Error 404 running Servlet with Tomcat 4.1.18

Question

Hi,
I made a small test servlet in a "hello world" style and I have problems to make it run under Tomcat 4.1.18 whereas it works perfectly on Tomcat 3.3 and Tomcat4.0.6...
Why do I get a 404 error with 4.1.18 whereas I can reach the servlet on other versions of Tomcat ??
Do you have an idea ?
Is there some new tricks in 4.1.18 ?
Thanks

Here is my web.xml, i put it in the directory of tomcat\webapps\myApp\WEB-INF :
<?xml version="1.0" encoding="ISO=8859-1"?>
<!DOCTYPE web-app
     PUBLIC "-//Sun Microsystem, Inc.//DTD Web Application2.3//EN"
     "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
     <servlet>
     <servlet-name>myservlet</servlet-name>
     <servlet-class>TestingServlet</servlet-class>
     </servlet>
</web-app>
and still it doesn't work...
