Sending to WebSphereMQ

Question

Hi everyone,
I was hoping somebody could help me with my problem. I am new to WebSphereMQ.
I set up all the administered Objects in MQ using JMSAdmin. I am using JBoss 4.0.2 to send messages into the queue. As of now I am able to listen to the queue using an MDB but I am not able to send to the queue.
Everytime I try to send to the queue, it tries to create a new QueueManager and I get an error saying Could not create QueueManager: QM_behpr_fls0010. This queuemanager already exists. It is the default queue manager.
could somebody post some sample code or something on how to send to the queue?
here's what I have:
import java.util.Properties;
//     JMS imports
     import javax.jms.Message;
     import javax.jms.QueueConnectionFactory;
     import javax.jms.QueueConnection;
     import javax.jms.QueueSession;
     import javax.jms.QueueSender;
     import javax.jms.QueueReceiver;
     import javax.jms.Queue;
     import javax.jms.Session;
     import javax.jms.TextMessage;
     import javax.jms.JMSException;
//     JNDI imports
     import javax.naming.Context;
     import javax.naming.InitialContext;
     import java.util.Hashtable;
      * This class demonstrates a simple sender in a point-to-point
      * JMS application.
     public class Sender
        public static void main(String[] args)
           try
                 System.out.println( "Bluescope-VAI WS-QUEUE Sender started" );
                 Properties props = new Properties();
                 props.put( "java.naming.factory.initial","com.ibm.mq.jms.context.WMQInitialContextFactory");
                 props.put( "java.naming.provider.url", "QM_behpr_fls0010" );
                 InitialContext ic = new InitialContext(props);
               /** note that the queue must be defined in the $JBOSS_HOME/server/default/deploy/\jbossmq-destinations-service.xml file */
              String queueName = "RequestQueue";
              QueueConnectionFactory queueConnectionFactory = (QueueConnectionFactory)ic.lookup("WSMQQueueConnectionFactory");
              Queue queue = (Queue)ic.lookup(queueName);
                QueueConnection queueConnection = queueConnectionFactory.createQueueConnection();
                QueueSession queueSession = queueConnection.createQueueSession( false, Session.AUTO_ACKNOWLEDGE );
                QueueSender queueSender = queueSession.createSender(queue);
                // Start the connection so we can use it
                queueConnection.start();
                System.out.println( "about to send message" );
                TextMessage message = queueSession.createTextMessage();
                message.setText("This is the 1st message for Bluescope-VAI the demo " );
                queueSender.send(message);
                System.out.println( "sent message 1" );
                message = queueSession.createTextMessage();
                message.setText("This is the 2nd message for Bluescope-VAI the demo " );
                queueSender.send(message);
                System.out.println( "sent message 2" );
                queueSender.send(queueSession.createMessage());
                queueConnection.close();
                 catch( Exception e )
                    e.printStackTrace();
     }   I will appreciatae if you review this.
Thank you.

Hi,
  I have not directly faced this but i may suggest ,
1. What do you see in sxmb_moni, do you have a queue problem?
2. see this File-to-File Scenario Stopped Working  the reply from Shravan and the last message.
<i>The XBTO que was the problem. I deleted all LUWs in it and now new transactions are working again</i>
