I have the following configuration. Hibernate seems to be missing the batch configuration.

<persistence-unit name="hbrnt" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>

<class>org.batoo.jpa.benchmark.Country</class>
<class>org.batoo.jpa.benchmark.Person</class>
<class>org.batoo.jpa.benchmark.Address</class>
<class>org.batoo.jpa.benchmark.Phone</class>

<properties>
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.Driver40" />
<property name="hibernate.connection.url" value="jdbc:derby:memory:H;create=true" />
<property name="hibernate.connection.username" value="sa" />
<property name="hibernate.connection.password" value="" />
