JNDI lookups are working as topics. Each lookup is put on a build-in topic
called swiftmq.jndi and every router that is connected into the swiftmq
network gets this and processes it. This means that if you have two aliases
with the same name on different routers you cannot be sure that you will
get what you want.
For example:
- router1 has a JNDI alias "queue" pointing to "foo@router3"
- router2 has also a JNDI alias "queue" pointing to "foobar@router4"
- you want to get foobar@router4
- you connect to router1 and issue a JNDI lookup on "queue"
What you get is a queue, but you cannot be sure that is the right
one(foobar@router4). sometimes you get the right one and sometimes you
don't. So it is good to use different aliases on different router.
And the above goes for everything that you can lookup with JNDI. :)))
I hope this helps a bit :))
