    lazy initialization and @PersistenceContext(EXTENDED)

    kk null Newbie

      I have a couple of annotated classes deployed, a stateful bean and a client (web), running on jboss-4.0.3SP1

      stateful bean declaration as follows:

      @Stateful
      
      public class TestBeanImpl implements TestBean {
      
       @PersistenceContext(type = PersistenceContextType.EXTENDED)
       EntityManager em;
      
      ...
       public X businessMethod() {
      
       return em.createQuery("").getSingleResult();
       }
      }
      


      Entity X contains a collection, that fails to lazily initialize in this test:

       InitialContext ctx = new InitialContext();
       TestBean testBean = (TestBean)ctx.lookup(TestBean.class.getName());
      
      
       X x = testBean.businessMethod();
       List l = x.getList();
       Y y = (Y)l.get(0);
      


      The last line throws an exception: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role:

      What am I doing wrong?
