Hi there.


I do not know why I keep getting "404 The requested resource is not available", when I am accessing my GWT Application. I am hosting my GWT application, on my TomEE/8.5.6 (7.0.2) at home, currently.

Here is the situation.

  1. I am able to use my GWT application from "TomEE Web Application Manager" as (http)://192.168.1.70:8080/Index

  2. However, when I type (http)://www.zethanath.tk in the browser, I would get (https)://www.zethanath.tk/ with HTTP Status 404.

Here is the details of my configuration.

I keep thinking that I need to associate port 8080 with "DocumentRoot "/opt/tomcat/webapps/Index", but I am unsure how.

Here is the details of my UFW. I have similar setup in the router.

Help is greatly appreciated.
