在JavaWeb开发中，常使用绝对路径的方式来引入JavaScript和CSS文件，这样可以避免因为目录变动导致引入文件找不到的情况，常用的做法如下：

一、使用${pageContext.request.contextPath}

　　代码” ${pageContext.request.contextPath}”的作用是取出部署的应用程序名，这样不管如何部署，所用路径都是正确的。

例如：

1 <!--使用绝对路径的方式引入CSS文件-->
2 <link rel="stylesheet" href="${pageContext.request.contextPath}/themes/default/css/ueditor.css" type="text/css"/>
3 <!--使用绝对路径的方式引入JavaScript脚本-->
4 <script type="text/javascript" src="${pageContext.request.contextPath}/ueditor1_3_6-gbk-jsp/ueditor.config.js"></script>

使用<%=request.getContextPath()%>和使用${pageContext.request.contextPath}达到同样的效果

<script type="text/javascript" src="<%=request.getContextPath()%>/ueditor1_3_6-gbk-jsp/ueditor.all.js"></script>

实战项目：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ include file="../include/header.jsp"%>
<html>
<head>
<%@ include file="../include/footer.jsp"%>

<script type="text/javascript">

	function formateTd(value,row,index){
		var operator = $("#operator").val();
		return findBpmViewName(operator,row.processInstanceId);
	}
	
	function detail(processInstanceId){
		var path = '${pageContext.request.contextPath}/posRepairBill/toPosRepairAdd?processInstanceId='+processInstanceId;
		window.location.href = path;
	}
	
</script>
</head>
