@Deprecated public interface AlarmManager extends EventSource
This can generate events. The events which can be generated are documented in the AlarmManagerEvents interface. Implement the Events interface and add an instance of this object using the AlarmManager.addListener method.
These Alarms are always executed in the same JVM as the thread that created the Alarm. The Alarms are transient and if the server fails then they are lost irrecoverably. The Scheduler should be used if a cluster wide event needs to be scheduled and needs to be guaranteed to run once in the cluster.

Alarm create(AlarmListener l, java.lang.Object context, int milliSeconds) throws java.lang.IllegalArgumentException
l- The target for the Alarm. The fired method on this is called when the alarm is fired.
context- The context object for the alarm. This is useful for supplying alarm specific data to the listener and allows one listener to be created and used for multiple alarms.

java.lang.IllegalArgumentException- This can be thrown if the async bean is an EnterpriseBean.
