Answer 1

I would recommend Quartz

Quartz is a full-featured, open source job scheduling service that can be integrated with, or used along side virtually any Java EE or Java SE application - from the smallest stand-alone application to the largest e-commerce system. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components that may execute virtually anything you may program them to do. The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering.

Answer 2

Java EE API javax.ejb.TimedObject supports the feature.

Answer 3

I also recommend using Quartz. In case you cannot use it, don't forget the EJB 3.0 standard has the concept of EJB Timer services. You can read more here.

Answer 4

In Java you have TimerTask , you can schedule a task to run at the particular time.But i would recommend Quartz.According to your scenario , you have built in EJB Timer class available , hope will solve the purpose.
