Thread: JMX and Java Application Monitoring

Beside i also want to make some changes on configuration on the fly (i mean no restart of application). All those monitoring and configuration changes should be done via web interface.

So, according to what i have found on google, i need JMX, Jetty or Tomcat and set the system up.

First, one clarification. JMX has, by itself, nothing to do with Jetty/Tomcat or in general with "application servers". If your application is a Java EE application (uses Web Components, that are JSPs/Servlets and/or EJB or other Java EE API), then it's obviously necessary to use a servlet container or (at least for EJB) a full Java EE application server.

The basic official tutorial should be sufficient to start with JMX:
