CFCHART not working - Windows + MX 6.1

I cannot get cfchart to work under MX 6.1. The simplest example throws an exception.

The chart could not be generated due to an error in the graphing engine.
-java.lang.NoClassDefFoundError
at com.gp.webcharts3D.model.ExAxisStyle.<init>(ExAxisStyle.java)
at com.gp.webcharts3D.model.ExChartStyle.<init>(ExChartStyle.java)

For kicks I tried http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_19605

Added to jvm arguments:
-Xbootclasspath/a:C:\\CFusionMX\\lib\\webchartsJava2D.jar -Djava.awt.graphicsenv=com.gp.java2d.ExHeadlessGraphicsEnvironment

It still throws an exception:

The chart could not be generated due to an error in the graphing engine.

Anyone else had this problem or know how to fix it?
