On the Win platform, the setFilenameFilter/accept method don't work. We must
use
the setFile method instead to set a filter.

A snippet from my JAVA How-to at
http://www.geocities.com/SiliconValley/Vista/1337

import java.awt.*;
public class UseFileDialog {

  public String loadFile(Frame f, String title, String defDir, String
fileType) {
    FileDialog fd = new FileDialog(f, title, FileDialog.LOAD);
    fd.setFile(fileType);
    fd.setDirectory(defDir);
    fd.setLocation(50, 50);
    fd.show();
    return fd.getFile();
    }

  public String saveFile(Frame f, String title, String defDir, String
fileType) {
    FileDialog fd = new FileDialog(f, title,    FileDialog.SAVE);
    fd.setFile(fileType);
    fd.setDirectory(defDir);
    fd.setLocation(50, 50);
    fd.show();
    return fd.getFile();
    }

  public static void main(String s[]) {
    UseFileDialog ufd = new UseFileDialog();
    System.out.println
      ("Loading : " + ufd.loadFile(new Frame(), "Open...", ".\\",
"*.java"));
    System.out.println
      ("Saving : " + ufd.saveFile(new Frame(), "Save...", ".\\", "*.java"));

    System.exit(0);
    }
}
