Tricky remote JMX port problem

Tricky remote JMX port problem

2007-11-06       - By Michael B?ckling


I try using the org.apache.catalina.mbeans.JMXAdaptorLifecycleListener to
connect to the JMX service using pre-defined ports. I added the following entry
to my server.xml, and tomcat boots up ok:

<Listener className="org.apache.catalina.mbeans.JMXAdaptorLifecycleListener"
namingPort="8616" port="8617" host="localhost"/>

I'm using putty to connect to the target machine to tunnel the required ports.
And... it nearly works! The ports 8616 and 8617 on my machine are forwarded to
the remote host, so the JMX URL looks like this:


The log output of jconsole using this url is this:

06.11.2007 14:23:15 RMIConnector connect
FEINER: [ jmxServiceURL=service:jmx
:rmi://] connecting...
06.11.2007 14:23:15 RMIConnector connect

06.11.2007 14:23:58 RMIConnector connect
FEINER: [ jmxServiceURL=service:jmx
:rmi://] failed to connect: java
.rmi.ConnectException: Connection refused to host:; nested
exception is: Connection timed out: connect

Obviously, jconsole tries to connect using the wrong IP, instead
of in this case. What can I do to prevent this? Is there any

I'm thankful for any hints, I'm out of ideas... :(
