Hibernate Annotation
Hibernate 3.1 offers a variety of additional annotations that you can mix/match with your EJB 3 entities. They have been designed as a natural extension of EJB3 annotations. To empower the EJB3 capabilities, hibernate provides specific annotations that match hibernate features. The org.hibernate.annotations package contains all these annotations extensions.
