Pass variable in tag file JSP

Question

I want to pass a variable in tag file. My code here:

layout.tag

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@tag description="My layout" pageEncoding="UTF-8"%>
<%@attribute name="title" type="java.lang.String" required="true" %>  
<!DOCTYPE html>
<html>
<head>
    <title>My site | <c:out value="${title}" /></title>
</head>
<body>
</body>
</html>

index.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="mySite" tagdir="/WEB-INF/tags" %>
<mySite:layout title="home">
</mySite:layout>`

But <c:out value="${title} />" always return ${title}. I tried with ${title} and got the same result. I dont know why...

It works for me. What container are you using and what version is it at? — Sotirios Delimanolis, Mar 24 '14 at 03:04
@SotiriosDelimanolis I'm using maven and Java 1.7. I use `<%= title %>` and it works... — ducdhm, Mar 24 '14 at 03:52
What Servlet container are you using? Tomcat? What version of it? — Sotirios Delimanolis, Mar 24 '14 at 03:53
check in target folder or war file in WEB-INF/lib if you have el jar library — Ravi Kumar, Mar 24 '14 at 07:07
I saw el-api-2.2.jar in Maven Dependencies. But it still doesnt work — ducdhm, Mar 24 '14 at 07:27
