May be you should use ImageIO.write(..., "bmp", ...)? I say about ImageIO because you made an accent on BMP. So, you need a BMP bitmap data with BMP header.

Create BufferedImage (http://download.oracle.com/javase/1.4.2/docs/api/java/awt/image/BufferedImage.html) with required parameter and serialize it to BMP.

...
Robot robot = new Robot();
Rectangle screenRectangle = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
BufferedImage image = robot.createScreenCapture(screenRectangle);
ByteArrayOutputStream out = new ByteArrayOutputStream();
ImageIO.write(image, "bmp", out);
...
