Can I run MBean under Tomcat?

We have 2 applications that work under JBoss. I am looking for a way to reduce server overhead. The main application runs under Tomcat. Another application consists of MBeans. Is there a way to run MBeans under Tomcat?

Alternative suggestions appreciated.

MBeans are part of the JMX specification that is included in the JRE. It should be possible to run MBeans under Tomcat. Tomcat 5 or later provides an MBean server.

You can use the following JVM arguments to start Tomcat with MBean enabled

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=4444 (could be anything)
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false

MBean, tomcat, - :

    // find the existing MBean server (tomcat's) in lieu of
    // creating our own
    //
    ArrayList<MBeanServer> mbservers = MBeanServerFactory
            .findMBeanServer(null);

    int nservers = mbservers.size();
    if (nservers > 0) {
        //
        // TODO: A better way to get the currently active server ?
        // For some reason, every time the webapp is reloaded there is one
        // more instance of the MBeanServer
        mbserver = (MBeanServer) mbservers.get(nservers - 1);
    }

    if (mbserver == null) {
        mbserver = MBeanServerFactory.createMBeanServer();
    }
