import java.awt.Composite;

URL url2 = new URL("http://weblogs.java.net/jag/Image54-large.jpeg");
BufferedImage im2 = ImageIO.read(url2);
Graphics g = im2.getGraphics();
Graphics2D g2d = (Graphics2D)g;
Composite originalComposite = g2d.getComposite();
g2d.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.1f));
try

g2d.drawImage(im2,50,50,null);
g2d.dispose();
// remember to define your content type of your response
response.setContentType("image/jpeg");
// grab the servlet outputstream
ServletOutputStream out = response.getOutputStream();
// write your combined imaged to the response output stream
ImageIO.write( im2, "jpeg", out );
//display and close output stream
out.flush();
out.close();
