in some of the examples for published/subscriber messaging, i see the use of setJMSCorrelationID() and setClientID().  the documentation for them don't seem to be very clear.  what do they do?  and are they essential?  

i am try to create a durable subscriber, and i didn't use these two methods, and the subscriber seems to be working fine as far as getting messages that it subcribes for.

The JMSCorrelationID header field is used for linking one message with another. It typically links a reply message with its requesting message.

I don't know where you did get the setClientID() from because that method is not specified in the JMS specification.

So, in short, they are not at all essential, only there for you to make life easier.

eg. In our system we use JMSCorrelationIDs to map a message to a record in a database table. The JMSCorrelationID is passed on to several message driven beans, so the last bean in the queue can update the final state of the record in the database.
