package javax.management;



Represents a notification emitted by the MBean server through the MBeanServerDelegate MBean.
The MBean Server emits the following types of notifications: MBean registration, MBean
de-registration.

 To receive to MBeanServerNotifications, you need to be declared as listener to the javax.management.MBeanServerDelegate MBean that represents the MBeanServer. The ObjectName of the MBeanServerDelegate is: JMImplementation:type=MBeanServerDelegate.

Since:1.5
