How to make easy app for recognize faces in OpenCV 3.0.0. using Java?

edit

I need to make an app that will upload a picture with face and check if the face is in local database. If not then save the face under some name to the database. If there is the face, return back the name of the face. I need it in Java (Netbeans) with using OpenCV 3.0.0.

Is it possible? How to do it? Thanks for help.
