Hi Eric,
the awt code always tries to connect to an X server. If the machine your
program is running on has an X server running but you cant't connect
it's because as a telnet user you don't own the console and therefore
are not allowed to connect (it may be that you want to supervise other
user's work, which is normally not desired). The solution reported to
work on this list several times even if there is no X server at all is
to use the virtual frame buffer X server. This is a program that acts
like an X server to its clients, but has no real display. The name of
the program is xvfb, if I recall correctely.
