Loadbalance 2 jms clusters in weblogic

Hi ,
I need to load balance between 2 jms clusters in weblogic using . Each cluster url is specified as a comma separated list of host and ports like for example :,
To be more clear cluster url 1 :,
cluster url 2:,
Now how can we use the front end and backends in haproxy to load balance the jms requests across the clusters. We cannot put all the host and ports under one backend since there are other changes done in the app server to take care of messages across the nodes of the cluster ?

Could anyone provide any info on this one
