Sample of a Stateless Session Bean in EJB 3.0

This sample will demonstrate the following new features from EJB 3.0

1. Elimination of the requirement for EJB component interfaces for session beans. The required business interface for a session bean can be a plain Java interface rather than an EJBObject, EJBLocalObject, or java.rmi.Remote interface.
2. Elimination of the requirement for home interfaces for session beans.
3. Encapsulation of environmental dependencies and JNDI access through the use of annotations, dependency injection mechanisms, and simple lookup mechanisms.
4. Introduction of Java metadata annotations to be used as an alternative to deployment descriptors.
