X server problem
 

I have this problem using linux(using Suse 9.3) and have a test program (graphics) graph.class, when I run it I get this error
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

at JPanels.main(JPanels.java:11)
If I run it on the linux machine, it runs fine, but when I ssh into the box and try to run it I get this error. Y is this so an any solution.
