before you kick off Tomcat to verify JMX, lets take a look at the above configuration.

This will popup Java Monitoring & Management Console.
This will connect to Tomcat and show you very nice graphs of CPU, Memory & Thread usage.
This becomes very handy during troubleshooting.
You may also perform GC from the console.
As mentioned at the beginning of the article, you may also configure MBeans for the classes.
