Take a look at http://wicketstuff.org/wicket13/forminput/ and
http://cwiki.apache.org/WICKET/working-with-wicket-models.html
In your login form I would have private member variables userId and password
public class LoginForm extends Form {
private String userId;
private String password;
public LoginForm(String id) {
super(id);
setModel(new CompoundPropertyModel(this));
add(new TextField("userId"));
add(new PasswordTextField("password"));
}
public void onSubmit() {
System.out.println(userId);
}
//Make sure to add getters and setters
}

(as follow).

because the object o is null. How can I obtain the component of Login? Or
how can I use the method of Login?
