java.lang.Object com.sun.jdmk.comm.RmiConnectorClient
javax.management.remote.rmi
and JdmkLegacyConnector
.
public class RmiConnectorClient
Provides an implementation of the RemoteMBeanServer
interface based on the Java remote method invocation (RMI) system.
Querying a Java Dynamic Management agent with this connector implies that an instance of
RmiConnectorServer
is running on the remote Java Dynamic Management agent.
In order to identify the Java Dynamic Management agent the connector needs to communicate with,
the method connect
needs to be invoked with the
RMI identity of the RMI Connector Server
.
This class implements the ClientNotificationHandler
interface to
receive notifications from a remote MBean and the HeartBeatClientHandler
interface to detect any problem that could be encountered in the connection with the
RMI Connector Server
