Is redeployment possible?

I created one web application in eclipse an开发者_运维技巧d successfully deployed it on google app engine. Then i do some modification in my program. How to do changes in the deployed application. Is their any option for redeployment?

If you have the google app engine plugin just click on the deploy button and it will re-deploy the whole application.

1. Update the version number in appengine-web.xml.
2. Re-deploy using the Google App Engine Eclipse plugin.
3. Go to the Admin console and set the new version as the default.

Voilà! You have just updated your app!
