postRegister

public final void postRegister(Boolean registrationDone)
Last steps to be done after MBean is registered on MBeanServer. This method is made final because it contains vital steps mandatory to all J2EEManagedObjects. To perform your own Post-Creation steps please override postCreation() method.

Specified by:
postRegister in interface javax.management.MBeanRegistration

preDeregister

public final void preDeregister()
                         throws Exception

Throws:
Exception

sendNotification

public void sendNotification(String type,
                             String info)
An overload of the super sendNotification that only takes the event type and msg. The source will be set to the managed object name, the sequence will be the getNextNotificationSequenceNumber() value, and the timestamp System.currentTimeMillis().

Parameters:
type - the notification event type
info - the notification event msg info

toString

public String toString()

postCreation

protected void postCreation()

preDestruction

protected void preDestruction()
