We all know the deployment of servlet could be very messy, especially you port application from one web server to a different web server. For complicated application, this book didn't give clue of how to deploy, say, chat server on popular web servers such as apache with Jserv. I found it difficult to put his chat room server to work on apache. Although "Hello world" servlet works, it really doesn't matter to me because this is a small toy application only. Anyone tried to deploy his chat room servlets working on appache and could share with us how to do it?
