If you've tested your application locally and are happy with the results, you're
only a few clicks away from deploying it directly to Google's servers. Just click
the
Deploy App Engine Project
button on the toolbar.

You'll need to enter your Google account email address and password (don't worry - we don't store your password on disk). Then just click Deploy.
Note: If the deploy dialog displays an error message indicating you your application is missing an application ID, you'll need to set it by clicking the App Engine project settings... link at the bottom of the dialog.
During the deployment process, you'll see a progress dialog and detailed output in the Console view. If your application uses GWT, the plugin will automatically perform a GWT compilation using the settings from the GWT Compile dialog.
Once the upload is complete,
you should see the message "Deployment Successful" in the console. Then browse directly to your live
application at http://application-id.appspot.com.
