Run javafx jar as sudo: Unable to open DISPLAY

I'm building a spring based javafx application which is aimed to run both on Linux and Windows machines.

I've encountered an error, and couldn't find a satisfying solution to the problem.
While trying to run the command sudo java -jar MS.jar, I'm getting InvocationTargetException:
Caused by: java.lang.UnsupportedOperationException: Unable to open DISPLAY

Of course, while executing java -jar MS.jar alone, everything works great.

BTW, Running echo $DISPLAY in terminal results with ":0"

The software is a javafx UI software, which needs sudo privileges for kernel tasks.

Machine details:
OS: OpenSuse 42.1
JAVA version: "1.8.0_152"

How can I resolve this issue?

Thanks!

Solution

  • Have you tried any of gtksudo/gtksu/kdesu

    commands instead of sudo?

    If your app is a UI app that should do the trick.
