I have done some researching but I haven't find a clean explanation of how it all work.
I would like to know how does applicationa like Instagram, Wordcrack (online game), AirBnb and many other app have tier "Login with Facebook" done?
I currently work on the Java REST services that backups up an iOS app.
If some one already has done a similar things in their app/server I would really appreciate some help
I'm not looking for ready to use code answer but more of a general idea of the architecture to achieve this.
thank you!
I've done it in JavaScript, but the principle will surely be the same.
You have an API, provided by facebook. There are some information there :
https://developers.facebook.com/docs/apis-and-sdks#third-party-sdks
And, more than that, you have declare your own app on facebook. This has, for me, 2 goals :
provide the url of your server, so when you'll call facebook with the
login information, he will know where to redirect
specify the access your app need.
When i've begun to watch this, i've discovered satellizer. I think that's a good entry point to understand how it works with an example :

Hope this help.
Supporting login through their website (Facebook,Twitter,Instagram etc) allows a user to use his already active profile to signup to a portal or an app. This way a user experience is enhanced and having to have separate login credentials for different apps and sites are reduced.
A developer utilizes the APIs or SDKs that these social networks expose to let you integrate it in your app and provide an easy sign up process to your users.
we are building a website using Liferay and we need to Implement CAC authentication. I put in a ticket with Liferay customer support, but they would not offer a path forward, because they do not "officially" support this feature. Can anyone please tell me the best way to go about doing this?
The best resource I've found so far is a blog, at the following url talking about building a custom hook. Unfortunately, they do not give very much information on how to build and implement it.

Thanks for your time and any assistance you can offer.
Sorry, I can't help with the hook.
Afaik smart cards are supported by LDAP. So you could setup active directory like this:

I've recently found an open source library that does, post on a users facebook wall(restfb and facebook4j)
All of them does the necessary things, but there's one thing left I need to do and that is to login and register users to my web application using their facebook account. are there any related frameworks for such task? if not, please provide alternative solutions
If i am correct in my understanding, all you want is to use Oauth or Open Id system to let user register and login to your website using Facebook or any other such service provider.
If i am correct in my understanding, there is a very good library which is quite easy to use and very light weight.
Scribe-Java
It also contains few examples which shows how to use it and how it works, let us know if this is what you are looking.
I need to authenticate the users who visit my java based web app (Servlets and JSP) using different social media like facebook, twitter, google and yahoo.
Is there any open source library which solves this problem? Instead of working on different API's an open source java library would be helpful.
The guys from SpringSource have a library doing what you ask for, called Spring Social. The linked blog article explains what it does with some nice examples. But the project is still in beta (even though the quality of their deliverables has always been rock solid).
Take a look at openid4java.
This library allows you to OpenID-enable your Java webapp.
You can use Open ID with openid4java.
I want to integrate paypal in my java web application. I saw that they offer many methods to accomplish this. But i want my visitors to remain on my site only. My friend told me that Paypal offers webservice. But i can't seem to find any documentation on Paypal site. If anybody could help me with this, i would be really very grateful. Please offer me the relevant links on Paypal where i could read and get my things done.
Secondly, my friend also told me that we need to give location to paypal where my visitors would be redirected once paypal payment is complete. But i am confused. I am working on localhost. How would Paypal know about my localhost?
I have already created my sandbox testing account. What should be my next step. Please explain me in detail. I don't know anything about Paypal. Once i created a demo application of Express checkout where they give a simple button of Pay Now and on clicking on it shopping cart etc appears. But now i want my visitors to stay on same website.
Thanks in advance :)
