I'm attempting to start spring from Jetty, however I get the following error:

I use the following web.xml

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

<web-app xmlns="http&#58;//java.sun.com/xml/ns/j2ee"
	 xmlns&#58;xsi="http&#58;//www.w3.org/2001/XMLSchema-instance"
	 xsi&#58;schemaLocation="http&#58;//java.sun.com/xml/ns/j2ee http&#58;//java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
	 version="2.4">
         
    <!-- The spring servlet for MVC -->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- map HTML to spring, all HTML will eventually be mapped to a velocity template -->
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>    
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
    <welcome-file-list>
	<welcome-file>
            index.html
        </welcome-file>
    </welcome-file-list>
</web-app>

Anyone know why this happens? And what I can do to resove it. The idea is to use Jetty as a servlet container, spring as MVC and Velocity for the view.

Thanks in advance,
Vincent
