great!

Well, not exactly unportable. You just have to convert the output of  
the watershed to a more usable type (not tested):

import org.itk.io.*;
import org.itk.denoising.*;
import org.itk.filtering.*;
import org.itk.segmentationandthreshold.*;

public class WatershedSegmentation1
{
   public static void main( String argv[] )
   {
     System.out.println("WatershedSegmentation1 Example");

     itkImageFileReaderIF2 reader = new itkImageFileReaderIF2();
     reader.SetFileName( argv[0] );

     itkGradientAnisotropicDiffusionImageFilterIF2IF2 diffusion =
       new itkGradientAnisotropicDiffusionImageFilterIF2IF2();

     diffusion.SetInput( reader.GetOutput() );
     diffusion.SetTimeStep( 0.0625 );
     diffusion.SetConductanceParameter( 9.0 );
     diffusion.SetNumberOfIterations(  5 );

     itkGradientMagnitudeImageFilterIF2IF2 gradient =
       new itkGradientMagnitudeImageFilterIF2IF2();

     gradient.SetInput(diffusion.GetOutput());

     itkWatershedImageFilterIF2 watershed =
       new itkWatershedImageFilterIF2();

     watershed.SetInput( gradient.GetOutput() );
     watershed.SetThreshold( 0.01 );
     watershed.SetLevel( 0.2 );

     itkRelabelComponentImageFilterIUL2IUC2 relabel =
       new itkRelabelComponentImageFilterIUL2IUC2();
     relabel.SetInput( watershed.GetOutput() );

     itkImageFileWriterIUL2 writer = new itkImageFileWriterIUL2();
     writer.SetFileName( argv[1] );
     writer.SetInput( relabel.GetOutput()  );
     writer.Update();

   }

}

Can you be more specific on what is missing?
