I am starting to try and learn how to use the google app engine with java. The first roadblock I hit (seems trivial but I can't find an answer anywhere) is logging in. I know how to use the screen google provides you (userService.createLoginURL(req.getRequestURI())) but that only gives you a screen that has one field for the user's email address. Is there some way to ask for a password and check with google so that the user is actually logged in? As it is you can type anything you want in the box. Thanks for the help in advance and sorry if this is covered elsewhere I just can't find it right now.
