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"

</servlet>
<servlet-mapping>
<servlet-name>contentviewer</servlet-name>
<url-pattern>/PlutoInvoker/HTMLContentViewerPortlet</url-pattern>

And this is the tomcat output:
