Java VisualVM does not show/list my tomcat java process

问题

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?

回答1:

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.

Our application server is JBOSS 6.1.0.final and our server itself is not starting on adding these lines to the run.conf.bat file -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=8484 -Dcom.sun.management.jmxremote.ssl=false
