I m new to Netbeans and when i created a simple midlet named Login and src code is as follows..

import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

/**
* @author veeru
*/
public class Login extends MIDlet implements CommandListener {
private Display display;
private Form form;
private TextField uname, pwd;
private Command login, Exit,Forgot,signup;
public boolean log = false;
private Alert alertSuccess;
private Alert alertFailure;

public Login(){
uname = new TextField("UserName ","",15,TextField.ANY);
pwd = new TextField("Password ","",10,TextField.ANY);
//image = new TextField("Image :","",20,TextField.ANY);
form = new Form("LOGIN PAGE");
Exit = new Command("Exit", Command.CANCEL, 2);
login = new Command("Login", Command.OK, 2);
signup = new Command("NewUser Signup", Command.OK, 2);
Forgot = new Command("Forgot UserName/Password", Command.OK, 2);
}

public void startApp() {
display = Display.getDisplay(this);
form.append(uname);
form.append(pwd);
form.addCommand(Forgot);
form.addCommand(signup);
//form.append(image);
form.addCommand(login);
form.addCommand(Exit);
form.setCommandListener(this);
display.setCurrent(form);
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
}

public void commandAction(Command c, Displayable d) {
throw new UnsupportedOperationException("Not supported yet.");
}
