Howto determine if a JMS queue exists before using it

[hughbragg]

Is there a way to quickly determine if a JMS queue exists before attempting to send/receive on it?

I have a program which follows the examples, but they all create a queue in ste 1 before connecting:

Queue queue = HornetQJMSClient.createQueue(cfg.JMS_QUEUE);

If I do this then I follow the rest of the example create a session, connect, start everything runs smoothly.

If I missname the queue on the server the client doesn't complain until it tries to send or receive a message.

That's a problem as I have a socket open which is expecting a response and the exception causes it to hang.

I can rewrite the socket to catch the exception, but I'd be much happier if I could determine if the queue exists when I startup. That way I can issue a warning when something isn't right.

There are several ways you can do this in HQ, e.g. using the management API.

However, the portable JMS way to do this would be to attempt to create a consumer on the queue and catch any exception thrown.

Thank you very much. This works for a producer as well.
