This is the content of the web.xml (I copied it from portlet testsuite):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

        <servlet-name>contentviewer</servlet-name>

        <description>Automated generated Portlet Wrapper</description>

        <init-param>

    <servlet-mapping>

	</servlet-mapping>
 
</web-app>

And this is the tomcat output:
