【JSP中引入文件】JSP中获取根路径+引用js文件

在jsp界面中经常需要引入js、css等文件，通常都需要先获取项目根路径，然后再引入文件。

例如：

项目路径如下，需要在index.jsp中引入FusionCharts相关的js、css等；

index.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
	response.setHeader("Pragma", "no-cache");
	response.setHeader("Cache-Control", "no-cache");
	response.setDateHeader("Expires", 0);
%>

<script type="text/javascript" src="<%=basePath%>fusionCharts/fusioncharts.js"></script>
<script type="text/javascript" src="<%=basePath%>fusioncharts/themes/fusioncharts.theme.fint.js"></script>
<link rel="stylesheet" type="text/css" href="<%=basePath%>css/uploadify.css"/>
<script type="text/javascript"></script>
</head>
<body></body>
