    Post Setting X11 DISPLAY variable


    Hello,

    I have tried to execute a jar file from the command line, and I got the follwing error:

    java.awt.HeadlessException:
    No X11 DISPLAY variable was set, but this program performed an operation which requires it.

    Where should I set the variable (or what could be done)? Thank you.
