<p>The timer service is a persistent and transactional notification service that is provided by the enterprise bean container and is used to schedule notifications or events used by enterprise beans. All enterprise beans except stateful session beans can receive notifications from the timer service. Persistent imers set by the service are not destroyed when the server is shut down or restarted.</p>
