JPEG to Clipboard

Question

One of my tasks is to handle a "screenshot" like function in our app. We want to be able to copy our image and paste it into another app, like Photoshop, so the clipboard needs to be a system clipboard, and the format needs to be universal. I think we should be going for JPEGs, as they allow lots of colors and the code can be cross platform.
I am using a PixelGrabber to grab the pixels, handing those pixels off to a Toolbox.createImage method (which creates a Java Image), converting the Image to a BufferedImage, then using JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(aFileOutputStream) to encode the bufferedimage as a JPEG.
So far, this works okay. I can write the JPEG to t file and view it with another app. My problem comes with placing the image on the clipboard. I have tried to create a class for this:
class TransferableJPEG extends ByteArrayOutputStream implements Transferable{
     // converts Image into TransferableJPEG
Though I don't get any errors, I don't seem to be getting anything into the clipboard.
TransferableJPEG image = cif.createTransferableJPEG(pixels, width, height);
try {
     clipboard.setContents(image,this);
Anyone tried something like this? Am I wrong about the clipboard's requirement that all data to copy/paste must contained in a object that extends Transferable? If that is the case, how can I paste just the data portion of my JPEG, without any of the Object's wrappings?
ps. I am using a Maintosh for this, if that matters.
