This scenario does not work on GlassFish v3.0.1 promoted build:
@SessionScoped
@Stateful
public class EntityManagerProducer {
@PersistenceContext(type=PersistenceContextType.EXTENDED)
private EntityManager em;
@Produces
public EntityManager getEntityManager() {
return em;
}
}
@Named
@SessionScoped
@Stateful
public class A {
@Inject
private EntityManager em;
public List<University> getUniversities() {
return em.createNamedQuery("University.findAll").getResultList();
}
}
<h:dataTable value="#{a.universities}" var="item">
<h:column>
<h:outputText value="#{item.name}"/>
</h:column>
</h:dataTable>
Exception:
Caused by: java.lang.NullPointerException
at com.sun.enterprise.container.common.impl.EntityManagerWrapper.createNamedQuery(EntityManagerWrapper.java:522)
at lt.mycompany.template.A.getUniversities(A.java:42)
Additionally, checking em.getDelegate() reveals it is null.
If I change PersistenceContext type to TRANSACTIONAL, the case starts working.
Also, if some operations on entity manager are done before injecting it to A, everything starts to work too.
It seems like EntityManager delegate is not initialized if it is of type EXTENDED.
