Hi Henrique,
i'm not using in my application DataService but only jms/queue, then i
haven't configure
data-management. (JBoss/Hibernate EntityManager)
This my scenario:
Java side
1)My Entity Class
@Entity
@Table(name = "clienti")
....
@Column(name = "nome", nullable = false)
private String nome;
@Column(name = "cognome", nullable = false)
private String cognome;
@Column(name = "indirizzo")
private String indirizzo;
@JoinColumn(name = "lingua", referencedColumnName = "idlingua")
@ManyToOne()
private Lingue lingua;
.....
My Lingue class Entity
@Id
@Column(name = "idlingua", nullable = false)
private Integer idlingua;
@Column(name = "stringa", nullable = false)
private String stringa;
@Column(name = "immagine")
private Integer immagine;
@OneToMany(mappedBy = "lingua")
private Collection<Users> usersCollection;
@OneToMany(mappedBy = "langsubtitles")
private Collection<Vhs> vhsCollection;
My Session Facade
//@Statless
@Stateful
public class ClientiFacade implements ClientiFacadeLocal {
@PersistenceContext(type=PersistenceContextType.EXTENDED)
private EntityManager em;
/** Creates a new instance of ClientiFacade */
public ClientiFacade() {
}
public void create(Clienti clienti) {
em.persist(clienti);
}
public void edit(Clienti clienti) {
em.merge(clienti);
}
public void destroy(Clienti clienti) {
em.merge(clienti);
em.remove(clienti);
}
public Clienti find(Object pk) {
return (Clienti) em.find(Clienti.class, pk);
}
public List findAll() {
List lista = null;
try {
UserTransaction tx = (UserTransaction) new
InitialContext().lookup("UserTransaction");
tx.begin();
lista=em.createQuery("select object(o) from Clienti as
o").getResultList();
tx.commit();
} catch (Exception ex) {
ex.printStackTrace();
}
finally {
em.clear();
}
return lista;
}
public Clienti findByName(String nome) {
Clienti _cli
=(Clienti)em.createNamedQuery("Clienti.findByNome").setParameter("nome",nome).getSingleResult();
return _cli;
}
}
My Java Mdb
public void onMessage(Message message) {
try {
Clienti _msg = (Clienti)
((ObjectMessage)message).getObject();
System.out.println("MessageBean onMessage"
+_msg.getNome());
ClientiFacadeLocal
facade=(ClientiFacadeLocal)CachingServiceLocator.getInstance().getLocalHome(ClientiFacade.class);
Clienti _cli=facade.findByName(_msg.getNome());
System.out.println("onMessage toString
"+_cli.toString());
.....
push into a queue my _cli object ..... my
vde_response_login quee

Thanks have you some idea? but in this scenario i think i don't
configure data-management right?
