I've wrapped a jar in a init.d service following the guide here.

  • created the service file under /etc/init.d/
  • give proper permissions
  • test the stop and start: sudo service myservice start/stop/restart;

The process is starting after the sudo service myservice start and I can see it from the command ps -ef | grep -i myservice However the service should log its execution in a logging file in the same path of the jar, but this logging file is not created.

Instead, If the jar is executed through java -jar myJar.jar & and not within the service the log file is created.

How is it possible?

Thanks Simone

  • Does the user account which is running the java program have read-write access to the log file? – Emmanuel Rosa Oct 8 '18 at 7:38

    That wrapper appears to be only for creating a pid/starting a java program, and you v talk nothing about what you are doing to generate logs. Have you also did the modification there – Rui F Ribeiro Oct 8 '18 at 7:59

    You are asking people to debug the arbitrary coded behaviour of a program that they do not know, with zero information about that program. Answerers do not know all of the things that a program's built-in idiosyncratic logging system might be sensitive to. That's not a particularly good van Smoorenburg rc script example to be following, either. – JdeBP Oct 8 '18 at 8:02
  • @EmmanuelRosa by the looks of the unit, root. – Rui F Ribeiro Oct 8 '18 at 8:04

    (And its supposed systemd update is an example of how not to run Java services under systemd, incorporating at least two of the House of Horror mistakes.) – JdeBP Oct 8 '18 at 8:06
