You are likely missing a class file that in your jar file.

I had a similar situation and found that the new "next-generation" java plugin does not report NoClassDefFoundError, but instead reports findAppletJDKLevel.

To see if you are missing class files, do the following:

1) Close all browsers, ensuring that there are no plugin coffee cup icons in the Windows taskbar.
2) Open the Java Control panel (Start->Control Panel->Java).
2.5) On the General tab, clear cache by clicking Settings..., Delete Files..., OK.
3) Open the Advanced tab.
4) Expand the Java Plug-in tree option.
5) Ensure that the "Enable the next-generation Java Plug-in" option is NOT checked and click OK.
6) Visit your page again.
7) View the java console stacktrace. It should include NoClassDefFoundError error message.
8) Add the missing classes to your jar file.
