I need to develop following functionality for my JSF web application:
Authenticating users through external providers like Gmail, Hotmail, Yahoo, Twitter, Facebook, LinkedIn, Foursquare, MySpace
Importing their contacts from them (Gmail, Yahoo)
I am planning to use SocialAuth Java library for the same, can some one how has used them tell me about your experience with it?
If someone know some better approach for the same, please let me know!
