Why not use publish/subscribe?

Pub/Sub or some other mechanism (like a distribution list) that produces one message for each process is basically the only way to do this.
Any other technically possible way will be very bad. In my opinion.
What are you really trying to accomplish? That is, why do you need two processes to get the same message?

This is application logic. You need to either put another queue in front, with a program that will filter messages onto one queue or another (or both queues using a distribution list or something), or the "first" process needs to send the necessary messages to the next queue.
You can't handle this in your MQ configuration.

Hi jefflowrey,
The logica is:
One proces put messages into a queue.(Process xx)
Another proces read from this (Process yy)
The process xx must not put some messages into the queue. it has a bug. The process xx should put the message in another queue.
My program must do a bridge (queue1 and queue2)
But Process yy read and output the message
I´ve contact wtih the developer of the process yy to ask how manage the queue
..............
.........

Okay.
So this is a very simple filter. Change the queue that XX writes to, to ZZ for instance.
Write a program that reads ZZ. If the message should be kept, then write it to YY. If the message should not be kept, then don't write it (or better yet, write it to XX.ERROR).
