[vtkusers] converting java array to vtkimage data

[Sebastien Jourdain]

Hi Nikhil,

You forgot to load the system library.

You have to add the following line in your code as well as having depending
on your system the directory that content the vtk library inside the
environment vairiable PATH/LD_LIBRARY_PATH/DYLD_LIBRARY_PATH (win/unix/mac).

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...");
    }
  }
