Hello:
Wanted to try and install your application but got the following DOS prompt:

Did you include jcommon-0.7.1.jar on the classpath?

Regards,

I'm having the same issue, and almost the same error.

Exception in thread "main" java.lang.NoClassDefFoundError: com/jrefinery/ui/Drawable


I use the command;

java -classpath /export/home/tnordloh/jfreechart-0.9.4/lib/jcommon-0.7.1.jar:jfreechart-0.9.4.jar:jfreechart-0.9.4-demo.jar com.jrefinery.chart.demo.JFreeChartDemo

which I'm running while in the directory

/export/home/tnordloh/jfreechart-0.9.4


Any clue as to what I'm doing wrong?

I found the solution; I placed the jcommon jar file in Java's ext directory (where it belongs anyway) and the program began to work.

Evidently there was some portion of the -classpath that I'm not understanding.
