Do you give the return call time to be called? The channel will need to
remain open for long enough after the publish. If you close the channel
immediately after the publish then you won't see output. Using your
sample code I receive this message if no consumers are present:

 [ERROR:Service :REPLY_QUEUE seems down, returning with code=313
message=NO_CONSUMERS]

and this message if the exchange is not bound to a queue:

 [ERROR:Service :REPLY_QUEUE seems down, returning with code=312
message=NO_ROUTE]
