unable to iterate through list - JSTL

Question

servlet code :

     List<Uscensuspopulationdata> ls = query.list();

      request.getSession().setAttribute("out", ls);
      response.sendRedirect("fulldata.jsp");

JSP code: //out has represents the entire list. so out[0].name works. //but i dont know how to iterate to display all the records

       ${out[0].name}

I want to display something like this: ${out[i].name} inside a loop so that i can get all the names from the list

Put your mouse on the `[jstl]` tag below the question until a black box pops up. Click therein the *info* link. Take your time to read it carefully. — BalusC, Oct 17 '12 at 02:27

You would use forEach:

<c:forEach items="${out}" var="theItem">
  <c:out value="${theItem.name}" />
</c:forEach>

Did you declare the `c` taglib in your page? If you view the source of the produced HTML and you still see ` – Jasper de Vries Oct 19 '12 at 13:02

Since you've posted it on the session, try explicitly declaring the list in the session scope via ${sessionScope...

<c:forEach items="${sessionScope.ls}" var="e">      
    ${e.name} <br> 
</c:forEach>

Didn't you forget to add declaration <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
