Faces: troubles in setting up Seam-managed transactions

[juergen.zimmermann]

I'm using JBoss 7 Jenkins build 1605. My EAR has an EJB module and 2 web modules (one for REST, one for Weld/Mojarra/Seam). The following config class in the 2nd web module causes the stacktrace below. Any hint is appreciated.

public class SeamConfig {
        @Produces
        @ConversationScoped
        @PersistenceContext
        @SuppressWarnings("unused")
        private EntityManager em;
}

Stacktrace:

According to the document of the Seam Persistence....
U can try to use Seam managed persistence in the case.

public class EMFProducer {
        @Produces
        @ConversationScoped
        @PersistenceUnit
        @ExtensionManaged
        private EntityManagerFactory emf;
}

And use

@Inject EntityManager em;

directly in ur code.

Hantsy is correct, you're missing the @ExtensionManaged annotation which will tell CDI not to create it as a normal producer, but let an extension (in this case Seam Persistence) figure it out.
