I have a question. When your client (lower case) is notified that a new server has come online, are you creating a new org.jboss.remoting.Client with the new server's InvokerLocator? If not, a Client (upper case) would get confused switching between the two different protocols. If your answer is "Well, duh, of course I am", then I apologize for the question. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024800#...
