I have deployed a Web Service with JbossWs on a Jboss-4.0.5 Server and it works

But now, I have to deploy the same Web Service on a Tomcat Server

I've installed JbossWs on my Tomcat like this:
http://labs.jboss.com/jbossws/user-guide/en/html/installation.html

and I've deployed my Web Service but it doesn't work

Could anyone explain me the deployment process on Tomcat? I haven't find it
