java.lang.ClassNotFoundExceptionthrown oncom.ms.*package when applet runs
SymptomsWhen running an applet in a browser using the Sun JRE, a
ClassNotFoundExceptionis thrown by theClassLoaderon thecom.ms.*package. The same applet runs under the Microsoft VM.Cause
The Microsoft VM provides many proprietary class libraries, including J/Direct, AFC, and WFC. These package are not available in the Sun JRE, so a
ClassNotFoundExceptionis thrown when the applet runs.Resolution
The workaround is to migrate the applet source code from using the Microsoft proprietary class libraries to similar classes in the Java 2 platform.
