2、没有jstl架包。下载jstl架包，引入；如果是maven项目引入

<groupId>javax.servlet.jsp.jstl</groupId>

</dependency>

3、jsp也买你引入

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

4、就可以使用jstl标签了。

<c:set var="ctx" value="${pageContext.request.contextPath}" scope = "request"/>
