AddCommand Help

Question

Hi Everybody,
Am writing a J2ME application which requires users to log into the application. A snippet of the code is mentioned here
public LoginScreen(midlet) {
super("Login");
this.midlet = midlet;
_user = new TextField("Code", "", 10, TextField.NUMERIC);
_pass = new TextField("Pass", "", 10, TextField.PASSWORD);
append(_user);
append(_pass);
addCommand(_login = new Command("Login",Command.SCREEN, 1));
addCommand(_cancel = new Command("Exit",Command.SCREEN, 2));
setCommandListener(this);
I have a problem with this. With the current code, the left soft key of the mobile device is getting assigned with 'LOGIN' and the right softkey is getting assigned with 'EXIT. Is there a way where I can swap the two i.e. can i have the left soft key of the mobile device to have the EXIT command assigned and LOGIN to the right soft key.
Any help would be a major contribution

Generally speaking, it's up to the device's implementation to decide where a Command will be placed. You have no way to directly assign a specific command to a specific soft-key. You can only "influence" the implementation's decision of where to put the Command, by using the commandType and priority parameters. If the Command's commandType is Command.EXIT, then the implementation will try to put the Command on the soft-button that is usually reserved for the "negative" commands (like "Back", "Exit", "Quit", "Cancel"). But the exact location depends on the phone and on the number and types of Commands you add to a screen.
You can try playing around with these values to get it on either side. I would recommend:
addCommand(_login = new Command("Login",Command.OK, 1)); // OK since it's a "positive" action
addCommand(_cancel = new Command("Exit",Command.EXIT, 2)); // EXIT since it's a "negative" actionshmoove
