Can check the code for me??

Question

import java.io.*;
import java.awt.*;
import javax.swing.*;
import javax.swing.filechooser.*;
import java.applet.*;
public class Mplayer extends Applet
     JButton openButton;
     JButton cancelButton;
     JFileChooser fc;
     int returnVal;
     public void init()
          fc = new JFileChooser();
          returnVal = fc.showOpenDialog(this);
     public void start()
          if(returnVal == JFileChooser.APPROVE_OPTION)
               File file = fc.getSelectedFile();
               String path = file.getPath();
               System.out.println("Opening: " +file.getPath());
          else
               System.out.println("Cancelled by user");
-- this code can be compiled, but when i open this applet, the 1st error is about java.security.AccessControlException, i think got some problem about " returnVal = fc.showOpenDialog(this);".. can help me to figure out..?? --
