Java VisualVM does not show/list my tomcat java process

I am using jdk64 and my java version is 1.6.0_24. I am running both (Tomcat java process and VisualVM) processes as Administrator on Windows Server 2008.

Tomcat is running with -Xmx7196m, where as jvisualvm is running with -Xms24m and -Xmx256m. Could this be the cause?

Answer

You need to add the JMX parameters to enable the JMX connection to your application, so add the following parameters:

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.port=8484
-Dcom.sun.management.jmxremote.ssl=false

Then You need to add your tomcat process manually, So right click on you localhost node -> Add JMX Connection -> type your port -> OK.

Your tomcat process will be listed in under localhost node.
