Hi Venkatramanan, This really isn't the right forum for your question. You might try "Installation, Configuration & DEPLOYMENT" (http://www.jboss.com/index.html?module=bb&op=viewforum&f=61). The message you're seeing suggests that something other than an RMI registry is listening on port 1099. Or, alternatively, you could have a mismatched RMIClientSocketFactory / RMIServerSocketFactory pair. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4146963#...
