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

然后我生成了会话 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，并且我注意到带有 vars List 的实体类抛出好像它们无法序列化的异常。

我想给我带来实体列表是一个请求。

我在同一个项目中拥有实体 bean，该项目具有我的会话 bean，在 Web 应用程序中......

我使用 Glass Fish 3.1.2
Netbeans 7.1.2
EclipseLink 2.0

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;................

主类是：

public class Main {

public static void main(String[] args) {

    long id = 2;


    bank.setId(id);
    UserApplication userApplication = GetBean.getUserFacade().find(id);
    System.out.println("user: " + userApplication.getFirstName());


    }

}

GetBean 是实用程序类，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;
}

}

我的回答可能不正确，但我遇到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 中对此进行了测试，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。

就理解为什么这是我们得到的神秘错误消息而言，以下解释可能会有所帮助：

  • 首先，实体 bean（现在被使用 Java Persistence API 取代）是一种 EJB，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”一个 EJB。它通过使用 CORBA（通用对象请求代理体系结构）来做到这一点
  • CORBA 是围绕您可以远程实例化和操作对象的想法构建的。例如，您可以创建 EJB 实例、设置其成员属性、运行其方法，所有这些都来自EJB 容器外部的 main 方法。CORBA 是理论上任何“客户端”都可以使用的通用标准（例如，进行符合 CORBA 的调用的 C++ 程序理论上可以在这里工作。但当然，Java 世界中的大多数人只是使用 CORBA 来访问EJB 容器。
  • 你得到的特定错误是ORBIO00013: Stream corrupted，我不完全理解，但我认为它的意思是你的主程序成功连接到 EJB 容器，EJB 容器抛出异常，然后返回了 CORBA 没有预料到的东西，这损坏了用于发送响应的流。
  • 真正的问题是 CORBA 没有很好地处理 EJB 中抛出的异常，因此解决此问题的唯一方法是调试程序并找到 EJB 中抛出异常的位置，然后查看异常直接在调试器中。

完成所有这些最终帮助我理解了一个简单的数据库连接问题（！）是问题所在。

希望这会有所帮助，乔希
