How to run glassfish 4 on port 80 instead of 8080? root access is not an issue

To run GlassFish on port 80 you need to :

  1. Connect to the administration interface (by default on port :4848)

  2. In the left menu go to Configurations

  3. Then select the appropriate configuration you need to change eg server-config

  4. Then go to Network Config

  5. Then go to Network Listeners

  6. Select the appropriate listener, probably http-listener-1

  7. Change the Port value to 80

  8. Save and reboot your GlassFish server/instance/cluster according to your needs

Using the command line utility

asadmin set 

you may need to replace server-config and/or http-listener-1
