Can anyone tell me why the following simple applet produces a
com.ms.security.SecurityException...  every time it is brought up?


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

public class Test extends Applet {

    public void init() {
        try {
            FileOutputStream out = new FileOutputStream( "testing.dat" );
            ObjectOutputStream oos = new ObjectOutputStream( out );
            oos.writeObject( "testing" );
            oos.flush();
            oos.close();
            FileInputStream in = new FileInputStream( "testing.dat" );
            ObjectInputStream inStream = new ObjectInputStream( in );
            String t = (String) inStream.readObject();
            inStream.close();
            Panel p = new Panel();
            p.add( new Label( t ) );
            add( "Center", p );
            setSize( 400, 100 );
            setVisible( true );
         }
        catch (Exception e) {
            System.err.println(e);
            System.exit(1);
        }
    }

}
