I seem to be having great difficulty setting up Xvfb and DISPLAY to
generate images from a servlet.
I've tried this tip I found on the JServ site:

> classes=$CLASSPATH:$jsdk:$jserv

But to no avail (I'm still getting a "no awt in shared library"
message).
Can anyone assist? Specifically, does anyone know how to set
environment variables from within a servlet?
