I work in a project using GAE.
I have a GAE app that consume Rest services from others GAE apps (this apps uses different Google Apis with 2LO oauth2, eg: one app uses Gcalendar Api, other Gmail Api, ...). The REST apps are in Java and use GoogleCredential for consume Google Apis. All the apps are in same domain (Company is own of all projects).
I need migrate the principal GAE app (also in Java) from 2LO Oauth 1 to 2LO Oauth2.
I see this example but not is 2LO. https://code.google.com/p/google-oauth-java-client/wiki/Samples
Can I use Credential from Google-Oauth-api or GoogleCredential? Or GoogleCredential is only for Google Apis?
Thanks.
