    JPA UserTransaction rollback does not work

      I try to describe my environment shortly. Technologies: EJB 3.1, JSF, JBoss 7.1.1

      There are Servise-classes (@SessionScoped @Stateful). Servise-classes call Dao classes (@Stateless)

      I want :
      use EntityManager only into @StateLess beans (Dao)
      have short transaction in most cases (like persist, merge)
      have one long transaction for some multistep-methods (methods are in Dao also)
      have actual (up to date, without first-level cache) data

      I have: Pesistense.xml
      <property name="hibernate.hbm2ddl.auto" value="create-drop"/>


      public class UserDaoBean implements UserDAO, Serializable {

      @PersistenceContext(name = "MyEntityManager")
      private EntityManager em;

      public void update(User user) throws Exception {
      User tmpUser = getUser(user.getUser());
      //some code, should be rollback, if it is an exception

      Transaction interceptor
      public class TransactionInterceptor implements Serializable {

      private UserTransaction userTransaction;

      public Object verifyAccess(InvocationContext context) throws
      Exception {
      Object result = null;

      try {
      result = context.proceed();
      } catch (Exception e) {
      throw new CustomRuntimeException(e.getMessage());
      return result;

      Problem: If it is throw an Exception into Dao method, part data will save in DB instead of total rollback.

      I think, is need Join Transaction to EM. Or disconnect persists each item to the DB right away (using cache). I've try different ways, but didn't have success.

      Thanks for in advance!
