Here is a very simple application of xml tags in JSTL.
****************************************
<%@ page language=”java” import=”java.util.*” %>
<%@ taglib uri=”http://java.sun.com/jstl/core_rt” prefix=”c” %>
<%@ taglib uri=”http://java.sun.com/jstl/xml_rt” prefix=”x” %>
<%@ taglib uri=”http://java.sun.com/jstl/fmt_rt” prefix=”fmt” %><jsp:useBean id=”today” class=”java.util.Date” />
<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”>
<html>
<head>
</head><body>
<x:parse var=”doc”>
<person>
<firstname>Sue</firstname>
<lastname>Tillman</lastname>
</person>
</x:parse>
Hello <x:out select=”$doc/person/firstname” /></body>
</html>***********************************
However, when I run it, I get the following error. I don’t get it. I have read several books and according to them, this example should work fine. Why does this not work and how do I fix it?
