I'm feeling a little bad about the guy in my writing seminar who I said was full of crap, because I think he's caught on to the fact that I don't like him too well and now he seems kind of... aloof/mean.

Oh, thats not a bug in your program :-).

"Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable." - means that there is no GUI running on "yuma." You need a GUI to display windows drawn by AWT.

(i) If you are sitting behind a *NIX machine with a GUI, run "ssh -X myusername@yuma.princeton.edu" instead of "ssh myusername@yuma.princeton.edu."

(ii) If you are sitting behind a Mac OS X box, open up an XTerm (Thats that X11 icon down there on the dock), and do the same thing as in (i)

(iii) If you are sitting behind a Windows box, you will need to install an X server on your box (or start one, if your lab computers have it - Hummingbird eXceed or MI/X). Then tell puTTY to forward X.
