Question

Hi every one, I am new to JSP I have a code in JAVA which is used to generate an image from a temporary file of size 34.1MB.
I am unable to convert that JAVA code into JSP,can anyone help me in this regard
Here is my code
import java.awt.image.*;
import java.io.*;
import java.util.*;
import javax.imageio.*;
import javax.swing.*;
public class ExampleCreate {
    public static void main(String[] args) throws Exception {
        final int H = 2530;
        final int W = 3630;
        int[] pixels = createPixels(W*H);
        BufferedImage image = toImage(pixels, W, H);
        display(image);
        ImageIO.write(image, "jpg", new File("static.jpg"));
  static int[] createPixels(int size) throws Exception{
       int[] pixels = new int[size];
       int[] colors = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,102,104,106,108,110,112,114,116,118,120,122,124,126,0xff0000,0x00ff00,0x0000ff,0x00000f,0xfff000,0xff00ff,0xffffff,0xf00000};
       FileReader fr = new FileReader("SST.tmp");
       BufferedReader br = new BufferedReader(fr);
       String text = br.readLine();
       int c = 0;
       for(int i = 0; i < size; ++ i){
                 text = br.readLine();
                 c = Integer.parseInt(text);
                 if(c < 0)
                      c = 0;
                 pixels[i] = colors[c];
       br.close();
   return pixels;
    static BufferedImage toImage(int[] pixels, int w, int h) {
        DataBuffer db = new DataBufferInt(pixels, w*h);
        WritableRaster raster = Raster.createPackedRaster(db,
            w, h, w, new int[] {0xff0000, 0xff00, 0xff}, null);
        ColorModel cm = new DirectColorModel(24, 0xff0000, 0xff00, 0xff);
        return new BufferedImage(cm, raster, false, null);
    static void display(BufferedImage image) {
        final JFrame f = new JFrame("");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(new JLabel(new ImageIcon(image)));
        f.pack();
        SwingUtilities.invokeLater(new Runnable(){
            public void run() {
                f.setLocationRelativeTo(null);
                f.setVisible(true);
}thanks&regards

According to me just convert ths code to servlet and instead of displaying the image with BufferedImage just stream it (the image) to the browser. This will be useful to catch the general idea.
