Spring @Transactional не создание необходимой транзакции

Хорошо, таким образом, я наконец поклонился давлению со стороны окружающих и начал использовать Spring в своем веб-приложении :-)...

Таким образом, я пытаюсь заставить материал обработки транзакции работать, и я просто, может казаться, не получаю его.

Моя конфигурация Spring похожа на это:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
                           http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/tx
                           http://www.springframework.org/schema/tx/spring-tx.xsd">

    <bean id="groupDao" class="mil.navy.ndms.conops.common.dao.impl.jpa.GroupDao" lazy-init="true">
        <property name="entityManagerFactory" ><ref bean="entityManagerFactory"/></property>
    </bean>

 <!-- enables interpretation of the @Required annotation to ensure that dependency injection actually occures -->
  <bean class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"/>  

  <!-- enables interpretation of the @PersistenceUnit/@PersistenceContext annotations providing convenient
       access to EntityManagerFactory/EntityManager -->
  <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>

  <!-- uses the persistence unit defined in the META-INF/persistence.xml JPA configuration file -->
  <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="CONOPS_PU" /> 
  </bean>

  <!-- transaction manager for use with a single JPA EntityManagerFactory for transactional data access
       to a single datasource -->
  <bean id="jpaTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
      <property name="entityManagerFactory" ref="entityManagerFactory"/>
  </bean>

  <!-- enables interpretation of the @Transactional annotation for declerative transaction managment
       using the specified JpaTransactionManager -->
  <tx:annotation-driven transaction-manager="jpaTransactionManager" proxy-target-class="true"/>

</beans>

persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

  <persistence-unit name="CONOPS_PU" transaction-type="RESOURCE_LOCAL">

    <provider>org.hibernate.ejb.HibernatePersistence</provider>

    ... Class mappings removed for brevity...

    <properties>

    </properties>

  </persistence-unit>

</persistence>

Метод ДАО для сохранения моего объекта области похож на это:

    @Transactional(propagation=Propagation.REQUIRES_NEW)
    protected final T saveOrUpdate (T model)
    {
        EntityManager em = emf.createEntityManager ( );
        EntityTransaction trans = em.getTransaction ( );

        System.err.println ("Transaction isActive () == " + trans.isActive ( ));

        if (em != null)
        {
            try
            {
                if (model.getId ( ) != null)
                {
                    em.persist (model);
                    em.flush ();
                }
                else
                {
                    em.merge (model);
                    em.flush ();
                }
            }
            finally
            {
                em.close ();
            }
        }

        return (model);
    }

Таким образом, я пытаюсь сохранить копию своего объекта Группы использование следующего кода в моем тестовом сценарии:

    context = new ClassPathXmlApplicationContext(configs);
    dao = (GroupDao)context.getBean("groupDao");

    dao.saveOrUpdate (new Group ());

Это бомбит за следующим исключением:

Кроме того, я получаю соблюдающие предупреждения, когда Spring сначала запускается. Так как они ссылаются на entityManagerFactory и transactionManager, у них, вероятно, есть некоторое влияние на проблему, но я имею не смогший для дешифровки их достаточно для знания что:

У кого-либо есть какая-либо идея, что я пропускаю? Я полностью озадачен...

Спасибо
