Image generation - missing jar file???

I'm following the instructions for image generation as descirbed here:-

http://www.chemaxon.com/marvin/examples/beans/image-generation/index.html

I have copied jar files into almost every lib directory under my tomcat installation but I still can't get the images to display.

The error message in catalina.out is below - i don't think the IP address that is shown is the address of the machine on which I'm running tomcat - what should I do?

Kind regards

The problem is that there is no graphical interface when Java running.

Please see the linking topic.

generate image without opening a display

It describes what you have to do in this case.

 

Many thanks, I didn't think the link you sent really explained what to do but an internet search gave me the answer I needed.

Just set the CATALINA_OPTS environment variable to include -Djava.awt.headless=true and restart tomcat - the images display.

Kind regards

Sorry, if I was not clear.

I wanted to point on that the java.awt.headless JVM parameter is the clue.

By the way, there is alternative solution (virtual X11 server) is also mentioned in that topic.

Anyway, I am glad that your problem has been solved.
