我在netbeans中创建了一个java web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，这项工作很成功。

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，我注意到有些类抛出异常，我注意到带有vars的实体类List抛出例外，好像它们无法序列化。

我想带给我一个实体列表是一个请求。

我在同一个项目中有一个实体bean，它在Web应用程序中有我的会话bean ......

我曾与Glass Fish 3.1.2合作 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;................

主要类别是：

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;
}

}

1 个答案:

答案 0 :(得分：2)

我的回答可能不合适，但我遇到了这个问题并解决了。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。

至于理解为什么这个是我们得到的神秘错误信息，以下说明可能有所帮助：

  • 首先，实体bean（现在已被使用Java Persistence API取代）是一种EJB，因此可以在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，即公共对象请求代理体系结构
    • 来实现
  • CORBA是围绕您可以远程实例化和操作对象的想法而构建的。例如，您可以从主容器 outside EJB容器中创建EJB实例，设置其成员属性，运行其方法。 CORBA是一个通用标准，理论上任何“客户端”都可以使用（例如，一个符合CORBA的调用的C ++程序在理论上可以在这里工作。但是当然，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，但我认为你的主程序成功连接到EJB容器，EJB容器抛出异常，然后返回一些CORBA没想到，这损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就是调试程序并找到抛出异常的EJB的位置，然后看看直接在调试器中的异常。

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。

希望这有帮助， 约什
