## Google Cloud SQL/App Engine native Hibernate JPA demo

This demo contains an example program that shows how to use [Hibernate](http://www.hibernate.org/) [JPA](http://en.wikipedia.org/wiki/Java_Persistence_API) with native MySQL connections to connect from [Google App Engine](https://developers.google.com/appengine/) to [Google Cloud SQL](https://developers.google.com/cloud-sql) both in development mode and on App Engine.

## Requirements

* [Apache Maven](http://maven.apache.org) 3.0 or greater
* a local MySQL server (for running locally with devserver)
* JDK 7+

Clone this repository to a local directory.  Maven will download all the other dependencies.

## Deploying

To build, run:

mvn package

## Local deployment

Make sure the `demo` database exists on the local MySQL server.

To start the app, use the [App Engine Maven Plugin](http://code.google.com/p/appengine-maven-plugin/) that is included in this demo.  Just run the command:

mvn appengine:devserver

## App Engine deployment

In `pom.xml` update the following properties:

* `appengine.app.appId` to point to your App Engine application ID
* `cloudsql.url` to point to your Cloud SQL instance by replacing `your-instance-name` with the full name of your instance (this looks either like `my_project:my_instance` for non-domain specific instances or like `my_domain:my_project:my_instance` for the domain-specific ones).

Make sure the `demo` database exists on the Cloud SQL instance.

To deploy the app run the following command:

mvn appengine:update
