解决方案 »

  1.   

    <html:form action="/HelloAction" method="post" focus="login">
    你检查下。看看
      

  2.   

    struts.bean 包不存在. 你把struts.bean 包放在lib包里
      

  3.   

    试一下这个。把你在struts的配置文件中的那句替换掉<form-bean name="HelloActionForm" type="ch2.HelloActionForm">
         <form-property name="login" type="java.lang.String" />
    </form-bean>
      

  4.   

    要是不行的话，你就得到具体的javabean中添加login成员，并加上set和get方法。
      

  5.   

    在类  ch2.HelloActionForm    中 属性login  没有set和get方法，
           public String getLogin() {
    return login;
    }
    public void setLogin(String login) {
    this.login = login;
    }  试试！
      

  6.   

    web.xml里添加
    你的struts 标签的引用
      

  7.   


    这样应该可以吧，错误提示是没有getter方法
      

  8.   

    把helloresult.jsp 中<bean:write name="form" property="login"/>给为
    <bean:write name="HelloActionForm" property="login"/> 就可以
      

  9.   

    有get 和 set方法啊，怎么还是不行？
