sd_notify() from Java

Question

I have a Java service (implemented using Dropwizard) which I\'m launching from a user instance of systemd. So far so good. Now I would like to use systemd\'s notification feat

Answer 1

I found this implementation which does use system hooks, but at least doesn't require JNA/JNI.

As you say, systemd uses sockets referenced by an environment variable (System.getenv("NOTIFY_SOCKET") in the code), so I'd imagine there may also be a way to use a Java Socket, although I'd imagine a lot of research and/or trial-and-error would be required.
