Where to store global (application) variables?

In my application I need to store in somewhere a variable "user" where
I want to store the session user data.

Should I do something like this:

Or should I use GIN and should I do something like this?

public class MyAppClientModule extends AbstractGinModule {
protected void configure() {
bind(User.class).in(Singleton.class);
}
}

Or sould I use ClientFactory and ClientFactoryImpl and store in my
ClientFactory my session user data.

I am using GWT 2.0 MVP framework.
