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

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

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

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}" />.
