Hibernate EntityManager is an implementation of the Java Persistence API. Also it is much closer to the standards since it is compatible with EJB 3.0 specification.

At a much lower level, it means you dont need to use your hbm.xml files for OR mapping or define your entity classes in persistence.xml.

So close to the standard that we pass the TCK ;)
