In my project I want to display watermark image using servlet..
code written by me as below...
please tell me what is wrong it shows output as orignal image... & i want it to be a watermark..

package com.solversa;

import java.awt.AlphaComposite;
import java.awt.Composite;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.net.URL;
import javax.imageio.ImageIO;
import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class kk extends HttpServlet

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException,IOException

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException,IOException

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));


// remember to define your content type of your response

// 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
catch(Exception e){}
