NotificationSink interface
A notification sink is a user-defined stateless session bean that is called when the task changes state.
A notification sink bean uses the following home and remote interfaces, which are defined in the deployment descriptor using an assembly tool, such as Rational Application Developer:
com.ibm.websphere.scheduler.NotificationSinkHome com.ibm.websphere.scheduler.NotificationSink
The bean itself needs to implement the handleEvent() method defined in the remote interface. For details, see the Interface NotificationSink section of the API documentation and the Receiving scheduler notifications topic.
A NotificationSink provides an event notification callback on a task-by-task basis. A notification sink is set on the TaskInfo interface, using the setNotificationSink() method. If a notification sink is not specified on a task, all notifications are lost; however, the status of a task can be determined by calling the getStatus() method from the Scheduler interface. A notification callback is made for each of the following events:
- Scheduled
- Suspended
- Resumed
- Fired
- Firing
- Fire Failed
- Complete
- Purged
