I have created RESTful services in java/netbeans using the Jersey Library. Now i want to secure this service using oAuth 2.0.
Are there any libraries or any tutoria
Check this example Jersey + Oltu + Oauth: https://bitbucket.org/dobromyslov/oauth2-example/src/
Explanation how it works is located here:

You can use Apache Oltu (formerly Apache Amber): https://cwiki.apache.org/confluence/display/OLTU/Documentation
The Authorization Server and Resource Server sections explain how to secure your REST services.
We used spring security, think is the simple and easiest way, look here for more information:
