[vtkusers] java.lang.UnsatisfiedLinkError: VTKInit ... again

[Bernard Giroux]

Do you instatiate the vtkStructuredGrid before the vtkPanel?  If yes,  
this is the problem: the vtk libraries are loaded by the vtkPanel  
object (look in vtkPanel.java for the following lines...)


   static {
     System.loadLibrary("vtkCommonJava");
     System.loadLibrary("vtkFilteringJava");
     System.loadLibrary("vtkIOJava");
     System.loadLibrary("vtkImagingJava");
     System.loadLibrary("vtkGraphicsJava");
     System.loadLibrary("vtkRenderingJava");
     try {
       System.loadLibrary("vtkHybridJava");
     } catch (Throwable e) {
       System.out.println("cannot load vtkHybrid, skipping...");
     }
     try {
       System.loadLibrary("vtkVolumeRenderingJava");
     } catch (Throwable e) {
       System.out.println("cannot load vtkVolumeRendering,  
skipping...");
     }
   }
