I am trying to encode (write) jpeg 2000 in Java. I am reading a '.bmp' image and try to write '.jp2' image. I am using: 

javax.imageio.ImageIO.write(img1, "jpeg 2000", file1);

I do not receive any error, but the size of the produced image is zero. Can anybody help me please?

Thanks a lot in advance.

    Please provide more information. What is img1? Is it valid? What is file1? Is it valid? ... – InsertNickHere Sep 21 '10 at 18:34
  • img1 is a BufferedImage, file1 is declared as: new File("E/a.jp2"); they are valid, because if I try to write the image as a 'bmp', 'jpg' or 'png' file, everything is fine. – Shadi Sep 21 '10 at 18:37

The only problem was that when I was installing JAI_ImageIO, I should have selected "custome installation" and checked everything to be installed. Thanks everyone.
