Hi There,
I've created MyFirstStrutsPage.jsp:
<%@ page language="java" %>
<%@ taglib uri="/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/struts-html.tld" prefix="html" %>
<%@ taglib uri="/struts-logic.tld" prefix="logic" %>
<html:html locale="true">
<head>
<title>Test Struts Page</title>
<html:base/>
</head>
<body><bean:message key="index.text1" /></body>
</html:html>
and my web.xml is as followed:
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="_http://java.sun.com/xml/ns/j2ee_

and i've created ApplicationResources.properties with the following entries:
index.title = My first Struts application!
index.text1 = This is my first Dynamic Struts application.
However, when i request MyFirstStrutsPage.jsp is get the following error (
what have i done wrong, any ideas on how to fix it?):
