Hi, I need to create a request/reply operation between a subscriber and a single publisher for intitalization. The publisher sends messages to topic X all the time. The subscriber first subscribes to topic X. To get additional data from the publisher a subscriber sends also a "request notification" to the publisher. I point the JMSReplyTo Header of the request to a temporary topic that should receive the reply.
I use the temporary topic and not topic X to prevent other subscribers of topic X from receiving the reply (I cannot use a selector and IDs because all are pure topic subscribers of the same topic without selectors). In fact I have now two subscribers under the same session: one for the actual topic I am interest in and one for the temproary topic for the reply. My question is: What ordering guarantees do I have for these two subscribers? If the publisher sends the notifications x1;reply;x2 will I first receive X1 with the MessageListener of my topic X subscriber and then the reply with the MessageListener of my temporary topic subscriber? Or it is also possible that I receive X1 and X2 first and then the reply? -- View this message in context: http://www.nabble.com/JMS-Request-Reply-tf3459957s2354.html#a9653565 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
