May I ask, how you did this ? I've also encountered

I added the headless flag to catalina.sh as follows:

Thanks Micael. Tried the same thing and got the same results.
Looks like Catalina/Tomcat is indeed using headless mode but
it's not working with my Java (1.4) and operating system (SunOS 5.6).
I'm presuming you're using this to create/generate graphics in a
servlet ? Do you mind posting sample
Here are two uses, if they are of help. I am using Red Hat 7.2 Linux.
FIRST:
public JPEGEncoder(Image image, int quality, OutputStream out) {
MediaTracker tracker = new MediaTracker(this);
tracker.addImage(image, 0);
try {
The material George gave you is really good. Do you have X11 installed,
even if not running? I am not a Solaris guy, so don't know what that may
mean in that context.

Hi all,
It have been a long time since I read any post... but I can't ignore someone in
trouble.
I had a similar problem using java.AWT with linux...
It needs a graphics system server, like windows or X11 running in your server.
But as X11 was too heavy for my system, my workaround was to start
Hey,
From the 1.4.x api docs:
HeadlessException: Thrown when code that is dependent on a keyboard,
display, or mouse is called in an environment that does not support a
keyboard, display, or mouse.
That Frame seems to be the culprit of this.

If I had to wager a guess you'll need to run tomcat in a 'headless' JVM.
To do that add :
-Djava.awt.headless=true
To the :
CATALINA_OPTS
environment variable.
