Class MBeanServer

public class MBeanServer

extends java.lang.Object

This is the base class for MBean manipulation on the agent side. It contains the necessary methods for the creation, registration, and deletion of MBeans as well as the access methods for registered MBeans. This is the core component of the JMX infrastructure.

Every MBean which is added to the MBeanServer becomes manageable: its attributes and operations become remotely accessible through the connectors/adaptors connected to that MBeanServer. An Java object cannot be registered in the MBeanServer unless it is a JMX compliant MBean.
