Hello ,

I need help urgently to present my final project of "How to generate real time image (on the fly)to WAP . I am beginner in java language also leaked of knowledged in java.

i used a sevlet tomcat 4.1 as a server and openwave 5.1 as a phone simulator. i have to display the real time image at the simulator but i donn't have any idea to do it.

This is my program to send image from sevlet to openwave:-

import java.io.*;

import java.util.*;

import javax.servlet.*;

import javax.servlet.http.*;

public class LApple extends HttpServlet {

public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
doPost( req, res );

}

public void doPost (HttpServletRequest req, HttpServletResponse res)

throws ServletException, IOException {

res.addHeader("Cache-Control","no-cache, must-

revalidate");

res.addHeader("Pragma","no-cache");

res.setContentType("text/vnd.wap.wml");

char ch ='"';

String ch2="'";

PrintWriter pw = res.getWriter();

pw.println(" ");

pw.println(" ");

pw.println("

");

pw.println("Apple for you!");

pw.println(" ");

pw.println(" ");

pw.println(" ");

pw.println(" ");

pw.println(" ");

pw.println("

"+new Date().toString()+"

pw.println("

hould be reloaded every 10 seconds from http://127.0.0.1.

pw.println("

pw.println(" ");

pw.println(" ");

}

}

Your program is helpful to convert image to wbmp format but i don't know how to use to get the display in my openwave simulator.

/ My friend try to continue by wrote this code but

don't know how to display output stream

public static void main(String[] args) throws Exception

{

WBmpRenderer wbmp = new WBmpRenderer((byte)50, (byte)50);

Graphics2D wbmpg2d = wbmp.graphicsContext();

Ellipse2D e = new Ellipse2D.Double(10,10,20,20);

wbmpg2d.setPaint(new Color(200, 200, 200));

wbmpg2d.fill(e);

wbmpg2d.draw(e);

}
}
