Class MbeansSource

java.lang.Object
  extended by org.apache.tomcat.util.modeler.modules.ModelerSource
      extended by org.apache.tomcat.util.modeler.modules.MbeansSource
All Implemented Interfaces:
MbeansSourceMBean

public class MbeansSource
extends ModelerSource
implements MbeansSourceMBean

This will create mbeans based on a config file. The format is an extended version of MLET. Classloading. We don't support any explicit classloader tag. A ClassLoader is just an mbean ( it can be the standard MLetMBean or a custom one ). XXX add a special attribute to reference the loader mbean, XXX figure out how to deal with private loaders
