问题
Did some google on it and the solution was to redirect using iptables or mod in apache? Since my application uses websockets the above solution breaks my websocket connectivity and I again have to connect to my websockets using port 8080. Is there any way that I can run the glassfish itself on port 80 so that my websockets also run on port 80 making easier for users behind corporate firewall to access the app since corparates may block 8080.
I have root access as well.
回答1:
To run GlassFish on port 80 you need to :
Connect to the administration interface (by default on port :4848)
In the left menu go to Configurations
Then select the appropriate configuration you need to change eg server-config
Then go to Network Config
Then go to Network Listeners
Select the appropriate listener, probably http-listener-1
Change the Port value to 80
Save and reboot your GlassFish server/instance/cluster according to your needs
Using the command line utility
asadmin set configs.config.server-config.network-config.network-listeners.network-listener.http-listener-1.port=80
you may need to replace server-config and/or http-listener-1

Go to glassfish4\glassfish\domains\domain1\config folder and here open domain.xml file
and find tag
<network-listeners>
<network-listener port="9999" protocol="http-listener-1" transport="tcp" name="http-listener-1" thread-pool="http-thread-pool"></network-listener>
</network-listeners>
in port attribute of <network-listeners> you can specify your port address whichever you want.

Here's another approach.
You can go to the admin console under port 4848 (I am using Glassfish 4.1.2) and navigate to "Configuration" > "server-config" > "HTTP Service" > "Http Listeners" > "http-listener-1" in the left hand navigation.
Click on the "http-listener-1" link in the main content window.
Change the port to desired number and save.
Restart Glassfish and run your application.

in some cases you have to change port before glassfish is started (in my case port 8080 is already in use by another instance) so answer 4 worked for me.
