You would do it in this way

Image img = ImageIO.read(new ByteArrayInputStream(imageBytes));
ImageIcon imgIcon = new ImageIcon(img);

JLabel label = new JLabel(imgIcon);

but the JPG2000 decoder isn't supplied with standard SDK, you should head here (Java Advanced Imaging) and use the right decoder for that format..
