Nevíte někdo čím může být tato chyba způsobena? Co dělám špatně? Ve web.xml mám toto:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

a ve struts.xml toto:

>?xml version="1.0" encoding="UTF-8"?<
>!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"<

Máš přiložen struts2-convention-plugin-2.1.6.jar plugin v WEB_INF/lib ? Mnoho úspěchů při studování VŠB přeje absolvent:)
