JOGL and Large Background Images

Question

Hullo gurus! :)
I'm having trouble with converting my work-in-progress RTS-style game from using Graphics2D into a (hopefully) faster JOGL format.
In my current approach, I've got a 2000x2000 pixel JPG which contains the entire map. Units and structures are layered on top of the background image, and nature takes its course.
Now, I'm trying to figure JOGL out, and have picked up a book and read a number of samples within, as well as around the web. One of the examples from this very site suggested a process of converting the image into a format that would display as expected on the screen. The code snippet looks something like this:
        Image i = Toolkit.getDefaultToolkit().createImage ("Map_0_0.jpg");
        MediaTracker tracker = new MediaTracker(new Canvas());
        tracker.addImage (i, 0);
        try {
            tracker.waitForAll();
        } catch (InterruptedException ie) {}
        dukeHeight = i.getHeight(null);
        dukeWidth = i.getWidth(null);
        System.out.println ("Got image, width=" +
                            dukeWidth + ", height=" + dukeHeight);
        // turn it into a BufferedImage
        WritableRaster raster =
            Raster.createInterleavedRaster (DataBuffer.TYPE_BYTE,
                                            dukeWidth,
                                            dukeHeight,
                                            4,
                                            null);
        ComponentColorModel colorModel=
            new ComponentColorModel (ColorSpace.getInstance(ColorSpace.CS_sRGB),
                                     new int[] {8,8,8,8},
                                     true,
                                     false,
                                     ComponentColorModel.TRANSLUCENT,
                                     DataBuffer.TYPE_BYTE);
        BufferedImage dukeImg =
            new BufferedImage (colorModel, // color model
                               raster,
                               false, // isRasterPremultiplied
                               null); // properties
        Graphics2D g = dukeImg.createGraphics();
        // use an AffineTransformation to draw upside-down in the java
        // sense, which will make it right-side-up in OpenGL
        AffineTransform gt = new AffineTransform();
        gt.translate (0, dukeHeight);
        gt.scale (1, -1d);
        g.transform (gt);
        g.drawImage (i, null, null);
        // now retrieve the underlying byte array from dukeImg
        DataBufferByte dukeBuf = (DataBufferByte)raster.getDataBuffer();
        dukeRGBA = dukeBuf.getData();       
        g.dispose();However, on the "g.drawImage (i, null, null);" line, I get the "Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space.
Am I doing something dumb? Is there a better approach that will let me render everything the way I'm trying to? Any advice would be greatly appreciated... :)

This is wrong, wrong, wrong. Please read the F1 Help for how
to properly
create child pages from your templates.
All links in the TEMPLATE file should be one of three kinds -
1. Relative to the template file, e.g.,
<a href="../ (meaning that you must go up one level from
the template folder
to reach the root of the site, hence all other files, since
none of them
should be in the templates folder)
2. Relative to the site root, e.g.,
<a href="/ (meaning that one would begin looking for the
linked file at the
root of the site and follow the pathing from that point)
3. Absolute, e.g.,
<a href="
http:// (meaning that the link is to a page
external to the site).
