2、錯誤原因

      無法找到Action路徑，頁面引入Action的路徑有問題

3、解決的方法

     在頁面引入一個路徑jsp

<%@ include file="pathTags.jsp"%> 

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>  <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>  <%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>  <%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>  <%@ taglib prefix="m" uri="http://java.sun.com/jsp/jstl/functions" %>  <%  String path = request.getContextPath();  String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  %>    <c:set var="bp" value="<%=basePath%>"></c:set>  <c:set var="pa" value="<%=path%>"></c:set> 

   action請求時

$(function(){           $.ajax({               type:"post",               url:"${bp}/action/student/findStudent.action",               dataType:"json",               success:function(data){                                  }           });});

     路徑前加上“${bp}”

There is no Action mapped for namespace [/pages/action/student] and action name [findStudent]
