I think you are actually looking for a Terracotta server. This is a server wich can cluster JVM's (local AND over a network). They seem to support JBoss too, although they need to work on the documentation I'm afraid. I don't have any experience with the product, it's on my "long running" todo list :P You can read more on their website: http://www.terracotta.org/ this is about JBoss on their site: http://www.terracotta.org/confluence/display/docs1/Integrations+JBoss View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059581#...
