Add the following contents to the file:

[Unit]
Description = GlassFish Server v7.0
After = syslog.target network.target [Service]
ExecStart=/opt/glassfish7/bin/asadmin start-domain

Type = forking [Install]
WantedBy = multi-user.target

When you are done, save and close the file.

Next, you need to reload the system services with the following command:

sudo systemctl daemon-reload

Now you can start and enable GlassFish to start on boot with the commands below:

# sudo systemctl start glassfish
# sudo systemctl enable glassfish

Verify that your GlassFish service is active and running on Ubuntu 22.04 with the following command:

sudo systemctl status glassfish

Output

GlassFish Configuration on Ubuntu 22.04

The default GlassFish admin password is blank. For more security, you can set a password for your GlassFish admin user.

GlassFish has a tool called asadmin that accepts commands for setting up GlassFish via a command line.

To make this command executable anywhere, run the following command:

export PATH=/opt/glassfish7/bin:$PATH

Now you can use the following command to set a GlassFish admin password:

asadmin --port 4848 change-admin-password

You will be asked to enter the admin password, press enter to set a new password.

Enter admin user name [default: admin]>admin
Enter the admin password> press enter
Enter the new admin password> set a password
Enter the new admin password again> re-type password

Output
Command change-admin-password executed successfully.

Next, you need to enable the secure admin feature with the following command:

asadmin --port 4848 enable-secure-admin

You should enter your admin username and password then, in your output, you will see:

Output
Command enable-secure-admin executed successfully.

Now restart GlassFish on Ubuntu 22.04 to apply the changes:

sudo systemctl restart glassfish

Configure Firewall for GlassFish

If you have a running firewall, you need to allow the following ports through the UFW firewall:

# sudo ufw allow 4848/tcp
# Sudo ufw allow 8080/tcp

Reload the firewall to apply the new rules:

sudo ufw reload
