java - How do I implement oAuth 2.0 in Google App Engine with RESTEasy? -

i developing google app engine rest service , want utilize oauth 2.0 authentication. added next code service methods check valid user , works in throws exception when not authenticated.

try { final oauthservice oauth = oauthservicefactory.getoauthservice(); final user user = oauth.getcurrentuser(); } grab (final oauthrequestexception e) { throw new runtimeexception(e); }

now want authenticate against command line programs written in java , python.

i have spent hours searching google , stackoverflow both , can't find single lucid illustration of how authenticate against gae application non-browser application makes sense. found lots of examples on how authenticate against google's own api's nil authenticating against own google app engine application.
