The 0-9-1 client path (which you are using by connecting to RabbitMQ) only understands the 'BindingURL' (BURL) destination syntax, and the client defaults to using the 'Address' (ADDR) syntax. When using the "destination.<lookupName> = <destination string>" format in the properties file, if you dont specify a prefix to the destination string the client will assume it is the default, i.e ADDR. For the first, you specified a BURL prefix. For the other two examples where you didnt specify any prefix which means it used the ADDR syntax, which as mentioned earlier in the thread is why it didn't work.
You either have to specify the BURL prefix in your desintation strings, or you can change the default client-wide by setting a system property qpid.dest_syntax to the value BURL, i.e -Dqpid.dest_syntax=BURL, which would mean you wont need to specify it in the properties when using the "destination." definitions. Depending on what you are actually trying to do you could use simpler "queue." and "topic." defiitions (which are treated as BURLs) in the properties. E.g: queue.queueLookupName = queuename This would cause the client to use a (durable) queue called 'queuename' bound to the 'amq.direct' exchange with 'queuename' as the binding key. topic.topicLookupName = topicname This would cause the client to use an auto-delete temporary queue called tmp_<generated segment> bound to the 'amq.topic' exchange with 'topicname' as the binding key (which might include a subscription pattern). It is probably worth noting that the 0-9-1 client path has historically been rather fixed in its use of the amq.direct exchange for queues, and the amq.topic exchange for topics. If you still can't get things working as you would like, in order to help us advise you it would be good if you outlined what messaging topology you are actually trying to achieve.
