EJB的基本架构

一个EJB包括三个部分:
Remote Interface 接口的代码
package Beans;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface Add extends EJBObject
{
//some method declare
}
Home Interface 接口的代码
package Beans;
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
package Beans;
import java.rmi.RemoteException;
import javax.ejb.SessionBean;
import javx.ejb.SessionContext;
public class AddBean Implements SessionBean
{
//some method declare
}
