FileDialog in SAVE mode does not throw file access error

Question

Hi,
We are using FileDialog to SAVE and LOAD files.
If a file is selected to which the user has no access, then LOAD dialog throws an
error, but SAVE dialog does not.
Have I skipped something ??
Below is a sample code :
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TestClass extends JFrame {
public TestClass() {
setSize(400, 400);
JPanel l_objPanel = new JPanel();
getContentPane().add(l_objPanel);
final JButton l_objButton = new JButton("FileOpen");
l_objPanel.add(l_objButton);
l_objButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent p_objEvent) {
FileDialog l_objDlg = new FileDialog(TestClass.this, "Save now", FileDialog.SAVE);
l_objDlg.show();
public static void main( String[] strArgs ) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch(Exception e) {
e.printStackTrace();
TestClass l_objDlg = new TestClass();
l_objDlg.show();

The bug you pointed out is pretty different: JWS should work offline if no network connection is available, but no such behaviour is provided, never the less granted, if your server is down. No matter what your 'web-distributed' app is (ASP, SaaS, SOA, RIA, cloud, ...), you may have it work without a network, but no architectural pattern would ever remotely consider it should run if the providing server is down (and is not redirecting or, at least, sending some 'manageble' error).
