面试题 - 代码与编程题 - EJB的基本架构

一个EJB包括三个部分:
Remote Interface 接口的代码

import javax.ejb.EJBObject;
import java.rmi.RemoteException;

public interface Add extends EJBObject {
  // some method declare
}

Home Interface 接口的代码

import java.rmi.RemoteException;
import jaax.ejb.CreateException;
import javax.ejb.EJBHome;

public interface AddHome extends EJBHome {
  // some method declare
}

EJB类的代码

  import java.rmi.RemoteException;
  import javax.ejb.SessionBean;
  import javx.ejb.SessionContext;
  public class AddBean Implements SessionBean
  {
    // some method declare
  }
