@Beta
public abstract class AbstractAppEngineFlowServlet
extends AbstractFlowUserServlet

Beta
This class fills in some of the unknowns of the generic AbstractFlowUserServlet with reasonable defaults for App Engine. This servlet requires that the App Engine user must be logged in to work correctly.

Warning: starting with version 1.7, usage of this for OAuth 2.0 is deprecated. Instead use AbstractAppEngineAuthorizationCodeServlet.

Upgrade warning: in version 1.15 there was an implementation of AbstractFlowUserServlet.newJsonFactoryInstance() that used com.google.api.client.json.jackson.JacksonFactory, but starting with version 1.16 there is no such implementation.

Since:

1.4
