Paul, it is exactly what I was looking for. Is there a way to recover the examples in the link you pointed out?
To clarify better my model I should have written this link http://activemq.apache.org/how-should-i-implement-request-response-with-jms.html In relation to the comment in the page >//message to the server you would presumably want to associate the correlation ID with this >//message somehow...a Map works good I followed this example and implemented it with an association between request and response. Johan, what do you mean with 'exclusive consumers'? I'm using queues, so I'm sure that the message will be consumed only by one consumer (in opposition to topics) To tell the truth, I would prefer to implement a rejection, in other words, change the broker behavior. Anyway It is good to have a solution in the client side of the implementation.
