Figure 5.2 A Dynamic MBean managing a Jini service. The service creates the MBean when it is
initialized and removes the MBean as it is shut down. The MBean can be used to change the service's
description to the world by adding/removing Jini
Entry
objects.
A good place to begin Jini service management via an MBean is its set of
Entry
objects, which describe the service. You want to be able to add, modify, or delete
Entry
attributes at runtime in order to describe the Jini service in a different way.
By changing the
Entry
objects, you change the way clients discover the Jini ser-
vice. The following is the
ManagedJINIService
interface:
package jmxbook.ch5;
import java.rmi.*;
import java.util.*;
public interface ManagedJINIService extends Remote
{
public void addEntries( Vector entry ) throws RemoteException;
public void modifyEntries( Vector oldEntries, Vector newEntries )
throws RemoteException;
}
