    Could not find EntityManagerFactory

    Moritz Winter Newbie
      Hi,

      id like to mention that i searched for this issue and read alot of documentation but i couldn't find a solution.

      I have a project (EJB 3.0, packaged as EAR) with a view (JSF 2.0) and persistence (JPA 2.0, Hibernate) layer. To avoid the lazy initialization support and other issues I tried to introduce a Seam Managed Persistence Context with Seam 3.0.0.Final.
      For this i wrote the following producer class:

      import javax.enterprise.context.ConversationScoped;
      import javax.enterprise.inject.Produces;
      import javax.persistence.EntityManagerFactory;
      import javax.persistence.PersistenceUnit;

      import org.jboss.seam.solder.core.ExtensionManaged;

      class PersistenceProvider {
           
           @SuppressWarnings("unused")
           @ExtensionManaged
           @Produces
           @PersistenceUnit
           @ConversationScoped
           private EntityManagerFactory producerField;
      }

      And changed the @PersistenceContext Annotation on my EntityManager fields to @Inject.

      If Iam trying to use the EntityManager now I'm getting the following stacktrace:

      WARNUNG: StandardWrapperValve[Faces Servlet]: PWC1406: Servlet.service() for servlet Faces Servlet threw exception

      Debugging the applicaton on Glassfish 3.1 provided me with the following insights

      The entity manager is a proxy of the type "entityManager SMPC-org$jboss$seam$persistence$ManagedPersistenceContextExtension-com$example$PersistenceProvider$producerField[@javax$enterprise$context$ConversationScoped()@javax$enterprise$inject$Produces()@javax$persistence$PersistenceUnit(name=,unitName=)@org$jboss$seam$solder$core$ExtensionManaged()]_$$_WeldClientProxy"

      The producer field can't be found in the beans-Field of the BeanManager in the scope of the method org.jboss.seam.persistence.ManagedPersistenceContextBeanLifecycle.getEntityManagerFactory but in a BeanManager injected into my DAOs.

      I tried some variations like qualifiying the producer field, trying to inject a entity manager in the view layer services and adding the unitName and/or name of my persistence unit to the @PersistenceUnit Annotation of the producer field.

      Any suggestions what Im doing wrong here?
