I think the idea is that you just need to do a:
$ export CATALINA_OPTS="-Djava.awt.headless=true"
$ bin/startup.sh
No need to actually modify the catalina.sh code, it will
automatically pick up the environment variable. I just tried
it with code like:
BufferedImage bi = new
BufferedImage(128,128,BufferedImage.TYPE_INT_RGB);
Graphics2D g = bi.createGraphics();
g.drawLine(0, 0, 120, 120);
Raster r = bi.getData();
rsp.setContentType("image/jpeg");
JPEGImageEncoder ie = JPEGCodec.createJPEGEncoder(rsp.getOutputStream
());
ie.encode(bi);
and it worked fine.

Are you trying to create a Frame? Heavyweight components
are always going to throw HeadlessExceptions, ref:
