Question

我遇到了EJB / Glassfish的问题。我正在开发一个客户端 - 服务器应用程序，其中客户端创建一个实体对象，并且必须将其发送到服务器应用程序，该应用程序必须将该实体持久保存在其数据库中。我选择使用会话bean与服务器通信。我已经实现了一些简单的情况，其中会话bean中的方法将字符串或int作为输入，它工作正常。当我尝试将实体对象作为输入时出现问题。

我报告我的实体类：

@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;
}

这是我的会话bean：

 @Stateless
 public class GestoreLibreriaRemoto implements GestoreLibreriaRemotoRemote {

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

这是我的客户端应用程序：

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);
    }
}

在我的主要课程中，我只是调用GestoreLibreriaLocale.prova（），我收到以下错误：

错误日志继续，我不报告整个日志，但如果你需要它，我可以发布它。请帮助我，我正在努力解决这个问题。谢谢你的关注，弗朗西斯

这似乎是当前Java版本中的一个错误（例如1.7.0_55和1.8.0_05），请看一下这个问题：GLASSFISH-21047

要使其正常运行，请安装较旧或较新的Java版本（例如1.7.0_051或1.8.0_020）。
