google app engine connect to external database

[Luciano Lopes]

Hello people. I have two Java projects running on AppEngine, one of the projects has a MySQL instance and is already connected to AppEngine. I would like both projects to connect to the same database. I've already activated the Cloud SQL APIs, Cloud SQL Admin even so it didn't work, I'm getting the following error:

{

     "code": 403,

     "errors": [

         {

             "domain": "global",

             "message": "The client is not authorized to make this request.",

             "reason": "notAuthorized"

         }

     ],

     "message": "The client is not authorized to make this request."

}

can you help me?

Try this:

Go into the iam-admin for the project  you want to give access to the DB and look for the service account it would be something like [project_id]@appspot.gserviceaccount.com, copy it, then in the same page, change the project to the one that hast the MySQL instance and clic Add+ and give the service account the Cloud SQL Client role. 

Cheers
