problem running JDK

I seem to have trouble running my classes. I compile a class, but when I run it, I get error message: "java.lang.NoClassDefFoundError". I get this error even with classes that I know for sure worked before. All of the sudden I started to get this message. What's wrong here?

Possible causes of your problem.
1) you might have changed your classpath.
2) if you declare package statement in your class coding, you need to invoke with qualified class name (full package name + class name).
3) do not put ".class" when you run with Java.exe command.
Hope it helps.

I agree. Here's the link:
