public abstract class AbstractAppEngineCallbackServlet extends AbstractCallbackServletBeta
This servlet fills in some of the required information for the AbstractCallbackServlet
with reasonable defaults for App Engine. It will default the servlet to creating UrlFetchTransport objects whenever an HttpTransport is needed. It will also default the
user identifier to the logged in App Engine user. This servlet requires that the App Engine user
must be logged in to work correctly. This can be accomplished by adding a security constraint in
your web.xml for the path at which this servlet will live.
Example that requires login for all pages:
<security-constraint>
<web-resource-collection>
<web-resource-name>any</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>*</role-name>
</auth-constraint>
</security-constraint>
Warning: starting with version 1.7, usage of this for OAuth 2.0 is deprecated. Instead use com.google.api.client.extensions.appengine.auth.oauth2.AbstractAppEngineAuthorizationCodeCallbackServlet.
