EJB Not Retrieving database updates

Question

Hello,
I have named queries in EJBs built of tables. For example:
@Entity
@NamedQueries({
@NamedQuery(name = "DadUser.findAll", query = "select o from DadUser o"),
@NamedQuery(name = "DadUser.findOne", query = "select o from DadUser o " +
                                              "where o.userId = :user_id")
@Table(name = "DAD_USER")
public class DadUser implements Serializable {
    @Column(name="ACTIVE_FLAG")
    private String activeFlag;
    @Column(name="FULL_NAME")
    private String fullName;
    private String secure;
    @Id
    @Column(name="USER_ID", nullable = false)
    private String userId;
    public DadUser() {
    getters and setters .....
        return activeFlag;
    My Session Facade:
@Stateless(name="dadFacade")
public class dadFacadeBean implements dadFacadeRemote, dadFacadeLocal {
    @PersistenceContext(unitName="Model")
    private EntityManager em;
    public dadFacadeBean() {
    public Object mergeEntity(Object entity) {
        return em.merge(entity);
    public Object persistEntity(Object entity) {
        em.persist(entity);
        return entity;
    /** <code>select o from DadUser o where o.userId = :user_id</code> */
    public DadUser queryDadUserFindOne(Object user_id) {
        return (DadUser) em.createNamedQuery("DadUser.findOne").setParameter("user_id", user_id).getSingleResult();
    }Backing bean:
@EJB
    private dadFacadeLocal df;
    public List<DadRequests> getUsers() {
        return df.queryDadUserFindOne('test');
    }If I make a change to a field on another form the changed data displays in the list. However, if I make a change directly in the Oracle database and commit the changed value, the data does not change in the JSF app unless I re-deploy it. I close the app and re-open and clear IE and the old value still displays. I have tried em.flush but nothing seems to refresh the list when Oracle is changed directly. Please HELP ! Thank you.

Just a shot:
I don't know if You typed it right but you try to call:
public DadUser queryDadUserFindOne(Object user_id) {
        return (DadUser) em.createNamedQuery("DadUser.findOne").setParameter("user_id", user_id).getSingleResult();
    }which returns DadUser, and then put it into List of DadRequests
public List<DadRequests> getUsers() {
        return df.queryDadUserFindOne('test');
    }I don't see how can it work ;), but You asked about EJB,
The reason why EJB returns old (not updated) values is that entity bean is held on app server and cached there, if you would have changed data in DB via EJB module it would also update cache in entity beans container.
So I think that it has nothing to do with JSF :].
