JConsole is for monitoring JVMs. I’m assuming that you would like to monitor the performance of your application server. To do so, you’ll have to set the com.sun.management.jmxremote property, when initializing your application server.
For example, in Tomcat (I know this is not a complete Java EE container), you would start the container as:
You could then start JConsole as a standalone application
and then attach jconsole to the Java process that is running Tomcat. Similar steps apply to other application servers.
