I give thought to the correlation ID concept on the JMS Specification. When using synchronous queue messages, we should have JMSReplyTo header which has a destination of the producer.
After sending, the producer waits for reply message to reach its temporary queue. In this format, it is only the consumer of that message that can send the reply message by JMSReplyTo header. So it's fine without correlation ID because the producer waits for reply message not on the static queue but on the temporary queue registered in the JMSReplyTo header. And that's all in my thought. Then, What's the purposes for using the correlation ID? I have heard that using this is for relating sending message to its reply message. But it doesn't need to relate between them unless we using it in the application layer. Although it's not about activemq, I try asking because I can't find any appropriate forum for that issue. I hope anybody informs me of this concept. regards, sic -- View this message in context: http://old.nabble.com/correlation-ID-on-synchronous-message-tp29105526p29105526.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
