Newbie - Connecting MySQL with "AddressBook" Tutorial?

Hello Vaadin Lovers! -_-

This is the structure of this threat:
[b]

1 - My Goal
2 - Step by Step
3 -

QUESTIONS


[/b]
(for “Advanced Users” if they have time to explain us “why” or if they can apport some source where it explains this questions.)



4 - Original Source where we start from.

(You can also download the project from
HERE
)




1 - Goal for this threat.


Step 1: Only when I put right username and password.

Step 2: I get permision to see “AddresBookApplication”.




2 - Step by Step



Step 1:
We go to this link and search after the source of this example.

Authentification Source


Step 2:
We copy this source inside the link before.

private Layout buildLoginForm() {
    FormLayout layout = new FormLayout();
    // Create a label which we can use to give feedback to the user
    final Label feedbackLabel = new Label();

    final TextField usernameField = new TextField("Username");
    final TextField passwordField = new TextField("Password");
    passwordField.setSecret(true);

    // Add the login button
    Button login = new Button(Lang.getMessage("Login"),
            new ClickListener() {

                private static final long serialVersionUID = -5577423546946890721L;

                    }
                }
            });

    layout.addComponent(feedbackLabel);
    layout.addComponent(usernameField);
    layout.addComponent(passwordField);
    layout.addComponent(login);

    return layout;
}

Step 3:
And we paste it right here

Step 4:
Now we run it on the server.


Step 5:
And this is the result we get back!




3 -
Questions



Question 1: How can I say to the application. STOP!! First the Authentification and after run the Template!

Question 2: We don´t want to make a Advanced “User Admin Manager”. Where can i put Username: Test Password: 1234
