Hi,
Is there a way to distinguish between message types of messages put on a queue.
For e.g.
If a Datagram message "m1" and a request message "m2" is put on queue Q1 then a receiver "R1", capable of identifying datagram messages , should retrive m1 and all datagram messages, and a receiver R2 , capable of identifying request messages should retrieve m2 and all request messages .
In short selection criteria to retrive a message should be message type.

Kindly suggest a solution.

Thanks and regards,
Lucky.

Message Type cannot be used as selection criterion for getting messages from a queue. The application could browse the messages and select them based on message type.

Better yet:
Put a process (application) that services your queue and distributes the messages according to type to different queues (1 per type)

Then you can have multiple instances of your application serving the type queue without running into performance problems due to browsing and selection etc...

Enjoy
