Hi to all,
i'm disperate with my prblem.
I have this scenario:
1)I'm using jms/mdb ejb3 with jboss 4.2
2)I'm using FDS with Consumer/Producer comp.
My mdb
public void onMessage(Message message) {
try {
Clienti _msg = (Clienti)
((ObjectMessage)message).getObject();
System.out.println("MessageBean onMessage"
+_msg.getNome());
ClientiFacadeRemote
facade=(ClientiFacadeRemote)CachingServiceLocator.getInstance().getRemoteHome(ClientiFacade.class);
Clienti _cli=facade.findByName(_msg.getNome());
System.out.println("onMessage toString "+_cli.toString());
Clienti _cl = new Clienti(_cli);
//to queue
Send(_cl);
this my ClientFacade
@Stateless
//@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public class ClientiFacade implements ClientiFacadeRemote {
@PersistenceContext()
private EntityManager em;
//private EntityManagerFactory entityManagerFactory =
Persistence.createEntityManagerFactory("NuovVdeUN");
//EntityManager em = entityManagerFactory.createEntityManager();
/** 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() {
return em.createQuery("select object(o) from Clienti as
o").getResultList();
}
public Clienti findByName(String nome) {
Clienti _cli
=(Clienti)em.createNamedQuery("Clienti.findByNome").setParameter("nome",nome).getSingleResult();
em.clear();
return _cli;
}
}
vde.com.ejb.vo.Clienti is my EJB3 Entity with some Lazy collection
ActionScript DTO
import mx.collections.ArrayCollection;
[Managed]
[RemoteClass (alias="vde.com.ejb.vo.Clienti")]
public class Clienti
......
I have made 30 test/example with Persistence.Extended @Steful etc.
my last test using EntityManager.clear for detached entity...
but my ActionScript dto always try to initialize all my collection
lazy and throws my exception "Lazy and
flex.messaging.io.ArrayCollection.<init>(ArrayCollection.java:44
........
Why if my backend doesn't initiliaze some Lazy Collection why my Flex
wonts that all lazy collection are initilaze? Pls it's a week that i
have this problem.
I have read in www.graniteds.org (oper source alternative) .."With
GDS, you can keep those uninitialized references with lazy"... but how
i can doing this with Fds.
I have also download Live Cycle data beta but i have the same problem.
Can you help me pls?
