Folks,

I am a bit confused on how to use user services correctly.

Here is the relevant code snippet:

public class GreetingServiceImple extends RemoteServiceServlet implements 
GreetingService {
   
   public string greetServer() {
        UserService us = UserServiceFactory.getUserService();
        User user = us.getCurrentUser();
        ...
   }
}

The problem is, the value returned by getCurrentUser is always null, 
irrespective of whether I deploy locally or at appspot.

I am using Firefox as the client. I have two tabs open. On one tab, I am 
signed into Google mail using my gmail account. On the other tab, I am 
trying to run the app that I am working on.

What is it that I am missing?

Thank you in advance for your help.

Regards,
Peter
