Try with these changes to your transaction manager configuration (I'll only list the parts that need to be changed):
<tx:annotation-driven transaction-manager="txManager"/>
...
<bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
