JSTL forEach tag

Hi All,
I am using Tomcat 5.0.18 , WinXP and J2sdk1.4.2_03
I installed standard tag libray from jakarata.apache.org. following code snippet shows the use of forEach tag.
<%@ taglib uri="http://jakarta.apache.org/taglibs/core" prefix="c" %>
<html>
<head>
<title>Count to 10 Example(using JSTL)</title>
</head>
<body>
<c:forEach var="i" begin="1" end="10" step="1">
<c ut value="${i.value}" />
</br>
</c:forEach>
</body>
</html>
Now instead of priting values from 1 to 10 it prints {i.value} string !!!
why it is not priting numbers ???
Can anybody help
thanks

Anand,
you have to use <c ut value="${i}" />
not <c ut value="${i.value}" />

Hi Mouli,
I tried <c ut value="${i}" /> but same problem !
It gives {i} in output and not the values of i !
thanks

try this instead.
It might still not work as c:forEach iterates over a List and you supply a List (but this might be a form I haven't seen before).

By default, the EL evaluation is enabled for Web Applications using
a Servlet 2.4 or greater web.xml, and disabled otherwise.
you can make your web.xml like this to enable EL:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-app_2_4.xsd"
version="2.4">
</web-app>
and BTW: you can just use ${i} instead of <c: out value="${i}" />.
