System is missing some classes from JBuilder. It is not enough to include
only a jar file with your application, but also the classes from all jar
files you have added to your project.

That's most likely the correct classpath.

It can be that it missises some other classes. Try running java.exe instead
of javaw.exe, it will open console and most likely it will write some error
messages there.
