Jconsole over VNC

Jconsole over VNC

All,
I have a remote server that I recently enabled VNC for using vnc4server
and Chicken for mac as the client.
The purpose for doing so was to enable running Java's Jconsole to monitor
an executable jar file that is running my server logic.
However, after logging into my server using VNC, I keep getting an error
when I try to use Jconsole on vnc.
It states connection failed do you want to try again. Now I am logged in
as the same user that started the process.
Is there something I am missing when using jconsole in VNC? Also can I
monitor my executable jar file remotely using Jconsole on my local
machine?
Thanks
