I can't open the ChartApplet.class file because it's a third-party sourced applet.
I suspect though that the problem is that the code on the site isn't looking for a Jar file, it's looking for the class files. The class files have been deleted to force use of the Jar file but it doesn't look for that and gives the error. Do you think that's possible?
Thanks for your help here I really appreciate it.
