Example workbench chat missing

Hello,
in the workbench example the chart is not showing.
The class could not be found.
What do I have to do?

Here is the error message from catalina.out

Re: Example workbench chat missing

Posted by Reinier Mostert <re...@clabo.co.za>.
Hi,

I added a parameter when starting the Java session for tomcat, because
on Linux (or Unix), the AWT classes are not normally available.

I edited tomcat4.conf, and added the option
-Djava.awt.headless=true
This option is not available on all versions of Java, it was added in
1.4.1, I think.

Hope this helps.
