"rainbow colors" problem in reading JPEG's

Question

Hi!
I am having a problems when trying to read jpeg-images.
This works:
            FileInputStream stream = new FileInputStream(imageFile);
            JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder(stream);
            BufferedImage image = decoder.decodeAsBufferedImage();But I need to use this approach, which sometimes produces strange colors:
        javax.imageio.ImageReader reader = getReader("jpeg");
        reader.setInput(ImageIO.createImageInputStream(inputStream), true, true);
        ImageReadParam param = reader.getDefaultReadParam();
        BufferedImage image = reader.read(0, param);The problem is that colors in some images read look like rainbow colors. I found that images saved by Photoshop are ok, but other images (straight from cameras or edited edited with Nikon viewer) are not.
I think that this issue might be related to color model, but I do not know what to do. I really would like to get some help, even minor suggestions are wellcome.

This is windows specific. You can't do windows specific stuff using Java unless you use some native library.
My suggestion: forget about my documents and use your own directory. Most applications use a directory such as '.APPNAME'. For example netbeans uses a directory '.netbeans' . That way your app is cross platform.
