这个是j2eejava web 编程精要十五讲的全部源码。对学习java web编程的人来说是很能得的资料

package login;

import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.util.*;

public class loginAction extends Action {
  public ActionForward execute(ActionMapping actionMapping, ActionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
    /**@todo: complete the business logic here, this is just a skeleton.*/
    loginActionForm loginForm = (loginActionForm) actionForm;

    String username = loginForm.getUsername();
    String password = loginForm.getPassword();

    //生成一个ArrayList对象，并把用户名和密码的值存入该对象中
      ArrayList arr = new ArrayList();
       arr.add(username);
       arr.add(password);

       String prompt;

      //调用模型组件loginHandler，检查该用户是否已注册
       loginHandler login = new loginHandler();
       boolean mark = login.checkLogin(arr);



       if(mark)  prompt = "Success";
         else prompt = "Fail";

      return actionMapping.findForward(prompt);

  }
