Subject Re: How to check if a queue already exists
Date Thu, 05 Dec 2013 14:48:52 GMT
So the bottom line for this is simple, and Tim already mentioned this
in the other thread:

Enable security (http://activemq.apache.org/security.html) and don't
let the producer user "create" any destinations. Then allow the
consumer user to create destinations. Then you can do what you (or the
OP in the linked thread) want to do.

Though in your case, if the queue names are dynamic, how is the
producer going to know which queue to use? It can listen on advisory
messages, but does it know which destination to pick?
