EJB应用程序中的CORBA异常

Question

I've got a problem with EJB/Glassfish. I'm working on a client-server application in which the client creates an entity object and must send it to the server application, which must persist the entity in its database. I've choose to use session beans to communicate with the server. I've implemented some simple cases in which a method in the session bean takes as input a string or an int and it works fine. The problem arises when I try to give an entity object as input.

I report my entity class:

@Entity
public class Example implements Serializable {
private static final long serialVersionUID = 1L;
@Id
String nome;

public void setNome(String nome) {
    this.nome = nome;
}

public String getNome() {
    return nome;
}

Here my session bean:

 @Stateless
 public class GestoreLibreriaRemoto implements GestoreLibreriaRemotoRemote {

 @Override
 public String getProva(Example prova) {
    return prova.getNome();
 }

Here my client application:

public class GestoreLibreriaLocale {

public static void assegnaCategoriaACopia(CopiaUtente copia, Categoria categoria) throws 

public void prova() {
   GestoreLibreriaRemotoRemote gestore = lookupGestoreLibreriaRemotoRemote();
   Example example = new Example();
   prova.setNome("hodor");
   System.out.println(gestore.getProva(example));
}

private  GestoreLibreriaRemotoRemote lookupGestoreLibreriaRemotoRemote() {
    try {
        Context c = new InitialContext();
        return (GestoreLibreriaRemotoRemote) c.lookup("java:global/ServerMDB/ServerMDB-ejb/GestoreLibreriaRemoto");
    } catch (NamingException ne) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", ne);
        throw new RuntimeException(ne);
    }
}

In my main class I simply call GestoreLibreriaLocale.prova() and i get the following error:

The error log continues, I don't report the whole log but if you need it I can post it. Please help me, I'm working on it from days without resolving it. Thanks for the attention, Francesco

This seems to be a bug in the current Java versions (eg 1.7.0_55 and 1.8.0_05 ), have a look at this issue: GLASSFISH-21047

To make it work, install either an older or a newer Java version (eg 1.7.0_051 or 1.8.0_020 ).
