Aside from how, why? What's the requirement for a subscriber not to subscribe via topic name? How will the subscriber know the correl id it needs to subscribe to?
More information, better answers.

This is an enhancement of the pub /sub..since the docs says we con do using correID we are investigating on how to do it.
cause there could be some application reads via jms..etc where we cant define the topic names..
i found something , in the RFHUTIL, the option CorrelAsId under the pub/sub tab when adding a sunscriber....how do i use that optin..any kind of help is appriciated..
Thanks

AFAIK the correlId is used to distinguish one subscriber from another when retrieving the message from the common publish destination.
It may not be very relevant if the subscriber specified it's own destination for the topic(s) he subscribed to.

Yes ..thats right i tested and came to a final decision that we cant subscribe using only correlId , we need either Topic Name or Subscription Point and correlId can be used to sunscribe as an added filter . so we can differentitate the messages ..
