You either have no X server running or not the permissions to
connect to the server. The message appears whenever at least one servlet uses
direct or indirect SWING ( AWT) classes.

The second root may be followup error of the fact that it's not
possible to connect to the X server.
There occured an error during initialzation of the MToolkit which
the Classloder may report as a ClassNotFoundError.

Ensure that there exists a X Server and you have the permissions to
connect to the X server. Set the DISPLAY environment variable.

I don't have X11 server installed

Do I have to install X11? Even if my program is executed in the
Apache webserver ?
This error with awt/motif/MToolkit can be originated by mistake
above ?

Thanks for your help

try passing the following switch with the JRE:

-Djava.awt.headless=true

as in

java -Djava.awt.headless=true package.MyMainProgram

If there is an X-server some where nearby, you can point your
DISPLAY variable at it. Since I presume you aren't actually displaying anything
the humnan sitting at that X-Server wont notice anything. You may need to do an
'xhost +<...>' on the X-Server in order to get access.

Since you're running 1.3 the -Djava.awt.headless=true option isn't
available.

You might also look at Xvfb which is a headless X-Server for just
such emergencies
