Google App Engine is one of the supported Java environments for this library:

• Installation
• Auth Helpers
• Getting Started

Installation

Please read the Download and Setup instructions and put the library jars into your war/WEB-INF/lib directory.

Alternatively, Maven is also a supported option.

Auth Helpers

If you are planning to build a web app that interacts with a user's data via an OAuth 2.0 enabled API, we have created some helpers to assist you with the process.

The helpers aim to:

• Simplify the process of obtaining access tokens AuthorizationCodeFlow
• Manage the access tokens for you once they have been obtained by marking them as PersistenceCapable
• Easily make authenticated calls using the access tokens Credential
• Insulate yourself from the details of authentication when writing Servlets.

Getting Started

Please read the instructions on writing Google App Engine Applications and using OAuth2 with Google App Engine Identity.

We have built an example that combines our Java library and auth helpers to show you how easy it can be to access end user data from within an App Engine web app. This example also uses GWT for the UI.
