having problems running the very first demo JfreechartDemo

[Brinda]

Just downloaded jfreechart-0.9.2.zip from the sourceforge website. Unpacked it and tried to run the jFreechartDemo. I got an exception "

Exception in thread "main" java.lang.NoClassDefFoundError: source/com/jrefinery/
chart/demo/jFreeChartDemo

What is it that I am doing wrong ??

I tried to compile the files and then run the demo, I got 100 errors when I tried to compile.

What could possibly be wrong ??

Could someone please tell me what is going on ??

I am new to this and need some help

Thanks.

Class names are case sensitive, so 'jFreeChartDemo' is not the same as 'JFreeChartDemo'.
