Class GenericHttpConnectorClient

java.lang.Object
  com.sun.jdmk.comm.GenericHttpConnectorClient

All Implemented Interfaces:

ClientNotificationHandler, HeartBeatClientHandler, RemoteMBeanServer, NotificationRegistration, ProxyHandler, Serializable

Direct Known Subclasses:

HttpConnectorClient, HttpsConnectorClient

Deprecated. The JMX Remote API should be used in preference to the legacy Java DMK connector classes. This class may be removed in a future version of Java DMK. See JdmkLegacyConnector.

public abstract class GenericHttpConnectorClient
extends Object
implements RemoteMBeanServer, HeartBeatClientHandler, Serializable

The GenericHttpConnectorClient class provides an implementation of the RemoteMBeanServer interface based on the HTTP protocol.

Querying a Java Dynamic Management agent with the HTTP connector implies that an instance of GenericHttpConnectorServer 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.

It is possible to request the use of a specific proxy through the java properties http.proxyHost=host and http.proxyPort=port for HTTP, and https.proxyHost=host and https.proxyPort=port for HTTPS.

The authentication information required to configure the connector is provided by the ConnectorAddress parameter in the method connect.

The following port numbers are used by default:

• 8081 for the HTTP/TCP connector
• 8084 for the HTTP/SSL connector

This class implements the ClientNotificationHandler interface to receive notifications from a remote MBean, and the HeartBeatClientHandler interface to be able to detect any communication problem with the connector server and notify it to the manager that created it.

Constructor Detail

GenericHttpConnectorClient

public GenericHttpConnectorClient()

Deprecated.

Constructs a connector client.

This constructor will send the default local host name to a server for receiving notifications.

GenericHttpConnectorClient

public GenericHttpConnectorClient(InetAddress addr)

Deprecated.

Constructs a connector client.

Parameters:

addr - local address sent to a server for receiving notifications. This address will be saved internally using InetAddress.getHostAddress.

Method Detail

setOperationContext

public void setOperationContext(OperationContext c)

Deprecated.

Set the OperationContext of this connector. This context will be sent along with each request and can be recovered by the server, which can make it available to the operations it invokes.

The saved OperationContext will be a clone of the object c made using its clone method.

Specified by:

setOperationContext in interface RemoteMBeanServer

Parameters:

c - the new OperationContext. It may be null to indicate that there is no context. The previous OperationContext, if any, is lost.

Throws:

CommunicationException - if the context cannot be set for some reason. One common reason is that the object c does not implement the Cloneable interface.

getOperationContext

public OperationContext getOperationContext()

Deprecated.

Get the OperationContext that was last given to setOperationContext, or null if setOperationContext was never called.

Specified by:

getOperationContext in interface RemoteMBeanServer

Returns:

All the information needed for identifying the MBeanServer to contact and the protocol to be used is contained in the object of type ConnectorAddress passed as a parameter. If a communication problem occurs this method will throw a CommunicationException (JMRuntimeException). If the RemoteMBeanServer had already been connected to and disconnected from an MBeanServer identified by its MBeanServerId, and if the MBeanServer reachable by the MBeanServerAddress parameter doesn't have the same MBeanServerId, then java.lang.IllegalAccessException is thrown.

Specified by:

Parameters:

mbeanServerAddress - The address for the MBeanServer to contact (MBeanServer identification, protocol specification).

Returns:

A String identifying the MBeanServer with which the communication is established.
