JBoss 3.0 JMS - messages not appearing in queues

[drpacman]

Hello,
I have recently installed JBoss but cannot seem to get
JMS/Message beans to work correctly. I have gone right
back to basics and tried to send messages to the example queues but still have no luck. When the code executes it appears to successfully send a message but when I check the queue depth of the receiving queue via the JNDIView MBean it is always zero. Please help! My code snippet is listed below and the output generated.

try{
...
...
// try and get a connection to MQ!
System.out.println("getting MQ factory");
javax.jms.QueueConnectionFactory factory=(javax.jms.QueueConnectionFactory)ctx.lookup("ConnectionFactory");
System.out.println("got MQ factory");

System.out.println("getting Queue connection");
javax.jms.QueueConnection qConn=factory.createQueueConnection();
System.out.println("got Queue connection");

System.out.println("getting Queue session");
javax.jms.QueueSession qSession=qConn.createQueueSession(true, javax.jms.QueueSession.CLIENT_ACKNOWLEDGE);
System.out.println("got Queue connection");

// get a handle on my queue
System.out.println("getting Queue");
javax.jms.Queue myQ=(javax.jms.Queue)ctx.lookup("queue/A");
System.out.println("got Queue - "+myQ.getQueueName());

// get handle for sender
System.out.println("getting Sender");
javax.jms.QueueSender qSender=qSession.createSender(myQ);
// make message sent persistent
qSender.setDeliveryMode(javax.jms.DeliveryMode.PERSISTENT);
qSender.setTimeToLive(10000);

System.out.println("created Sender for Q "+qSender.getQueue().getQueueName()+" and time to live="+qSender.getTimeToLive());

System.out.println("done");

// get message to fill
System.out.println("getting Message");
javax.jms.TextMessage txtMsg=qSession.createTextMessage("My Test Message");
txtMsg.setJMSExpiration(10000);
System.out.println("created Message");

// send message
System.out.println("sending Message with expiration "+txtMsg.getJMSExpiration());
qSender.send(txtMsg);
System.out.println("Sent message to "+txtMsg.getJMSDestination().toString());

qSender.close();
qConn.close();
}
catch (Exception e){...}

and the output is:

getting MQ factory

got MQ factory

getting Queue connection

got Queue connection

getting Queue session

got Queue connection

getting Queue

got Queue - A

getting Sender

created Sender for Q A and time to live=10000

done

getting Message

created Message

sending Message with expiration 10000

Sent message to QUEUE.A

Thanks
