You need to add this property to the hibernate.cfg.xml

<property 
  name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

And you need to have mysql-connector-java jar at the class path.

Your transaction code is not correct (you don't use rollback, for an example). Refer this for how to properly work with that.
