[vtk-developers] Exception in thread "main" java.lang.UnsatisfiedLinkError: no vtkCommonJava in java.library.path

[Robert Häckl]

I guess we come nearer to the solution :-)
First of all I looked here how to load libraries:
http://www.vtk.org/Wiki/VTK/Java_Wrapping

The snipped I added to my main was:

if  (!vtkNativeLibrary.LoadAllNativeLibraries())  {
             for  (vtkNativeLibrary lib:  vtkNativeLibrary.values())  {
                 if  (!lib.IsLoaded())  {
                     System.out.println(lib.GetLibraryName()  +  " not loaded");
                 }
             }
         }
         vtkNativeLibrary.DisableOutputWindow(null);



And then i got those printings on my console:

vtkCommonJava not loaded
vtkFilteringJava not loaded
vtkGeovisJava not loaded
vtkGraphicsJava not loaded
vtkHybridJava not loaded
vtkImagingJava not loaded
vtkInfovisJava not loaded
vtkIOJava not loaded
vtkRenderingJava not loaded
vtkViewsJava not loaded
vtkVolumeRenderingJava not loaded
vtkWidgetsJava not loaded
vtkChartsJava not loaded

So I know that the libraries are not loaded. This is a complete step 
further, but what I now need to know is, how to load the libraries.
