This might work (but without FileDialog):

import com.sun.image.codec.jpeg.*;

...

    OutputStream out = your output stream;

    Image img = your image;

try {

     // create a BufferedImage

     int w = (int)img.getWidth(null);
     int h = (int)img.getHeight(null);

     BufferedImage buffImg = new BufferedImage(w,h, 
BufferedImage.TYPE_INT_RGB);
     Graphics g = buffImg.createGraphics();

     g.drawImage(img, 0, 0, null);
     g.dispose();

     // save it

     JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
     encoder.encode(buffImg);
     out.close();
}
catch (Exception ex) {
}
