Google App engine external database
database, google-app-engine, java
Solution
The closest thing that you will find is the Google Secure Data Connector. All connections outbound from GAE are HTTP based, so you're very unlikely to get a jdbc type connection to a database server (MySql, SqlServer, etc).
Problem
I've been searching and can't find an answer anywhere. I also haven't had time to try it out either. Is it possible, using java in the Google App Engine (GAE), to connect to a remote database. Whether it MySql, SQLServer, etc. Will it be allowed to make calls outside of it's domain? Is it possible to even use the required libraries to make such a connection?
