By default Glassfish listens to http on port 8080 and https on port 8181.
It is better to listen to the default ports 80 for http and 443 for https, usually you dont want the user to enter port numbers as part of the URL.
Even the Glassfish Admin Console allows to change the ports (Configurations/Server Config/Network Config/Network Listener), certain server OS such as Ubuntu do not allow non-root users (you should run Glassfish as separate user !) to ports below 1024. We can achieve this by port rerouting with the iptables command (under Ubuntu)
iptables -A INPUT -p tcp --dport 80 -j ACCEPT iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 8080 iptables -A INPUT -p tcp --dport 443 -j ACCEPT iptables -t nat -A PREROUTING -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 8181 iptables-save -c > /etc/iptables.rules iptables-restore < /etc/iptables.rules vi /etc/network/if-pre-up.d/iptablesload #!/bin/sh iptables-restore < /etc/iptables.rules exit 0
Additionally you can get a proper SSL certificate to stop annoying the user with a no proper certificate warning. See previous tutorial here.
If you operate an enterprise application with a known URL to the users, unlike a regular website where the portal should be reached with regular http, I would completely disable regular http.
