The following means that there is no JMX server listening on the port you
configured.

It looks like you're trying to connect to Tomcat 5.0 with the JSR-160
connector. How have you configured Tomcat to publish a JMX Server? It looks
like the tomcat developers have stopped supporting the MX4J connector on
5.0 and now recommend using JDK 1.5 for the server (which has a built-in
jmx rmi server). http://issues.apache.org/bugzilla/show_bug.cgi?id=27894
