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

Here is the error I have when I install pja.jar in my $TOMCAT_HOME/lib,
and 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!!!
