I make a RPC call in the login callback. Simplest case is to create a
RPC servlet that takes a username and password and returns a boolean
if a session was established. A more compilated service will return
error messages and maybe any initialization objects that are needed
right after login.

Another thing, how can I set the username and password to validation,
I wanna set the user and pass by database...

[Sandy McArthur]

class MyLoginListener extends LoginListener {
public void onSubmit(final LoginPanel loginPanel) {
final String username = loginPanel.getUserame();
final String password = loginPanel.getPassword();

final LoginServiceAsync loginService = LoginService.App.getInstance();

loginService.doLogin(username, password, new AsyncCallback() {
public void onSuccess(final Object result) {
final LoginResult loginResult = (LoginResult)result;

if (loginResult.isSuccess()) {
// Do your post login initialization
myApp.loadMainView(username);
} else {
// Login failed, try again
loginPanel.setErrorMessage(loginResult.getErrorMessage());
loginPanel.reenable();
}
}

public void onFailure(final Throwable caught) {
loginPanel.setErrorMessage(caught.getMessage());
loginPanel.reenable();
}
});
}
}

Does that help? I'm not sure what is unclear. It's just like anything
else you'd do with RPC in GWT.

I have no idea what "I wanna set the user and pass by database" means
from your other message.
