Applet - Create image problem

Question

I have an applet that draws scribble and send to Server. Server save the image drawn in applet.
Server side I have no problem. How much bytes are available in client side, same as I get in server side. So i have no doubt in server side code.
When I drawn simple 2 or three lines, then The image is looking ok.
But when i try to draw scribbling more, then the image is corrupted.
I dont know where am doing wrong.
Applet code :
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.net.*;
import javax.imageio.*;
public class Scribble_Send extends Applet {
    private int last_x = 0;
    private int last_y = 0;
    private Color current_color = Color.black;
    private Button clear_button;
    BufferedImage bi =new BufferedImage(400,280,BufferedImage.TYPE_INT_RGB);
    Graphics2D g2 = (Graphics2D)bi.createGraphics();
    public void init() {
         this.setBackground(Color.lightGray);
         Button b = new Button("save");
         b.addActionListener(new ActionListener() {
       public void actionPerformed(ActionEvent ae) {
          showStatus("button pressed");
           try {
                ByteArrayOutputStream baos = new ByteArrayOutputStream();
          ImageIO.write(bi,"JPEG",baos);
          byte[] buf = baos.toByteArray();
                showStatus("buf length"+buf.length);
                URL servletURL = new URL(getCodeBase(),"/servlet/Write_Scribble");
              URLConnection servletConnection = servletURL.openConnection();
          servletConnection.setDoOutput(true);
          servletConnection.setUseCaches(false);
                OutputStream os = servletConnection.getOutputStream();
                os.write(buf);
             }catch (Exception e) {
             showStatus(e.toString());
      add(b);
    public boolean mouseDown(Event e, int x, int y)
        last_x = x; last_y = y;
        return true;
    public boolean mouseDrag(Event e, int x, int y)
        Graphics g = this.getGraphics();
        g.setColor(current_color);
        g.drawLine(last_x, last_y, x, y);
        g2.setColor(Color.white);
        g2.drawLine(last_x, last_y, x, y);
        last_x = x;
        last_y = y;
        return true;
}And Server Side:
public class Write_Scribble extends HttpServlet {
     public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
       Writer writer = null;
      try{
          InputStream in = req.getInputStream();
            ServletContext servletContext = getServletContext();
            String file = servletContext.getRealPath("/hello.jpg");
            int count, offset = 0;
          byte[] buff = new byte[65536];
            FileOutputStream fis = new FileOutputStream(file);
            while ((count = in.read(buff)) > 0)
                 fis.write(buff,offset,count);
               offset += count;
          fis.flush();
          fis.close();
      catch (Exception e)
            log("Exception"+e);
          e.printStackTrace();
}  Help me regarding creating an Image in memory.
Thanks
