There is no need to add vtkPanel.java or vtkCanvas.java, vtkPanel.class and vtkCanvas.class should be within the vtk.jar in subdirectory vtk. You may check it by opening vtk.jar with WinZip or similar program, or by
typing 
  jar tf c:\vtk42\bin\vtk.jar | more

The error you are reporting may happen when class name does not much a file  in which it is defined. Say you defines a class vtkPanel but saved it in file SomethingElse.java. 
Did you modify any of the example you are compiling?
Created new file from vtkPanel?
