If EL expressions are not being evaluated, you may have a set up problem. See the JSP FAQ for information on properly setting up a JSP 2.0 web application.

What container and version? What is the declaration at the top of your web.xml?

Did you check to see if your list is getting populated? And also is the forEach getting executed? I mean if you give something like this, is it working?

<c:forEach items="${expTypes}" var="expenseType">
Hello
</c:forEach>

Thanks for taking time for me



first reply to Bear Bibeault

i am testing this application on both

jboss-4.0.2 and Apache Tomcat 5.0


declaration at the top of my web.xml is

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<!--##################taglibs used in the application#######################-->
<taglib>
<taglib-uri>/spring</taglib-uri>
<taglib-location>/WEB-INF/tld/spring.tld</taglib-location>
</taglib>

<taglib>
<!-- <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>-->
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/tld/c.tld</taglib-location>
</taglib>




part of my c.tld file is

<?xml version="1.0" encoding="UTF-8" ?>

<taglib 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 http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
version="2.0">

<description>JSTL 1.1 core library</description>
<display-name>JSTL core</display-name>
<tlib-version>1.1</tlib-version>
<short-name>c</short-name>
<uri>http://java.sun.com/jsp/jstl/core</uri>

Your web.xml declaration is wrong. In order to enable the EL outside of the JSTL tags (like <cut>) you must declare your web.xml using the Servets 2.4 XML Schema.

See the JSP FAQ for details.

bear is right
you have to use

<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 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">

one more thing

is map is set as attribute

pageContext.setAttribute("map", yourmap);
