How to use Hibernate locally in development mode

Hi,

i'm trying to get hibernate with my gwt-application to run. I followed this tutorial and the example works on app engine:

https://developers.google.com/appengine/articles/using_hibernate

But if i try to run this locally in eclipe, i get the following error.

Caused by: javax.persistence.PersistenceException: No persistence providers available for "com.google.cloudsqldemo.jpa" after trying the following discovered implementations: NONE

Can some give me some advice how i can get this running locally as well?

Thanks and best regards

Jan
