To display cookie value into a JSP, use this code:

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

<c:forEach var="cookieVal" items="${pageContext.request.cookies}" > 
    <tr>
        <td align="right">${cookieVal.name}</td>
        <td>${cookieVal.value}</td>
    </tr>
</c:forEach>

This piece of code was originally taken from this answer.

I hope this helps.
