弄了好半天都是这样，HTTP Status 404 - 

解决方案 »

  1.   

    web.xml配置文件里引用struts.xml了吗？
      

  2.   

    <action name="kk" class="com.yuxuan.chain2">
            <result type="chain">/jsp/chain2.jsp</result>
        
        </action><package name="bb" namespace="/a" extends="struts-default">    
            <action name="check">
        <result>/jsp/checkbox.jsp</result>
        </action>
    大哥是不是少了一个类的路径
      

  3.   

    <action name="check" class=?>?????
      

  4.   

     <action name="dd">
       <action name="check">
    这两Action都没有写class
      

  5.   

     <action name="dd">
            <result>/jsp/a.jsp</result>
     </action>
    action对应的类。。
      

  6.   

    看异常是这样的，，你没有给action元素设置一个name属性。
