FileDialog problem

[VAX]

I have a problem for using FileDialog.

The code are as follows:
FileDialog fd = new FileDialog(new Frame(), "Open Testing File", FileDialog.l);
fd.show();
System.out.println(fd.getName());

The error message as:
java.lang.NullPointerException

Thank you.

import java.awt.*;
import java.awt.event.*;
import java.io.*;
class myframe extends Frame
{
public static void main(String[] args) throws Exception
{
myframe obj=new myframe();
obj.setLayout(new BorderLayout());
Button b=new Button("click");
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
FileDialog fd = new FileDialog(new Frame(), "Open Testing File", FileDialog.LOAD);
fd.show();
System.out.println(fd.getFile());
}
});
obj.add(b);
obj.setSize(200,200);
obj.setVisible(true);
