[jboss-user] [JBoss Seam] - Pure JPA Persistense Layer

I'm starting the development of an application that at this point will have a single web interface but later it will be necessary to build another interfaces as well, for example a Swing front end.

So I would like to have a pure JPA layer that doesn't import anything but javax.persistence.* classes and annotations allowing me to use it outside a jee 5 container but I also would like to use Seam and Hibernate validation in my Web Interface as I am using in other projects. Is there any way to achieve that?

I thought about extending my pure JPA classes and then add the complementary annotations (such as @Name and @Length), but that would cause a ClassCastException later, right? My EntityManager won't persist my new classes.

What you guys recommend me?

Thank you in advance,
Augusto Fontes
