Hi,

I need to write a listener class which will listen to the messages in queue. but before to tht is it required get the connection to the specified queue? If so how? as to my understanding the listener class is started when the web app is loaded and onMessage() is executed. But where shud i write the code for getting the connection? In my case the queue is already running. i only need to listen to that particular queue for getting the message and process it.

Thanks
mary

Hello Mary Anu,

I think only message producers need to get connections to the queue. In your case, you're writing a message consumer, and I think you're right. The onMessage() method will be invoked by the container when a message arrives at the queue, and this message will be passed to onMessage() as an argument of type javax.jms.Message.
