When you are running on a Unix platform, you must have an X-Windows server
running in order for AWT to work, and the username you are running your
servlets under must have permissions to connect to it. This is true even if
you are not displaying anything graphical on the server's console.
For the gory details, you'll have to ask someone else (I haven't yet needed to
create images dynamically), but this question regularly comes up for both
servlets and standalone Java applications.
