[Desarrollo e Investigación <de...@catenaria.cl>]

	I've been worked with Servlet and i tried to generate a JPG image but 
Tomcat Displays this error:

java.lang.InternalError: Can't connect to X11 window server using ':0' as the 
value of the DISPLAY variable. at 
sun.awt.X11GraphicsEnvironment.initDisplay(Native Method) at 
sun.awt.X11GraphicsEnvironment.(X11GraphicsEnvironment.java:126) 

I use the Tomcat 4.0.4-b3, Java 1.4.0, Linux Red Hat 7.2

Because you are using JDK 1.4, please try:
   -Djava.awt.headless=true
option in your start-up script.
For details, please read:
