Subject Re: problems using cqpid with java broker
Date Mon, 13 Feb 2012 22:20:58 GMT
Thanks to Gordon for stepping in here and helping out with the C++
client/python bindings side of things, I had admittedly missed that
point and wouldn't have had much of a clue on that front :)

On the below, it would appear that the commands you are using are
resulting in the client trying to declare an existing exchange (e.g.
amq.topic) with a different exchange type than it exists with already
(i.e not topic). I'm rather entrenched in JMS land and dont have that
good an idea of the Address Strings, but I guess I would maybe be
taking a look at the arguments you are feeding to Spout in that case.

I have updated the message of the session execution exception the Java
broker emits when this occurs to list the exchange name and the two
conflicting exchange types in question. I forced an early build of the
nightly trunk Java release job, so you should now be able to get the
updated broker artifact here if you dont want to build your own:
