First of all, thank you for doing this. It’s a very helpful resource of information. Your way of presenting these ideas and concepts is very straightforward and clean. I was looking for this kind of resource for very long time.
Regarding the ‘Server Tutorial’: I try to complete the tutorial that explains how the ‘Servlet’ is working. I’ve successfully compiled the class, created the folder structure inside the ‘webapps’ folder, created the web.xml file. But when I go to ‘http://localhost:8080/HelloWorldWebApp/index.html’ I get this error message: “Service unavailable”.
If possible, please explain what is the reason for this.
