[jboss-user] [Messaging, JMS & JBossMQ] - Re: MDB sending a message

[n_sroor]

I use this method to start XAConnection connection:

public void startAsync(StartProcessCommand command) {
		
		if (log.isDebugEnabled()) log.debug("startAsync()");
		
		try {
			
			Destination taskProcessorQueue = (Destination)ctx.lookup("queue/ProcessManager");
			if (log.isDebugEnabled()) log.debug("Destination is: "+taskProcessorQueue+".");
			
			XAConnectionFactory factory = (XAConnectionFactory) ctx.lookup("XAConnectionFactory");
			final XAConnection cnn = factory.createXAConnection();
			final XASession session = cnn.createXASession();
			if (log.isDebugEnabled()) log.debug("Session is transacted: "+session.getTransacted()+".");
			
			cnn.start();
			
			MessageProducer producer = session.createProducer(taskProcessorQueue);
			
			Message aMessage = session.createObjectMessage(command);
			producer.send(aMessage);
			cnn.stop();
			cnn.close();
			
		}
		catch (JMSException e) {
			if (log.isErrorEnabled()) log.error("Error while talking to the ProcessManager:",e);
			// TODO do something
		}
	}


when I run it I get sometimes an Error:
