Any chance the remote only accepts tcp6 connections and your local is trying to connect via the tcp4 address? I'm pretty sure the jvm default now is to "prefer IPv6" but maybe you've got some funky setting somewhere. Is there any message conveying *how* it failed, e.g. "connection refused", "invalid handshake" etc? Could there be missing classes that it's trying to resolve via rmi? No answers here but hopefully some useful questions. -tim > When attempting to connect via jconsole (as per Tomcat documentation[1]): > > $ jconsole > service:jmx:rmi://localhost:18217/jndi/rmi://localhost:18215/jmxrmi > > This command doesn't ask for username and password, and fails.
