Tomcat version ???
JSTL version ???
web.xml ???

-------------------------------------------------------------------------------------------------------
On Tomcat 5.5 , JSTL 1.1 web.xml version 2.4 the following works.
But it won't work in a web.xml using version 2.2
-------------------------------------------------------------------------------------------------------

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<jsp:useBean id="myMap" type="java.util.Map" class="java.util.HashMap"
scope="session"/>

<c:set var="keyVar" value="planet"/>
<c:set var="valueVar" value="Earth"/>
<c:set target="${myMap}" property="${keyVar}" value="${valueVar}"/>

${myMap[keyVar]}

I mentioned before that DataGrid uses web.xml of version 2.2

but JSTL 1.1 Expression Language requires a web.xml of version 2.4

So you would need to compromise somewhere


1)  (from my understanding), you would need to probably downgrade to
the JSTL to  JSTL 1.0 or lower , research on which version of JSTL is
compliant with JSP 1.2 and what syntax is used in EL if you are taking
this route.

--- I only know EL syntax for JSP 2.0 (Tomcat 5.5.x) , I don't know if
the EL syntax is different for lower versions of JSP 1.2 etc.
