Hi,
There is a bug in the current Hibernate Entity Manager (3.1beta6). If the Persistence.creaeEntityManagerFactory() method doesn't get an options map it crashes (see http://opensource2.atlassian.com/pro...browse/EJB-124)

To workaround give an empty options map:

<bean id="entityManagerFactory1" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
		<property name="entityManagerName" value="TestEntityManager" />
                <property name="jpaProperties"><props></props></property>
</bean>

It should work,
