JSP Page display date from collection

I am new to JSP and servlet.

I am trying to have list from servlet and wants to display those data into JSP page.

Here is what I did

My Servlet class

List<User> list = friendsDao.getFirendsList(user.getEmail());
System.out.println("List Size:"+list.size());
req.setAttribute("list", list);
getServletContext().getRequestDispatcher("/home.jsp").forward(req, resp);

My JSP Page

I have added this tag library

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

and here is what I am doing to iterate the data

<table>
    <c:forEach var="friend" items="${list}">
        <tr>
            <td><c:out value="${friend}" /></td>
            <td><c:out value="${friend.email}" /></td>
        </tr>
    </c:forEach>
</table>

but this is not working

but when I am trying to have something like this

<%
    }
    List<User> list = (List<User>) request.getAttribute("list");
%>


    <table>
        <c:forEach var="friend" items="<%=list%>">
            <tr>
                <td><c:out value="${friend.name}" /></td>
                <td><c:out value="${friend.email}" /></td>
            </tr>
        </c:forEach>
    </table>

This is also not working but, it at list iterate the loop to the size of data. but in browser it prints

${friend.name} ${friend.eamil}

How can I have actual values in there. Please help me with this.

Thanks, Nixit

Ohk I got the solution,

I don't know the reason, but jsp file requires me to put this one line of code. in order to tag library to work

<%@ page isELIgnored="false" %>

change 

    <c:forEach var="friend" items="<%=list%>">

to

    <c:forEach var="friend" items="${list}">

because by <%=list%> it is outputting the value right there, and you don't need reference to List<User> in jsp
