    Send JMSMessage - JBoss ESB Ignoring MapMessage, returning n

    ezani abdul halim Newbie

      Hi there

      I am just going through the quickstart Helloworld JBossESB samples, particularly the Helloworld and the Helloworld JMS Router example. The original sample used a TextMessage type and a String as the message payload. I then played with the code and tried sending a streamable Java object (a JPA Entity) as an ObjectMessage and it worked and sent and was received successfully at the other end. I then changed to a MapMessage with the same example but I am now getting a 'Message type SpyMapMessage not supported - Message is ignored' warning and returns a null object and I am unable to read the message payload at the other end.

      Warning I am getting:

      10:19:32,812 WARN [PackageJmsMessageContents] Message type SpyMapMessage not supported - Message is ignored
      10:19:32,812 WARN [JmsGatewayListener] Action class method <process> returned a null object
      


      Why is it then when I change the sample example to a MapMessage, the listener appears to fail to detect and print it out to console?

      Here's my SendJMSMessage.java:

      
      package org.jboss.soa.esb.samples.quickstart.jmsrouter.test;

       System.out.println("");
       producer.close();
       }
      
       public void receiveAMessage() throws JMSException {
      
       MessageConsumer consumer = session.createConsumer(responseDestination, "JMSCorrelationID = '" + correlationId + "'");
       Message jmsMsg = consumer.receive();
      
       System.out.println("Received from " + responseDestination + ":");

       }

       }
      
      
       public static void main(String args[]) throws Exception
       {
       SendJMSMessage sm = new SendJMSMessage();
       //sm.setupConnection(args[1]);

       sm.stop();
       }
      
      }
      
      


      and here's MYJMSListenerAction.java:

      package org.jboss.soa.esb.samples.quickstart.jmsrouter.listener;

      public class MyJMSListenerAction implements MessageListener {
      
      
       public void onMessage(Message message) {
      
       MapMessage msg = (MapMessage) message;
      
       try {
      
       System.out.println("MyJMSListenerAction detected message on queue...");
       System.out.println("Bidder Id : " + msg.getString("BidderId"));
       System.out.println("Bidder Session Id : " + msg.getString("BidderSessionId"));
       System.out.println("Bidder Name : " + msg.getString("BidderName"));
      
      
       } catch (JMSException je) {
      
       System.out.println("MyJMSListenerAction - onMessage() - Exception: " + je.toString());
      
       }
      
      
       }
      
      }
