Getting sum using EL and JSP - 


<%     double sum = 0.0; %> <c:foreach var="user" items="${page.content}">     <%         sum += $user.grade;     %>     ${user.grade} </c:foreach>

i want sum of user.grade. how it?

don't mix jstl scriptlets. actually, don't use scriptlets @ all.

<c:set var="sum" scope="page" value="0.0"/> <c:foreach var="user" items="${page.content}">     <c:set var="sum" scope="page" value="${sum + user.grade}" />     ${user.grade}<br/> </c:foreach>

better yet, summation in controller.
