[vtkusers] Exception java.lang.UnsatisfiedLinkError

[Lars Matthäus]

> Any idea of what to do???

The usual stuff:

a) Add vtk library directory (with .dll / .so files) to PATH
b) Add vtk.jar to your project
c) load the vtk libraries at start of the java-program, e.g.:

public class Test {

	static {
		try {
			System.loadLibrary("vtkHybridJava");
		} catch (final Throwable e) {
			System.out.println("cannot load vtkHybridJava, skipping...");
		}
		try {
			System.loadLibrary("vtkWidgetsJava");
		} catch (final Throwable e) {
			System.out.println("cannot load vtkWidgetsJava, skipping...");
		}
		try {
			System.loadLibrary("vtkVolumeRenderingJava");
		} catch (final Throwable e) {
			System.out.println("cannot load vtkVolumeRendering, skipping...");
		}
		try {
			System.loadLibrary("vtkParallelJava");
		} catch (final Throwable e) {
			System.out.println("cannot load vtkParallel, skipping...");
		}
	}

	public static void main(final String[] argv) {
		...
	}

}
