I am posting the relevent files thanks for any help
I am using
Spring 3.1.0.RELEASE
hibernate-entitymanager 3.6.10.Final (Should work with JPA 2)
Trying to run the code from a JUnit file

Answer 1

I found the problem I had to add the datasource to the persistenceUnitManager something like this
<property name="persistenceUnitManager">
<bean class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManag‌​er">
<property name="defaultDataSource" ref="dataSource" />
</bean>
</property>

Answer 2

I was facing similar issue but was not using datasource in my case issue got resolved by adding hibernate key while providing database details in my persistence.xml file. Note that Hibernate 3.x and 4.x have different syntax as mentioned below (hit this while downgrading Hibernate 4.x to 3.x).
Changed below (Hibernate 4.x syntax) :
<properties>
<property name="javax.persistence.jdbc.driver" value="..."/>
<property name="javax.persistence.jdbc.url" value="..."/>
<property name="javax.persistence.jdbc.user" value="..."/>
<property name="javax.persistence.jdbc.password" value="..."/>
</properties>
With (Hibernate 3.x syntax) :
<properties>
<property name="hibernate.connection.driver_class" value="..."/>
<property name="hibernate.connection.url" value="..."/>
<property name="hibernate.connection.username" value="..."/>
<property name="hibernate.connection.password" value="..."/>
</properties>
