(replyMessage);
          sender.close();
          session.close();
          conn.close();
          The requesting code runs fine up to
          TextMessage textMessage = (TextMessage) requestor.request(requestMessage);
          Which then triggers the reply code, which runs to completion, but the reques
          tor never receives a reply.
          Any ideas on what to try next? Is my requestor listening on the wrong queue
          for the answer? Is my replier sending to the wrong queue?
          Thanks.
          Eric
          

Answer 1

I just needed
          conn.start();
          after
          QueueRequestor requestor = new QueueRequestor(session, queue);
