Re: What needs to be done after a successful login

We shared our code here https://github.com/salk31/gwt-rf-queue which does what jhulford suggested.

Our company as a single sign on (jasig CAS) so quite often the app can just popup up the CAS (in an iframe) and without user interaction login the user back in then retry the request.

If you can funnel your remote calls through a single remote implementation (.ie you can have your async interfaces extend from a common abstract class), you can throw an authentication exception when the user's credentials have expired, catch it client side and toss up a login dialog over top of the current page to have them log in again and then resend the previous command that failed with the authentication error after they've signed back in.  This gives the user a seemless experience of re-logging in without losing their current place in the app.  

I feel that's the best user experience for handling timed out users unless, of course, you need a higher security option of clearing everything the user is doing once their credentials expire - like in banking apps, etc.

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.

Hello,

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";

target.setServiceEntryPoint(moduleRelativeURL);

rpcService.authenticateUser("admin", "admin", new AsyncCallback<User>() {

   @Override

   public void onSuccess(User result) {

     // What to do here ?

   }

   @Override

   public void onFailure(Throwable caught) {

      // Failure

   }

});
