    Installation of jBPM 3.3.0 GA on a headless linux box

    Rob Burnett Newbie

      Hi there,

      I just tried installing jBPM 3.3.0 on a headless Linux box and it complains about not finding a X11 display variable (exact error is below)
      Is there a way to install this release with out using the graphical interface?
      Any suggestions would be appreciated.

      Thanks!


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