Interface PersistencePolicy

public interface PersistencePolicy

Timers are persistent objects. In the event of a container crash, any single-event timers that have expired during the intervening time before container restart must cause the ejbTimeout method to be invoked upon restart. Any interval timers that have expired during the intervening time must cause the ejb- Timeout method to be invoked at least once upon restart.
