[PLUG] service in systemd not starting custom java app after rebooting RHEL 7.4

[Amey Abhyankar]

Hello,

I am trying to create a service inside /etc/systemd/system & it's
softlink in /etc/systemd/system/multi-user.target.wants but it's not
helping.

After system reboot, if I do ps -ef |grep -i javaapp it's not started.

Can somebody suggest best practices to make custom java application as
a service using systemd?

My current config of service as follows =
I copied mongodb conf file and created new service using appropriate parameters.
