Hello Piyush, re: Authentication and Authorization APIs Every service has their own authentication API. Many are coming to use the OAuth standard although I've not seen many successful integration efforts yet. http://code.google.com/appengine/docs/java/oauth/
<http://code.google.com/appengine/docs/java/oauth/>There is google user authentication support into the appengine platform with this package: http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/users/package-summary.html The external services you are referring are out of the scope of this forum. You might want to research them directly. I've included some links to expedite your efforts. http://code.google.com/apis/accounts/docs/GettingStarted.html http://developers.facebook.com/docs/authentication/ http://developer.yahoo.com/auth/ Another resource that is is of broader scope and therefore more appropriate for many the issues you are going to face is http://stackoverflow.com/ BTW, I'm open for hire presently... <http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/users/package-summary.html> On Tue, Dec 28, 2010 at 2:14 AM, Piyush Zarkar <[email protected]> wrote: > Thanks Stevko for quick reply. > Your suggestions are really helpful to start with. > I have decided to select servlets for writing code, GWT for creating GUI as > you suggested. > But i am still confused how to authenticate google users , facebook users > ,yahoo users etc. Is there any authentication API ? > I am just collecting requirements at this moment.
