I do this all the time but you have to be careful as to what code you
run. If it does anything graphics related (such as images or swing or
user input) then you will need X.

Why are you creating a JSliderBar? This is a GUI item and if you are
a service (non-GUI) I don't know where that component would be useful.
Anyway, if you really need to create such an object you will need some form
of X environment, even if it is a simple frame buffer (such as Xvfb)
