Glassfish v2 Cluster,HA, Load-balancing

I happen to come accross this link which explains Cluster/Load-balancing(Sun Java System Web server 7.0)/HA on Glassfish v2 in a single page. There is sample app called 'clusterjsp' which tests the cluster setup too.

Theory Info @ http://developers.sun.com/appserver/reference/techart/glassfishcluster

Setup Info @ https://glassfish.dev.java.net/javaee5/build/GlassFish_LB_Cluster.html
