Logging Google App Engine application

Question

I have made my GAE application using the development server, but now when I deploy it to GAE cloud, some features don\'t work (some elements are missing), but no exceptions

Answer 1

Google App Engine applications written in Java can write information to the log files using java.util.logging.Logger. Log data for an application can be viewed and analyzed using the Administration Console, or downloaded using appcfg.sh request_logs.

More info in the Logging documentation.
