Solution 1 : using PJA as an alternative to built-in AWT.
PJA does not require a X server to launch

Solution 2: removing any reference to SVG and PDF.
This should disable any call to Batik, which is the problematic library,
requiring the X11 display
***
Removing anything concerning SVG does not solve the problem, in the
sitemap.xmap and the WEB-INF/.
May be I missed something.
But I still have a SVGBuilder trying to instanciate a batik
SVGDOMImplementation, which requires a X11 display.
Note that serializer related to SVG, PDF and XML are disabled!!!

Stop your servlet container, remove all work directories and restart. Be
sure to remove any references to svg in the sitemap, besides the
serializers there are samples referring to it.
I have C2 running on a Solaris server without any display or X server,
using Tomcat 3.2.3, so it must work.
Solution 3: use Xvfb if it is available on your platform. I use it on my
development Linux box because, even though I have an X11 display,
whenever I logout the X server is restarted and Tomcat just crashes.
Took a while to figure out why I had to restart Tomcat every morning :).

I understand that PJA is quite old, so I'm not surprides to see this.

Here an SVG serializer is instantiated, and this causes the problem.
Since "svg2jpeg" is next to the latest one who was instantiated
correctly in the default sitemap, can you please double check that you
removed that one too?
I'll do some tests tomorrow too, and let you know.
Ciao,
