public void addNotificationListener (ObjectName name, NotificationListener listener, NotificationFilter filter, Object handback) throws InstanceNotFoundException IOException

Adds a listener to a registered MBean.

public void addNotificationListener (ObjectName name, ObjectName listener, NotificationFilter filter, Object handback) throws InstanceNotFoundException IOException

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.

The listener object that receives notifications is the one that is registered with the given name at the time this method is called. Even if it is subsequently unregistered, it will continue to receive notifications.

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.
- RuntimeOperationsException - Wraps an {@link IllegalArgumentException}. The MBean named by listener exists but does not implement the {@link NotificationListener} interface.
- IOException - A communication problem occurred when talking to the MBean server.

Instantiates and registers an MBean in the MBean server.

Instantiates and registers an MBean in the MBean server. The MBean server will use its Default Loader Repository to load the class of the MBean. An object name is associated to the MBean.

- MBeanException - The constructor of the MBean has thrown an exception
- NotCompliantMBeanException - This class is not a JMX compliant MBean
- RuntimeOperationsException - Wraps a java.lang.IllegalArgumentException: The className passed in parameter is null, the ObjectName passed in parameter contains a pattern or no ObjectName is specified for the MBean.
- IOException - A communication problem occurred when talking to the MBean server.
