Problems setting up JPA2 (eclipselink)

[phe]

The configuration below gives me the following error when trying to persist an ent. If I use"org.springframework.orm.jpa.LocalEntityManager FactoryBean" at least that work.

If I use

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> 
    <property name="persistenceUnitName" value="driftsloggPersistenceUnit" /> 
</bean>

this entityManagerFactory instead it works. What is wrong in my configuration. Can someone share eclipselink spring configuration?

Thank you.
