Greetings all,

I am using JBoss 3.2.5 to implement a JMS mail queue, I always get following exception:

the line in the MailConsumer() code is:
public void consume() {
try {
QueueConnection con = _factory.createQueueConnection();

_session = con.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);

QueueReceiver subscriber = _session.createReceiver(_queue);

/*line 88*/ subscriber.setMessageListener(this);
System.out.println("*************** MailConsumer:start ...****************");
con.start();
}
catch (Exception e) {
e.printStackTrace();
}
}

Could anybody tell me how to fix it, this code has been running correctly in JRun. I do appreciate for any help.

Cheers,
