No, though one does get included in the Seam-PDF example. You can safely drop most of MC/JPA/Hibernate stuff in such setup - though Seam does have some dependencies I couldn't get rid from: namely ejb3-persistence.jar (doh!) and hibernate-validator.jar (expressions, facesMessages and validators Seam components)

there are alternatives to using MC - see http://www.jboss.com/index.html?module=bb&op=viewtopic&t=104525 - though Pete is right, MC is the easiest to set up

>From top of my head (incomplete list):
Stateful, Stateless and message-driven EJBs (forget about @Stateful and @Stateless). Entity beans are in, though.
Persistence Context injection via @PersistenceContext (use @In)
You have to (or, rather, you better to) use Seam-managed transactions and Seam-managed persistence contexts if you're outside J2EE container

HTH,
