Jfree chart implementation question

Hello.
I downloaded jfree charts and trying to use them.
Wrote a simple bar chart program. Unable to run it due to some missing jar files.
Can anyone tell me the jar file required for these 2 import statements
and also the location where i can find it.

import org.jfree.ui.ApplicationFrame;
import org.jfree.ui.RefineryUtilities;

Thanks.

works absolutely!
Why was it not taking my classpath before?

could it be because of the space in "My Documents" ?

because the -cp option overrides the classpath env var.
