But you haven't got the path set correctly, or there would be no
error.  You need to do first locate the directory containing all the
VTK DLLs; suppose it is C:\vtk.  Then you need to do one of two things; either:

(1) set the PATH variable (LD_LIBRARY_PATH on unix) to contain C:\vtk; or
(2) supply -Djava.library.path=C:\vtk argument on the java command line

You're misinterpreting this output.  It simply is telling you what
source line the error occurred at and the source *.java files happened
to be built from C:/martink/...
