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，服务器应用程序必须将该实体保留在其数据库中。我选择使用会话 bean 与服务器进行通信。
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整数作为输入，并且工作正常。当我尝试提供实体对象作为输入时，问题就出现了。
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);
}
}
在我的主类中，我只需调用 GestoreLibreriaLocale.prova() 即可得到以下错误：

错误日志继续，我不报告整个日志，但如果您需要它，我可以发布它。
请帮助我，我已经研究了几天但没有解决它。
感谢您的关注，
