Answer :
You have correcly find out what is wrong : by default, you need a XServer to use
jcaptcha. the java Toolkit use it to build images.
The captcha team (in fact mathieu) had a thought about this and designed a

it It provides a way to avoid the installation of a xserver. This trick is documented
in the javadoc.
