1、错误描写叙述

2014-7-13 2:38:54 org.apache.jasper.compiler.TldLocationsCache tldScanJar

信息: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

2、错误原因

      无法找到Action路径，页面引入Action的路径有问题



3、解决的方法

     在页面引入一个路径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请求时

$(function(){

	           $.ajax({

	               type:"post",

	               url:"${bp}/action/student/findStudent.action",

	               dataType:"json",

	               success:function(data){

	               }

	           });

		});

路径前加上“${bp}”
