Keeping on trying to fully understand GAE Authentication, with the Expenses example approach, I find these lines of code:
UserService userService = UserServiceFactory.getUserService(); ... if (!userService.isUserLoggedIn()) { ... } And now I get stuck into this. - What is that UserService? Ok, it´s the interface com.google.appengine.api.users.UserService. - But how does it work? How can it check if a user is logged in? where the hell does it get the users from? Thank you in advance. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
