NoClassDefFoundError in running Applets

[ashgonline]

Hi,
I am using Jcharts for generating charts from Excel worksheets.My problem is that while running program using applets I get following error:
java.lang.NoClassDefFoundError: org/jCharts/properties/ChartTypeProperties
at JCTest27.init(JCTest27.java:36)
at sun.applet.AppletPanel.run(AppletPanel.java:347)
at java.lang.Thread.run(Thread.java:536)

File is compiling without errors ,and further more there is no problem if I use frames .Then program is runnig Ok.
What could be the cause,Please help me.

here is the source code for the problem as I listed before for NoClassDefFoundError:
