JSTL错误：绝对uri：http://java.sun.com/jsp/jstl/core不能在web.xml或与此应用程序一起部署的jar文件中解析

Question

Here's my code:

<%@ page import="java.io.*,java.util.*,java.sql.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>

Followed by the html file. jstl-1.2.jar is located in the WEB-INF folder. That is the only explanation I've found anywhere else for why this shouldn't work, so I don't understand why I am still having this problem.

Answer 1

Tags are correct.

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

Where in WEB-INF folder it should be under lib.

Answer 2

我使用的JSP版本与JSTL版本不兼容。
