Should run them on different mcast addresses/ports if they're on the same LAN. Re classloaders, you then need to register a context class loader for the specific region so that the unmarshalling layer knows which class loader to use when unmarshalling objects. See the chapter on the TreeCacheMarshaller in the user guide. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4026719#...
