full source code is wrong,

I downloaded the zip from the link above<required JFreeChart library jar files>. That does not work. You need additionally jfreechart-1.0.6.jar, itext-2.0.5.jar (manifest refers to itext-1.4.8.jar but I could not locate it) also in the class path. And I had to remove the lib/jfreechart-1.0.4-experimental.jar from the class path.
The jar itself would not work but after unjar'ing the jfreechart-1.0.4-demo and setting the classpath as above I got it to work.
