[google-appengine] Endpoints java 404 unsupportedProtocol

[Alberto Giantin]

Hi all, I've developed a web application using maven and appengine. I have 
some problems with cloud endpoints, everything works fine in my local 
machine but when I deploy to appengine I've a strange response calling 
endpoints. I'm new to appengine and I don't if I am doing something wrong. 
I've attached some files.
This is what is going wrong:

Request

GET https://soccer5manager.appspot.com/_ah/api/manager/v1/matches

X-JavaScript-User-Agent:  Google APIs Explorer

 Response
