<%@ page language="java" pageEncoding="UTF-8" contentType="text/html; charset=utf-8"%><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>用户按照所属单位分报表统计</title><LINK href="${pageContext.request.contextPath }/css/Style.css" type="text/css" rel="stylesheet"></head><body><fieldset style="width: 600px; height: 600px; padding: 1 background:${pageContext.request.contextPath }/images/back1.JPG"><legend><font color="#0000FF"><img  border="0" src="${pageContext.request.contextPath }/images/zoom.gif"    style="max-width:90%"  style="max-width:90%" alt="$变量 是web开发里的哪种语言_html/css_WEB-ITnose" > 报表统计</font></legend>			<img  src="${pageContext.request.contextPath}/chart/${filename}" border="0" alt="$变量 是web开发里的哪种语言_html/css_WEB-ITnose" ></fieldset></body></html>


如上页面里的${pageContext.request.contextPath }
这种用法是什么语言的?
有相关文章吗?

谢谢

这种表达是el表达式,jsp常用的一种数据读取,相关的用法你可以百度查一下有很多!
