Run Applications LocallyThe Eclipse Plugin allows to run applications for the
Google App Engine
locally in an environment which simulates the
environment on the App Engine.
You also have a local admin console(http://localhost:8888/_ah/admin/) which
allows you to see: your local datastore
the task queue,
inbound email and XMPP traffic.

Run Applications in Google CloudTo create an application on the Google App Engine, create an
application on
the Google App Engine website (https://appengine.google.com/).
Afterwards you can locally create an web application and uploadthis
application to the created application on the Google App Engine.
To create an application on theApp Engine press the button"Create an application" and select an application name. You have to
