Hola Luis, We are using RuoteAMQP for that purpose. The base implementation of RuoteAMQP will send and receive workitems over AMQP queues, as well as sending arbitrary messages (but not waiting for replies). In my case I am subclassing RuoteAMQP::Participant and RuoteAMQP::Receiver, overwriting respectively the encode_workitem and decode_workitem methods to translate between the workitem representation and my message formats and to do correlation (i.e., when an incoming message comes in, to which FEI do you assign it?). Have a look at ruote/examples/mario.rb in the Ruote sources as well as the list archives for the discussion on that.
In short, the trick is to have a Participant/Receiver pair. The Participant sends the message but doesn't do a reply_to_engine (so the workflow doesn't advance), while the Receiver does a reply when the message comes in. You could adapt this to work over JMS, XMPP PubSub or whatever other messaging platform you like. In our case we're using AMQP in one project and XMPP PubSub in another one. Hope this helps, -Mario. -- I want to change the world but they won't give me the source code.
