  • I am also interested in this. I have a Java application deployed as a JAR file. I would like it to run all the time even when I am not logged on to my Ubuntu droplet.

    Any ideas?

Let me know if I am not understanding. As I understand your question you...

Have a jar you are running directly.

Want this jar to be launched (as a daemon?) automatically on boot (act as a service)

You want the service to be triggered based on the runlevel reported by linux

  • 3 Multi-User Mode with Networking Starts the system normally.
  • 4 Undefined Not used/User-definable
  • 5 X11 As runlevel 3 + display manager(X)
  • 6 Reboot Reboots the system

I assume this means you want something to happen based on whether the server is in multi-user mode, single-user mode or in a Graphical environment?

If that is the case, the current runlevel can be determined with the command runlevel so you could pretty easily script different actions based on the runlevel. I'd be happy to help you put together a basic script if you can share a little more information on what outcome are looking for.

  • I only want to run my jar as a service, i will manual assign run level to the service, i want something like in Ubuntu 12.04 i created one config file having content run level,description and command to run java jar and then i placed it in /etc/init/ and this config file directly run my jar as a service.
    Thank You
