Cannot create error condition

Question

Hello I am using IBM MQseries and jms to connect to the queues. Now what Im trying to do is catch linked exceptions on the read of a queue. I would start draining messages off a specific queue then in the middle close the channel, but it does not throw any exception it just halts. I am not sure if this is an error condition that is handled but i believe it should be. My class implements MessageListener
here is the bit of code that I want to handle this even
//more code
//more code
try{ //
System.out.println("Creating and starting a Connection");
connection = factory.createQueueConnection();
connection.start();
boolean transacted = false;
session = connection.createQueueSession( transacted,
Session.AUTO_ACKNOWLEDGE);
// Create a QueueReceiver and assign mesage listener
queueReceiver = session.createReceiver(queue);
queueReceiver.setMessageListener(this);
catch(JMSException e1)
if (e1.getLinkedException() == null)
e1.printStackTrace();
else
e1.printStackTrace();
System.out.println(e1.getLinkedException().getMessage());
catch(Exception ex) { ex.printStackTrace(); }
} // end of method
public void onMessage(Message msg)
String msgText = null;
counter++;
System.out.println("In onMessage fn ...");
try {
if (msg instanceof TextMessage) {
msgText = ((TextMessage)msg).getText();
System.out.println("Got TextMessage " + counter);
else if (msg instanceof ObjectMessage) {
ObjectMessage receivedMessage = (ObjectMessage) msg;
Object mess = receivedMessage.getObject();
System.out.println("Got ObjectMessage " + counter);
else { // If it is not a TextMessage...
System.out.println("Got Non-TextMessage and Non-ObjectMessage");
msgText = msg.toString();
if (msgText != null && msgText.equalsIgnoreCase("quit")) {
synchronized(this) {
quit = true;
this.notifyAll(); // Notify main thread to quit
} catch (JMSException jmse) {
if (jmse.getLinkedException() == null)
jmse.printStackTrace();
else
jmse.printStackTrace();
System.out.println(jmse.getLinkedException().getMessage());
} // end of class
Now if the channel was closed before i construct the class I would get the jms exception and the linked exception but not after. And if i open the channel up after I sptopped it nothing happens which tells me the listener is not listening
Any suggestions.
Thanks

Answer 1

but you start the connection before you associate the receiver and session to it.
if that doesn't work, maybe reboot the box. you might be running out of java virtual memory on the box. I had the same problem. It ended up being that.
