Serialization EJB。当我使用var List调用会话Bean时抛出：this javax.ejb.EJBException:java.rmi.marshallexception

我在netbeans中创建了一个javaweb项目，我创建了我的实体bean，后来部署了我的项目来生成我的数据库，这项工作是成功的

然后我生成会话bean来访问创建的数据库。我创建了一个主类来测试会话bean，当我测试通过会话bean接口调用的方法“find”时，我注意到一些类抛出异常，我注意到带有vars List的entities类抛出异常，就好像它们无法序列化一样

我想给我带来的实体列表是一个请求

我在同一个项目中有实体bean，在web应用程序中有我的会话bean

我与玻璃鱼3.1.2一起工作
Netbeans 7.1.2

实体持久性是：

@Entity

public class UserApplication implements Serializable {

private static long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long idUserApplication;
@Basic(optional=false)
@Column(nullable=false)
private String dcn;
@Basic(optional=false)
@Column(nullable=false)
private String password;
@Basic(optional=false)
@Column(nullable=false)
private String title ;
@Basic(optional=false)
@Column(nullable=false)
private String firstName;
@Basic(optional=false)
@Column(nullable=false)
private String lastName;
@Basic(optional=false)
@Column(nullable=false)
private String ci;
@Basic(optional=false)
@Column(nullable=false)
private String personalEmail;
@Basic(optional=false)
@Column(nullable=false)
private String workEmail;

@OneToMany
@JoinColumn(name = "userApplication_id", nullable = false)
private List<Account> accounts;
@OneToMany
@JoinColumn(name = "userApplication_id", nullable = true)
private List<CreditCard> creditCards = null;

@ManyToMany
@JoinTable(name="UserApplication_BeneficiaryThird", joinColumns=@JoinColumn
        (name="userApplication_id", nullable = false), inverseJoinColumns=
        @JoinColumn(name="beneficiaryThird_id", nullable = false))
private List<BeneficiaryThird> beneficiariesThird = null;

@OneToMany
@JoinColumn(name = "userApplication_id_beneficiary", nullable = true)
private List<BeneficiaryBankItself> beneficiariesBankItself = null;

@ManyToMany
@JoinTable(name="UserApplication_TransactionRule", joinColumns=@JoinColumn
        (name="userApplication_id", nullable = false), inverseJoinColumns=
        @JoinColumn(name="transactionRule_id", nullable = false))
private List<TransactionRule> transactionRules = null;

@OneToOne(mappedBy = "userApplication", optional = true, cascade = CascadeType.ALL)
private SessionCookie cookieId = null;................

GetBean是实用程序类，它是：

public class GetBean {



public static BankFacadeLocal getBankFacade() {

    BankFacadeLocal bankFacade = null;
    String jndiName = beans.BankFacadeLocal.class.getName();
    try {
         //bankFacade = (BankFacadeLocal) new InitialContext().lookup("java:global/IntegrationBanking/BankFacade!sessionBeans.BankFacadeLocal");
          bankFacade = (BankFacadeLocal) new InitialContext().lookup(jndiName);        
    } catch (NamingException ex) {
        Logger.getLogger(GetBean.class.getName()).log(Level.SEVERE, null, ex);
    }

    return bankFacade;
 }

 public static UserApplicationFacadeLocal getUserFacade() {

    UserApplicationFacadeLocal userFacade = null;
    String jndiName = UserApplicationFacadeLocal.class.getName();
    try {
         // userFacade = (UserApplicationFacadeLocal) new InitialContext().lookup("java:global/IntegrationBanking/UserApplicationFacade!beans.UserApplicationFacadeLocal");
         userFacade = (UserApplicationFacadeLocal) new InitialContext().lookup(jndiName);        
    } catch (NamingException ex) {
        Logger.getLogger(GetBean.class.getName()).log(Level.SEVERE, null, ex);
    }

    return userFacade;
} 

}

我的回答可能有误，但我经历了这个问题并解决了它。对我来说，问题只是我的数据库没有连接！我在Glassfish中测试了这个问题，确认了数据库连接问题并修复了它，然后这个错误就消失了

就理解这是我们得到的神秘错误消息的原因而言，以下解释可能会有所帮助：

• 首先，实体bean（现在被Java持久性API取代）是一种EJB类型，因此在EJB容器中运行
• 您的主类存在于EJB容器之外，因此必须“调用”EJB。它通过使用CORBA（公共对象请求代理体系结构）来实现这一点
• CORBA是基于您可以远程实例化和操作对象的思想构建的。例如，您可以创建一个EJB实例，设置它的成员属性，运行它的方法，所有这些都可以从EJB容器之外的主方法开始。CORBA是一个在理论上任何“客户端”都可以使用的通用标准（例如，一个允许CORBA兼容调用的C++程序在理论上可以工作。但是，当然，java世界中的大多数人都只是使用CORBA来访问EJB容器。
• 您得到的特定错误是

  ORBIO00013:Stream corrupted

  ，我不完全理解，但我认为这意味着您的主程序成功地连接到EJB容器，EJB容器抛出了一个异常，然后返回了CORBA没有预料到的内容，这破坏了用于发送响应的流
• 真正的问题是CORBA在处理EJB中抛出的异常方面做得不是很好，所以解决这个问题的唯一方法是调试程序，找到EJB中抛出异常的位置，然后直接在调试器中查看异常

所有这些最终帮助我理解了一个简单的数据库连接问题（！）就是问题所在

希望这有帮助， Josh

我在这个链接中找到了更明确的解释问题的方法，但还没有找到解决方案
