I presently am having difficulty using the awt with servlets to do image
reconstruction work on a RedHat 7.2 Linux platfrom, because I get the
following exception, which some think is a bug in JDK 1.4, but seems to be
something Sun has tolerated intentionally
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 sun.awt.X11GraphicsEnvironment.initDisplay(Native Method)

My "ps aux" says:
/etc/X11/X -auth /var/lib/kdm/authfiles/A:0-0Dqymv
for the X11 server. Does anyone have an idea what I need to do at this
point? Everything works on a pc, of course.
This is not strictly a struts problem, of course, but it is something that
struts users that deal with multimedia will need to deal with since it is
essentially a server side problem. I have no problem with leaving an X11
server running to make this work. I cannot live with the client having to
do anything special. The problem is that I don't want to use the graphics
but do want to access the graphic functionality.
Thanks for any assistance.

P.S. If you don't understand the above, please do not offer
suggestions. Thanks for that too.
