JSM Cluster in Weblogic

When we had to deploy queues/topics in Weblogic cluster, there were two challenges, how to make the queues load balance and how to failover between nodes. Both the challenges are taken care by creating distributed queues (uniformly) and deploying to the jms servers in soa cluster (using a subdeployment module). For internal JMS clients like bpel both load-balance and failover are taken care by the server. However for external JMS clients (weblogic) we used provider url as t3://host1name,host2name:port to achieve HA and it works.
