  +--com.ibm.websphere.management.configservice.ConfigServiceProxy
All Implemented Interfaces:
ConfigService
public class ConfigServiceProxy
extends java.lang.Object
implements ConfigService

This class implements a proxy object of the remote ConfigService MBean in the server. As config service is implemented as a MBean in the server, all the method calls on the MBean have to go through invoke method which is cumbersome and error prone. This the a helper class to allow user using remote config service component more easily.
