Claus, thanks for the quick reply. I did it some tests and it seems to work, but can you help me understand what is really happening behind the scenes?
Looking at the camel code, it will add a header to the JMS message using a unique ID (generated by camel) as a value and the name I gave as the header key (which will be used by the selector to retrieve replies from the shared queue, so that particular JVM will only get replies for that endpoint/selector). Thus each running camel instance will be able to retrieve the replies exactly for the messages they produced, and Camel will still be able to return them to the respective producers, based on the original JMSCorrelationID they set, is that correct?
