Debugging JConsole Connection Failed

Question

I have a web application deployed to a remote resin server, and it has JMX turned on.

I can telnet to the remote server i.e

franz@see:/tmp$ telnet &l         


        

Answer 1

if you run jconsole -debug it gives you more diagnostic info on the failure. See the Daniel Fuchs blog entry "Troubleshooting connection problems in JConsole".

I did this and it showed me I was using 32 bit jconsole the target process was started with a different (64 bit) jvm, so apparently this isn't allowed and it was thus failing.
