Forming an image from a ByteBuffer

Question

I would be grateful if anybody could help me with a problem i am having with my program, i am trying to read pixels to form an image, i have the whole thing working now, however it is grayscale, and i cant work out why. Any help would be appreciated.
     GL11.glReadBuffer(GL11.GL_FRONT);
            ByteBuffer pixels = ByteBuffer.allocateDirect(400*400*3);
            GL11.glReadPixels(0, 0, 400, 400, GL11.GL_RGB, GL11.GL_UNSIGNED_BYTE, pixels);
            ColorModel glColorModel = new ComponentColorModel(ColorSpace.getInstance(ColorSpace.CS_sRGB),
                                            new int[] {8,8,8,0},
                                            false,
                                            false,
                                            ComponentColorModel.OPAQUE,
                                            DataBuffer.TYPE_BYTE);
            int[] band = new int[3];
            // make array from byteBuffer to make a DataBufferByte from array...
            byte [] byteA=new byte[400*400*3];
            pixels.get(byteA);
            DataBuffer db = new DataBufferByte(byteA, 400*400*3, 0);
            WritableRaster raster = Raster.createInterleavedRaster(db, 400, 400, 400*3, 3, band, null);
            // make my image
            BufferedImage image = new BufferedImage(glColorModel, raster, false, null);//new java.util.Hashtable());thanks

Answer 1

Ok, investigation further:
            for (int i = 0; i < 1600 ; i ++){
                System.out.println(byteA);
}produces non grayscale numbers, such as 76 51 25 76 51 25 76 51 25 , ie the background. This means the problem is in the raster part, maybe the glColorModel? the thing is i just coppied the glColorModel straight from my texture loading thing, and they are in colour....
