Are you using a JSP 2.0 container (like Tomcat 5)? If not, you can't use JSTL
1.1, you have to use JSTL 1.0. For a quick sanity check, what do you get with
the following:
<h1>JSTL: <c:out value="${lvform.map.method}"/></h1>
<h1>Struts: <bean:write name="lvform" property="method"/></h1>
If you really are using a JSP 2.0 container, you can also try:
<h1>JSP: ${lvform.map.method}</h1>
Also make sure you're using a Servlet 2.4 deployment descriptor:
<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>
