Starting from EJB 2.1, Timer Services are available for building J2EE Applications that depends on time based services. Time based services are mostly used in scheduling applications. Technically, these scheduling applications are called workflows. A workflow defines a configurable sequence of activities or tasks that will take place at a particular point of time.
