You can publish to a pre-declared queue with /amq/queue/<name>, having 
declared the queue with a low message ttl previously over AMQP or via 
the management interface.

But if you're going to do that, you could declare an exchange that is 
not being used for anything else, and publish to that: then your 
messages will be never even hit a queue. If you don't want to have to 
declare an exchange in advance, you could use one of the built-in ones:

/exchange/amq.fanout
/exchange/amq.direct
/exchange/amq.headers

(assuming you're not using these for anything else, which you're 
presumably not)

You should probably avoid using amq.topic since that's used for 
/topic/<name> destinations in STOMP.
