I am a JavaEE developer with not a big experience with deployment and server administration. And this is the point when your expertise plays a big role. I have a VPS (Ubuntu 16.04) and i want to run an ApacheTomcat server. The problem is when i edit the ports in the [url removed, login to view] file and i set the port 80 (and 443) instead of the default 8080. I see the logs and the following error appears " SEVERE [main] [url removed, login to view] Failed to initialize end point associated with ProtocolHandler ["http-nio-80"]
[url removed, login to view]: Permission denied
". I have tried to edit the iptables but with no success, and of course appending :8080 is not a solution. To notice is that i have uninstalled the Plesk Admin tool, which run on port 80.
