The DefaultJmsReplyToEpr seems to be creating a selector based on a previous EPR selector but this seems to be unnecessary, it would appear to be sufficient just to include the jbossESBresponseUUID as the selector. Does anyone know why this was done? As for hiding it, perhaps it is sufficient to include a check for the jbossESBresponseUUID property in the DefaultJMSPropertiesSetter. In this way we could treat it in the same manner as JMSX and JMS_ properties. Kev View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4248137#...
