Subject Re: Load balancing using Queues
Date Fri, 24 Jul 2009 18:35:33 GMT

Thanks much for the response.

You mention customization via a destination policy entry.  Do you have (or
know of) example code that I could look at (i.e. somewhere in the ActiveMQ
examples)?  And how is priority set?

And another question about Queues while I've got you on the line:  As far as
I can tell, there is no way for the queue consumer to send a response back
to the producer (i.e. the process that added a message to a queue).  I'm
thinking of doing load balancing of RPC calls, where a return value
can/could be returned by the consumer.  Unless I misunderstand, this doesn't
seem possible with a single Queue.  

Thanks for any clarification.
