What do you have in your classpath? Is it com/storekraft/lib (wrong) or the directory that com/storekraft/lib is in (right)? Is the driver file you have there a compiled class file (right), or a Java source file (wrong)? Have you made any spelling errors anywhere? (Oh, that would be wrong too.
)
You're right though, even if a package just contains a single class, you can import it with:
import com.storekraft.lib.*;
