@MappedSuperclass
public abstract class BasicJpaEntity<E extends IdentifiableEntity,I extends EntityIdentifier>
extends AbstractJpaEntity<E,I>

This abstract class must be extended by all basic JPA entities that don't fit to the persistence rules of the Silverpeas Persistence API. Usually it means to be used for the migration of entities from the old persistence way (J2EE BMP) to JPA. Please be careful into the child entity classes about the use of @PrePersist and @PreUpdate annotations. In most of cases you don't need to use them, but to override performBeforePersist() or performBeforeUpdate() methods without forgetting to invoke the super call.
