Loading a raw image in BufferedImage

Question

Hi guys,
I'm very new to java .I have a raw image which has 32 bit pixels which has ABGR...with alpha as the most signficant byte and the red as the least significant byte. I have an array of ints and I want to load this to a BufferedImage object. I then use a JPanel and render the BufferedImage on to it. I tried doing with other file formats like jpg , gifs and so the rendering to the JPanel works fine. But I'm not able to get the array of ints to be stored in BufferedImage correctly. Could you please let me know what I did was wrong or any suggestions?
Currently I have a class called RGBAImage that reads the raw image and stores it as an array of ints.
So in order to create a BufferedImage I do this roughly,
DataBufferInt buffer = new DataBufferInt(img.getPixels() , img.getPixels().length) ;
//                                                        bits  red                   green                   blue                 alpha
ColorModel cm = new DirectColorModel(32, (int)0x000000ff , (int)0x0000ff00 , (int)0x00ff0000 , (int)0xff000000) ;
SampleModel sm = cm.createCompatibleSampleModel(img.getWidth , img.getHeight) ;
WriteableRaster raster = Raster.createWritableRaster(sm , buffer , null) ;
BufferedImage bimg = new BufferedImage(cm , raster , false , null) ;Is this how its to be done? I am not getting the image drawn on the panel. Any suggestions or links?
Thank you
Siddharth

I have an array of ints and I want to load this to a BufferedImage object.In your sample code I cannot see how the int array you are talking about becomes the image data. Also, what is the img variable? Please provide a more complete code sample.
