This code should work

vtkPanel panel = new vtkPanel();
vtk3DSImporter importer = new vtk3DSImporter();

Yes, I'm using VTK a lot in Java apps. And regarding the deployment, I  
agree that it can be tricky...
Could you be more precise on what you expect to do ? (Web deploy with  
JWS or Pre-compiled binary pack specific to an architecture)

I've managed to make the JWS works once, but it was some times ago  
(vtk 4.2). I haven't tried yet.
I can explain the procedure to make a JavaWebStart package of VTK with  
automatic system detection used to download the proper native code.
