Hi, I'm trying to write a desktop application from the scratch by
using NetBeans IDE 6.1. I already created 2 files, which are main.java
and login.java. What I need is : when I run the application, the login
form which is called in login.java is directly launched. But I faced
errors in main.java. Please help me to fix it. Here are the codes :

---- main.java -----

package ecgterminal1;

import org.jdesktop.application.Application;
import org.jdesktop.application.SingleFrameApplication;

public class Main extends SingleFrameApplication {

@Override protected void startup() {
show(new login(this)); //ERROR : can't find symbol

Read the error message, what does it mean? what can it refer to?
compare what you have with what you are trying to use...

    }

    @Override protected void configureWindow(java.awt.Window root) {
    }

    public static Main getApplication() {
        return Application.getInstance(Main.class);
    }

    public static void main(String[] args) {
        launch(login.class, args); //ERROR : application can't be
applied to ....
    }

}

----- login.java -----

package ecgterminal1;

public class login extends javax.swing.JDialog {

    public login(java.awt.Frame parent, boolean modal) {
        super(parent, modal);
        initComponents();
    }

---- code generated by netbeans here -----

    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                login dialog = new login(new javax.swin=

g.JFrame(),

true);
                dialog.addWindowListener(new
java.awt.event.WindowAdapter() {
                    public void
windowClosing(java.awt.event.WindowEvent e) {
                        System.exit(0);
                    }
                });
                dialog.setVisible(true);
            }
        });
    }
