What's the advantage of the Bean interface model of
3.0 over the pervious home/component interface model in EJB 2.x?

Some of the advantages:
- Ease of development in EJB3, since there is no longer the need for having Home interfaces.
- The required business interface for a session bean can be a plain
interface rather than an EJBObject, EJBLocalObject, or java.rmi.Remote interface.
- Also, with the advent of annotations, there is no longer a need for deployment descriptors.

- POJO and POJI
- Configuration by exception
