Hi, to all
i have this scenario

1)I have my entity with many collection (Lazy association)

2)This is my mdb

 public class LoginRequest implements MessageListener {

 public LoginRequest() {
 }

 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());


 if(_cli!=null)
 Send(_cli);

 } catch (Exception e) {
 System.err.println("Exception in SimpleMessageBean");
 e.printStackTrace();
 }
 }


 public void Send(Clienti vo){
 try {
 System.out.println("-->>");
 TopicConnectionFactory connectionFactory;
 Topic queue;
 TopicSession session;


 Hashtable environment = new Hashtable();
 environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
 environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
 environment.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099"); // remote machine IP
 InitialContext ctx = new InitialContext(environment);
 Object obj = ctx.lookup("topic/VdeResponseLoginQueue"); //ejb-name
 System.out.println("-->> lookup object successfully");
 queue = (Topic) obj;
 connectionFactory=(TopicConnectionFactory) ctx.lookup("/TopicConnectionFactory");
 TopicConnection connection = connectionFactory.createTopicConnection();
 session =
 connection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);

 connection.start();
 ObjectMessage message = session.createObjectMessage();
 System.out.println("Ho ricevuto l'ordine da te ora "+vo.getNome());
 message.setObject(vo);
 message.setJMSCorrelationID(vo.getNome());
 System.out.println("Preparato message per "+vo.getCognome()+" "+vo.getNome());
 MessageProducer messageProducer = session.createProducer(queue);

 messageProducer.send(message);

 session.close();
 connection.close();
 connection=null;

 } catch (Exception e) {
 System.out.println("Errroe in sendMessage "+e.getMessage());
 e.printStackTrace();
 }
 }



 }


this is my Session Facade

@Stateless
//@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public class ClientiFacade implements ClientiFacadeLocal,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 id=(Clienti) em.createNamedQuery("Clienti.findByNome").setParameter("nome",nome).getSingleResult();
 return em.getReference(Clienti.class, id.getIdcliente());
 }





}

my client

 public class TestTopic {



 public TestTopic() {

 }



 public void Send(String cosa){
 try {
 System.out.println("-->>");
 TopicConnectionFactory connectionFactory;
 Topic queue;
 TopicSession session;


 Hashtable environment = new Hashtable();
 environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
 environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
 environment.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099"); // remote machine IP
 InitialContext ctx = new InitialContext(environment);
 Object obj = ctx.lookup("topic/VdeResponseLoginQueue"); //ejb-name
 System.out.println("-->> lookup object successfully");
 queue = (Topic) obj;
 connectionFactory=(TopicConnectionFactory) ctx.lookup("/TopicConnectionFactory");
 TopicConnection connection = connectionFactory.createTopicConnection();
 session =
 connection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);

 connection.start();
 ObjectMessage message = session.createObjectMessage();
 ClientiFacadeRemote facade=(ClientiFacadeRemote)CachingServiceLocator.getInstance().getRemoteHome(ClientiFacade.class);
 Clienti vo=facade.findByName(cosa);



 System.out.println("Ho ricevuto l'ordine da te ora "+vo.getNome());
 System.out.println("Tarifa "+vo.getIdtariffa().getIdtariffa());
 System.out.println("Lingue "+vo.getLingua().getStringa());

 System.out.println("DVD Collection 9 "+vo.getLingua().getDvdCollection9().size());


 message.setJMSCorrelationID(vo.getNome());
 message.setObject(vo);
 System.out.println("Preparato message per "+message.getJMSCorrelationID()+" "+vo.getCognome());
 MessageProducer messageProducer = session.createProducer(queue);

 messageProducer.send(message);

 session.close();
 connection.close();
 connection=null;

 } catch (Exception e) {
 System.out.println("Errroe in sendMessage "+e.getMessage());
 e.printStackTrace();
 }
 }

 public static void main(String args[]){
 TestTopic t = new TestTopic();
 t.Send("devis");
 }


}

When my client call
vo.getLingua().getDvdCollection9().size()

throw this error
Errroe in sendMessage failed to lazily initialize a collection of role: vde.com.ejb.vo.Lingue.dvdCollection9, no session or session was closed
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: vde.com.ejb.vo.Lingue.dvdCollection9, no session or session was closed

I have read about "Open Session in View" and AOP solution ... but i'dont use web app i have some Flex/Apollo (Adobe) application.
I have used also, PersistenceContext Extended, Transaction NOT_SUPPORTED etc.
Can you help me how i can design this scenario? i'm disperate... how i can use my Lazy Collection....?
Thanks in advance
