InternalError (Bug?)

Dears,

back again for a problem of mine. This time, however, I have the feeling to 
have discovered a bug.

I'm using batik to convert svg files to bitmap on the fly in a tomcat 
application. The tomcat application is supposed to run in a server under an 
environment which is detached from any X11 server eventually running.

When I try my tomcat app from the debugger I use, which starts tomcat in the 
same session of the debbugger graphical console, everything works fine.

Deploying the app to the final server, I get the exception you can see at the 
end of this message.

The matter is that batik tries to access an GraphicsEnvironment which is 
unexistant in a detached server environment.

Question: Am I completely wrong when I assume that batik is supposed to run on 
services?

Regards,

	Giampaolo Tomassoni

It works, Jorg. Didn't know of a headless setting in awt...

Thank very much,

You need to run your java app in headless mode. For tomcat this means 
you should export env variable CATALINA_OPTS=-Djava.awt.headless=true
and restart the container.
