Depends upon what you want to load balance and what you mean by "clustering". If all you want to do is load balance webapp requests between a bunch of servers, and you don't need to replicate HTTP session state (i.e. you don't care if the user's session is lost if they fail over from one server to another), then you don't need to use any of JBoss AS's clustering features -- you can just run the default config. Otherwise, you need the AS clustering features. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966241#...
