Hello,
I use EJB 3.0 and JBoss AS 4.2.3.
I am using a SFSB that uses JPA to persist its data. The dependency injected EntityManager
has a PersistenceContextType extended.
Here is excerpt from my bean.
| @Stateful
| @ApplicationException(rollback = false)
| @TransactionManagement(TransactionManagementType.BEAN)
|
| public class ModelFacade implements IModelFacadeRemote {
|
| private static final long serialVersionUID = 1L;
|
| @Resource
| private UserTransaction utx;
|
| @PersistenceContext(unitName = "foo", type =
PersistenceContextType.EXTENDED)
| protected EntityManager em;
|
| @SuppressWarnings("unchecked")
| public Collection<Object> findAllFreshItems(Class type) {
|
| String sql = "SELECT i FROM " + type.getSimpleName() + " i";
| List<Object> resultList = em.createQuery(sql).setHint(
| QueryHints.REFRESH, HintValues.TRUE).getResultList();
| return resultList;
| }
|
| @SuppressWarnings("unchecked")
| public Collection<Object> findAllItems(Class type) {
|
| String sql = "SELECT i FROM " + type.getSimpleName() + " i";
| List<Object> resultList = em.createQuery(sql).getResultList();
| return resultList;
| }
|
| // findSingleItem
| @SuppressWarnings("unchecked")
| public Object findSingleItem(Object id, Class type) {
| return em.find(type, id);
| }
|
The bean and the application works fine, but if JBoss AS tries to passivate I get the
errors:

It seems as if JBoss AS is not be able to passivate the bean.
For all the tips I would be very grateful!
Best regards,
Dmitri
