You must create a systemd service file. Here is the format for one using standard paths:
# Qvera Interface Engine
[Unit]
After=mysql.service
[Service]
ExecStart=/java/qie/start.sh
[Install]
WantedBy=default.target
Save this file in /etc/systemd/system
*Note: if you do not use MySQL/MariaDB, or it is not installed on the same system, you may replace the "After" line with this:
After=network.target
