Hi All
can any body please tell me how to add an ArrayList object to request scope using set tag
My code is as below



<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page isELIgnored="false" %>
<%@ page import="java.util.*" %>
<%
ArrayList a=new ArrayList();
a.add("one");
a.add("two");
a.add("three");
a.add("four");

%>
<c:set var="aaa" value="${a}" />
<c:forEach var="i" items="${aaa}" >
<c:out value="${i}" />
</c:forEach>


After executing above jsp I am getting blank value in browser

Thanks in advance

If you want to do it within a Java scriptlet (not a good idea) then you would do exactly as you would do it within a servlet (which is a better idea anyway).

From java code, you add an item to request scope by calling request.setAttribute method.

In your case request.setAttribute.("aaa", a);


${aaa} evaluates as pageContext.findAttribute("aaa") and would thus then find your request attribute.

Using scriptlets in a JSP ia bad idea.

Mixing scriptlets with JSTL and EL code is even worse, and nothing short of madness.

Stop the madness.
