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 .....
How to send the output to txt file from Applet?

I want to save the Applet and Txt file in server and  clients want to write the information to the txt file through the Applet.
Is it possible ? If so How?

Thanks
