This could be because of the version of compiler and jvm is not same.

If your package's directory structure is like c:->test->javaprep, then the class path should be only upto test. Don't include javaprep. In your case the classpath should have only c:\. Classpath should always mention the parent direcroty of the package directory. But, still the runtime error looks strange. It should acuatlly be . Anyways, try this.
