The MBean Server Implementation and Factory

The MBeanServerImpl class in the Java Dynamic Management Kit implements the MBeanServer interface. It is the class that will be instantiated in an agent. However, it is never instantiated directly by the agent application. Instead, you rely on the MBean server factory to return a new instance of the implementing class.

The MBeanServerFactory is a static class defined by the Java Management extensions that makes the agent application independent of the MBean server implementation. It resides in the Java virtual machine and centralizes all MBean server instantiation. It provides two static methods:

• createMBeanServer which returns a new MBean server instance

• findMBeanServer which returns a list of MBean servers in the Java virtual machine

You must use this class to create an MBean server so that other objects can obtain its reference by calling the findMBeanServer method. This method allows dynamically loaded objects to find the MBean server in an agent which has already been launched.
