Applet data to TextFile

Hai
  I am having an Applet.

import java.awt.*;
import java.io.*;
import java.applet.*;

public class FileTest extends Applet {

  public void paint(Graphics g) {
    String fileName = "MyTest.txt";
    try {
      FileOutputStream fos = new FileOutputStream(fileName);
      PrintStream outputFile = new PrintStream(fos);
      outputFile.println(" This is a test");
      outputFile.close();
      fos.close();
      g.drawString("The applet created the file " + fileName, 10, 20);
    }
    catch (Exception e) {
      g.drawString(e + "", 10, 20);
    }
  } // paint

}


If I execute this It shows error: access denied  java.FilePermission .....

you need to sign your applet

And you shouldn't do the file writing in paint, this will get called every time the applet requires repainting.

I read that article.

I did the Signed Applet using JDK Plugin

It is working in my system. ( It is creating the txt file in desktop not in the same folder where the class file resides ) and also When I tried from another system this is not working....

When I try Signed Applet in Internet Explorer
makecert is not accepted by the command line

Can you help me in doing this....

You need to write a server component (such as a servlet) to accept the data and write the file to server.
