start, stop and reload glassfish 4.x on Ubuntu

this is a short post, if you've already downloaded and installed glassfish 4.x (most of the time at /opt directory), you may use these commands to work with it:

1. to start: sudo ./asadmin start-domain

2. to enable admin's page (at 4848 port): sudo ./asadmin enable-secure-admin

3. to restart: sudo ./asadmin restart-domain

4. to stop: sudo ./asadmin stop-domain

that's all

cheers
