Interface MBeanServer

All Superinterfaces:
MBeanServerConnection
All Known Subinterfaces:
MBeanServerForwarder

public interface MBeanServer
extends MBeanServerConnection

This is the interface for MBean manipulation on the agent side. It contains the methods necessary for the creation, registration, and deletion of MBeans as well as the access methods for registered MBeans. This is the core component of the JMX infrastructure.

User code does not usually implement this interface. Instead, an object that implements this interface is obtained with one of the methods in the MBeanServerFactory class.

Every MBean which is added to the MBean server becomes manageable: its attributes and operations become remotely accessible through the connectors/adaptors connected to that MBean server. A Java object cannot be registered in the MBean server unless it is a JMX compliant MBean.

When an MBean is registered or unregistered in the MBean server a MBeanServerNotification Notification is emitted. To register an object as listener to MBeanServerNotifications you should call the MBean server method addNotificationListener with ObjectName the ObjectName of the MBeanServerDelegate. This ObjectName is:
JMImplementation:type=MBeanServerDelegate.

An object obtained from the createMBeanServer or newMBeanServer methods of the MBeanServerFactory class applies security checks to its methods, as follows.

First, if there is no security manager (System.getSecurityManager() is null), then an implementation of this interface is free not to make any checks.

Assuming that there is a security manager, or that the implementation chooses to make checks anyway, the checks are made as detailed below. In what follows, className is the string returned by MBeanInfo.getClassName() for the target MBean.

If a security check fails, the method throws SecurityException.

For methods that can throw InstanceNotFoundException, this exception is thrown for a non-existent MBean, regardless of permissions. This is because a non-existent MBean has no className.

Parameters:
className - The class name of the MBean to be instantiated.
name - The object name of the MBean. May be null.
Returns:
An ObjectInstance, containing the ObjectName and the Java class name of the newly instantiated MBean. If the contained ObjectName is n, the contained Java class name is getMBeanInfo(n).getClassName().
Throws:
ReflectionException - Wraps a java.lang.ClassNotFoundException or a java.lang.Exception that occurred when trying to invoke the MBean's constructor.

                             throws InstanceNotFoundException
Description copied from interface: MBeanServerConnection

Adds a listener to a registered MBean.

A notification emitted by an MBean will be forwarded by the MBeanServer to the listener. If the source of the notification is a reference to an MBean object, the MBean server will replace it by that MBean's ObjectName. Otherwise the source is unchanged.

Specified by:
addNotificationListener in interface MBeanServerConnection
Parameters:
name - The name of the MBean on which the listener should be added.
listener - The listener object which will handle the notifications emitted by the registered MBean.
filter - The filter object. If filter is null, no filtering will be performed before handling notifications.
handback - The context to be sent to the listener when a notification is emitted.
Throws:
InstanceNotFoundException - The MBean name provided does not match any of the registered MBeans.

Description copied from interface: MBeanServerConnection

Adds a listener to a registered MBean.

A notification emitted by an MBean will be forwarded by the MBeanServer to the listener. If the source of the notification is a reference to an MBean object, the MBean server will replace it by that MBean's ObjectName. Otherwise the source is unchanged.

Specified by:
addNotificationListener in interface MBeanServerConnection
Parameters:
name - The name of the MBean on which the listener should be added.
listener - The object name of the listener which will handle the notifications emitted by the registered MBean.
filter - The filter object. If filter is null, no filtering will be performed before handling notifications.
handback - The context to be sent to the listener when a notification is emitted.
Throws:
InstanceNotFoundException - The MBean name of the notification listener or of the notification broadcaster does not match any of the registered MBeans.
