出现上述错误的原因是,在JSP页面使用了fmt标签库
原因:

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>
//使用了日期格式化方法
<fmt:formatDate pattern="yyyy-MM-dd" value="${user.birthday}" />

出现错误的原因是使用的是jstl1.2,在jstl1.0和jstp1.1、jstl1.2版本在使用标签库的时候存在一定的差别,在jstl1.0以后的版本uri都应该加上/jsp,引用方法如下:
解决方法一:(推荐)

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
//使用了日期格式化方法
<fmt:formatDate pattern="yyyy-MM-dd" value="${user.birthday}" />

解决方法二:
修改web.xml和jstl库版本

//修改2.3以上版本为2.3及以下版本版本
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         id="myweb" version="3.0">
