off screen image

[ncubukcu]

if I remotely connect to my visad server and run a test program that 
constructs something like following;
DisplayImplJ2D display = new DisplayImplJ2D("display1",300,300);

this is what I get when I run my code;

kCGErrorRangeCheck : Window Server communications from outside of 
session allowed for root and console user only

*I know why I get this exception.. it want's me to run it in headless 
mode or I have to set  display to my local machine.  What I don't 
understand is why the off screen constructor above needs a display. Any 
idea how I can go around this. I have done all my excercises on a local 
machine but now that I need to use remote machine for visad, all my test 
cases are failing...
thanks
