You need to enable sessions in the appengine-web.xml, <!-- HTTP Sessions are disabled by default. To enable HTTP sessions specify: --> <sessions-enabled>true</sessions-enabled>
<!-- It's possible to reduce request latency by configuring your application to asynchronously write HTTP session data to the datastore: --> <async-session-persistence enabled="true" /> <!-- With this feature enabled, there is a very small chance your app will see stale session data.
