I created a sample application in playframework 1.2 and tried to deploy it to google-appengine, the deployment showed no issues. but when I hit my application, it shows a 505 error.
when I checked the logs, I found that its throwing an error, and coming to the funny part, it shows a servlet exception, huhh! play is totally out of servlet/jsp world. how come it throws servlet exception?
The full stack trace is
