EntityManager OR Hibernate Session

[tathagat]

Hi all.
When using Seam and JPA with tomcat without Jboss embedded, I got 2 options.

1) Use EntityManager

@In javax.persistence.EntityManager em;

2) Use Hibernate Session

@In private org.hibernate.Session session

My question is, is there any advantage of using one over the other? If yes, what?

Thanks in advance!

EntityManager is standards compliant, so theoretically you can change to any other JPA implementation.

Session provides more features but is non portable.

Thanks!

I also realized that it is easier to use Hibernate Session as I do not need to set JNDI. Neither do I need to put some extra libs in Tomcat6/lib folder.

Makes it very portable to use in another web server, for example Jetty.

Cheers
