I want an OSB service to act as a JMS Producer by sending messages to a consumer, say another OSB service. The consumer, upon picking up the message, should send back an acknowledgment to the OSB service (JMS explicit acknowledgment). What is the configuration required on both the sides?I'm not sure If I understood (JMS explicit acknowledgment) part of your question. Are you implying Session.CLIENT_ACKNOWLEDGE as defined below? It would be wonderful if you can detail you use-case.
