显示类似
HTTP Status 500 - /ora/ch5/easy.jsp (line: 13, column: 16) According to TLD or attribute directive in tag file, attribute value does not accept any expressions
错误
解决方法：
在jsp文件中
添加<%@ page isELIgnored="true"%>
<%@ page contentType="text/html" %>
<%@ page isELIgnored="true"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<html>
<head>
<title>JSP is Easy</title>
</head>
<body bgcolor="white">
<h1>JSP is as easy as ...</h1>
<%-- Calculate the sum of 1 + 2 + 3 dynamically --%>
1 + 2 + 3 = <c:out value="${1 + 2 + 3}"/>
</body>
</html>
Jsp设计第二版书中
貌似是JSTL的问题
