Integrating Picketlink with REST API

[mksmanjit]

Hi Team,
I am using Picketlink with my tomcat project and its working fine with the web, Now i am planning to integrate Picketlink with REST API, currently i am using OAuth 2.0 in REST API.

Can you please help me in this, which Jar i need do integrate with REST API and is there any demo where it is implemented.

I tried followed https://developer.jboss.org/wiki/PicketLinkRESTAPI but i did't see where it is authenticating with IDP server..

Thanks in advance..
