Connect to Google SQL from Google App Engine using hibernate

Question

I am trying to connect to my database from google cloud sql using hibernate, but I get the following error...

Caused by: java.lang.ClassNotFoundException: Could not load requested class : com.mysql.jdbc.GoogleDriver

but I have the dependency in the pom.xml

<dependency>
     <groupId>mysql</groupId>
     <artifactId>mysql-connector-java</artifactId>
     <version>5.1.38</version>
</dependency>

I call createEntityManagerFactory this way...

    Map<String, String> properties = new HashMap<>();

    properties.put("javax.persistence.jdbc.driver",
            "com.mysql.jdbc.GoogleDriver");
    properties.put("javax.persistence.jdbc.url",
            System.getProperty("cloudsql.url"));

    EntityManagerFactory emf = Persistence.createEntityManagerFactory(
            "Test", properties);

Could someone help me? Thanks

You need to put following into appengine-web.xml:

<use-google-connector-j>true</use-google-connector-j>

make sure it's declared on deployed version too

I resolved by changing the version of hibernate. Now I am using 4.2.0.Final and it works.
