Load Balancing in JMS

HI ,
I need to implement load balancing in JMS arch.

PFB the structure of my applications .

Application 1 and Application 2 are placed on different weblogic servers.

Application 3 is the common upstream for both the servers and is also placed on a different server .

The mode of comm. Between app3 –app1 and app3-app2 is JMS .

Appl3 should be uniformly distributing the requests to both the servers (appl2 and appl1) . How can this kind of load balancing implemented in weblogic 9.1 and on jms interface .

I have tried using distributed queues but they can be used on the server only . Here all the applns are on different servers .

Please help if you know the solution .

Regards,
Vaibhav
