public abstract class CommandMBean

implements MBeanRegistration

The superclass for all services that are to be deployed as MBeans. This class itself is not a valid MBean - there is no MBean interface. Subclasses need to provide their own MBean interface. This class simply provides some convienent lifecycle methods.
