JMS: looking up queues ?

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 ?

Thanks very much !
I agree. Here's the link:
