Re: Can't connect to X11 window server using '0:0' as the value of
the display
Try running the Tomcat VM with the -Djava.awt.headless=true system
property (set it in an environment variable named CATALINA_OPTS).

Thanks,
I put System.setProperty("java.awt.headless", "true");
in my servlet init method and it's ok now.

Depends what you want to do basically. Running headless causes the JVM to
replace most of the basic functions that you previously needed to be
provided by the standard Linux utility Xvfb (e.g. fonts, color-mappings).
I can think of cases where headless isn't enough, but if you are that
creative, it deserves another topic ;-)

Hi,
does it need modifications in the application or it will work with every AWT
dependent application?
