I'm using EXTENDED Persistence Context with a SFSB, expecting that "the
lifecycle of the persistence context is binded to the lifecycle of the Stateful
Session Bean" but this dont work.
I'm get org.hibernate.LazyInitializationException in the second lap, this is
the same method invocation with different results. May by a Bug?
This is my code:
CLIENT
public class Client
{
public static void main(String[] args) throws Exception
{
InitialContext ctx = new InitialContext();
IProceso proceso = (IProceso) ctx.lookup("cine/ProcesoBean/remote");
List peliculas = null;
// lap 1
proceso.crearDatos();
peliculas = proceso.listarPeliculas();
showPeliculas(peliculas);
proceso.grabar();
System.out.println("Lap 1 OK!");
// lap 2
proceso = (IProceso) ctx.lookup("cine/ProcesoBean/remote");
peliculas = proceso.listarPeliculas();
showPeliculas(peliculas);
proceso.grabar();
System.out.println("Lap 2 OK!");
}
SERVER
@Stateful
public class ProcesoBean implements IProceso{
@PersistenceContext(type=PersistenceContextType.EXTENDED)
private EntityManager em;
public void crearDatos(){
System.out.println("crearDatos");
System.out.println("EM: " + em.hashCode());
// make data insert on DB
....
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public List listarPeliculas() {
List pelis = null;
pelis = em.createQuery("from Movie p where p.salaCompleta is
false").getResultList();
return pelis;
}
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public void salaCompleta(Long idpelicula) {
Movie pelicula = em.find(Movie.class, idpelicula);
pelicula.setSalaCompleta(Boolean.TRUE);
}
@Remove
public void grabar() {
}
