X11 on server without forwarding

Question

I'm running a java application on my ubuntu server which refuses to open if it cannot open a window (the content of the windows is of no interest for me). Since the server is not connected to any screen I don't want to have a full running x11 environment like openbox. Currently I'm forwarding this window over ssh to my pc but this way the program closes whenever I'm rebooting the pc. What could be a good solution for this? (I'll never need to see the content of the window)

Is there an option on the command line to disable this requirement? — Karlson, Sep 19 '12 at 17:10

Xvfb is an X server intended for situations like yours.

Debian and Ubuntu's xvfb package includes a script, xvfb-run, which will automatically launch an Xvfb instance and run your program with $DISPLAY pointing to that instance. – Jim Paris Sep 19 '12 at 18:37

You have to use a headless jre, e.g. the package default-jre-headless.
