[vtkusers] java.lang.UnsatisfiedLinkError: VTKInit

[Matthew O'Brien]

Try putting this line in before you create your new vtkSphereSource.

static{System.loadLibrary("vtkJava");}

In order to get the java libraries pulled in, you have to have this line in
your code. vtkPanel has this line in it. When you create a new vtkPanel
before the sphere source, it gets the libraries. Without this line, it can't
find what it needs.

Hope this helps.

-----Original Message-----
I am attempting to use vtkSphereSource in Java. I have found that I
am forced to creat a vtkPanel object before vtkSphereSource will
work.

This code works fine:

  vtkPanel renPanel = new vtkPanel();
  vtkSphereSource sphere = new vtkSphereSource();

But this code:

  vtkSphereSource sphere = new vtkSphereSource();
  vtkPanel renPanel = new vtkPanel();

gives the following run time error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: VTKInit
        at vtk.vtkSphereSource.VTKInit(Native Method)
        at vtk.vtkObject.<init>(vtkObject.java:97)
        at vtk.vtkProcessObject.<init>(vtkProcessObject.java:78)
        at vtk.vtkSource.<init>(vtkSource.java:82)
        at vtk.vtkPolyDataSource.<init>(vtkPolyDataSource.java:30)
        at vtk.vtkSphereSource.<init>(vtkSphereSource.java:86)
        at SphFuncGlyph.<init>(SphFuncGlyph.java:28)

[ Line 28 of SphFuncGlyph.java is the line vtkSphereSource sphere
= new vtkSphereSource(); ]

Why does the vtkPanel matter? How can I create vtk objects
without having to make a vtkPanel?

Thanks,


Phil Cook
