Migration from Preview 5 to EJB 3.0 Beta

This document discusses how you can upgrade your Preview 5 applications of EJB

3.0 with EJB 3.0 Beta.  It kinda also is a diff between the EDR2 and Public

Draft of the specification.

persistence.xml and .par packages

There is no more hibernate.properties or hibernate.cfg.xml.  A spec mandated

XML file is now the way to configure everything.  Please read the packaging

tutorial and entitymanager tutorial.

No more @Inject

@Inject has been removed from the specification.  To inject EntityManager, use

the new @PersistenceContext annotation or the @PersistenceUnit annotation if

you are injecting EntityManagerFactory.

@AssociationTable -> @JoinTable

@AssociationTable has been renamed to @JoinTable

Security Annotations

@MethodPermissions has been renamed to @javax.annotation.security.RolesAllowed

@Unchecked to @javax.annotation.security.PermitAll

@Exclude to @javax.annotation.security.DenyAll

@RunAs has also been moved to the javax.annotation.security package
