Re: What needs to be done after a successful login

I think it is worth deciding what you want to happen when the users credentials timeout (or are lost) on the server side.

Personally I hate it when Ajax/single page apps quietly fail when authentication has expired.

I'm new to GWT and a I have a problem, which I don't understand quite well. I'm making a GWT application where a user is required to log in. So I do my stuff, by checking the username and password if they match and so on.
But, on the onSuccess() method, what needs to be done in order to open the actual application ? I mean the current application is just the login screen with the DB connection. What needs to be done if they match, how do I open a new page, or a new application... ?

I understood that GWT basically is just a one-page application. Then how should I do this ? 

Thanks in advance.

DBConnectionAsync rpcService = (DBConnectionAsync) GWT.create(DBConnection.class);
ServiceDefTarget target = (ServiceDefTarget) rpcService;
String moduleRelativeURL = GWT.getModuleBaseURL() + "DBConnectionImpl";
rpcService.authenticateUser("admin", "admin", new AsyncCallback<User>() {
   public void onSuccess(User result) {
     // What to do here ?
   public void onFailure(Throwable caught) {
      // Failure
