As far as I know (and we're using EJB3overHTTP(S) really heavy) the generated EJB3-Stub sent to the client need the communication endpoint read from @RemoteBinding(clientBindUrl="xxx"), which is in fact a really bad idea, or from jboss.xml and the <client-bind-url></client-bind-url> within the <remote-binding> tag. This works for us and all our possible environments whereas are some more as 3 (probably something around 15). \sandor\ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4112125#...
