I'm new to JMS, and would appreciate it if someone could please clear up this confusion...
There appear to be 2 ways to access a Queue object:
I've managed to get it working both ways. And I see one obvious advantage of Method 2 (queues & managers are configured through the container admin, and not inside the code).
But apart from that, are there any other important differences ? would it affect my application design or performaces ? In particular, suppose we put aside the initialization times ( assume "ctx.looup" or "session.createQueue" are called once on application startup). Will there be a difference in performance - will it take longer to send/receive JMS messages ?
