JPA, JTA GlassFish - No transaction is currently active exception

[fericit.bostan]

I'm using Spring 3.0.2 with EclipseLink 2.0 and GlassFish 3.0.1. I'm having a Transaction issue that is preventing me from inserting data into the database tables. I've annotated my Dao classes with the following on the class:

@Transactional(propagation = Propagation.REQUIRED)

My BaseDao contains the annotation for the @PersistenceContext as follows:

    @PersistenceContext
    public void setEntityManager(EntityManager entityManager) {
        jpaTemplate = new JpaTemplate(entityManager);
    }

My aplicationContext.xml file has the following definitions:

    <context:annotation-config />

    <tx:jta-transaction-manager />

    <tx:annotation-driven/>

    <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor">
        <property name="persistenceUnits">
            <map>
                <entry key="my-pu" value="persistence/my-pu"/>
            </map>
        </property>
        <property name="persistenceContexts">
            <map>
                <entry key="my-pu" value="persistence/my-pu"/>
            </map>
        </property>
    </bean>

and my test-applicationContext.xml has the following:

    <bean id="entityManagerFactory"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="jpaVendorAdapter">
            <bean
                class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter">
                <property name="showSql" value="true" />
            </bean>
        </property>
        <property name="jpaDialect">
            <bean
                class="org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect" />
        </property>
        <property name="persistenceUnitName" value="my-pu"/>
        <property name="persistenceUnitManager">
            <bean 
                class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager"/>
        </property>
    </bean>

Things seem to be working except nothing commits to the database. I've stepped through the Spring code and I have confirmed that the JtaTransactionManager is indeed retrieved from the GlassFish container. So I decided to force a flush() on the JpaTemplate, but this raised an exception from the EclipseLink EntityManager and stated that there is no active Transaction.

My container is a GlassFish embedded and the TransactionManager is an active JtaTransactionManager. I step through the Spring code and I can see the interceptors begining the transaction and committing it when it is suppose to. So why does EclipseLink not know about the active Transaction?

I have the following specified in my persistence.xml file:

  <persistence-unit name="my-pu" transaction-type="JTA">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <jta-data-source>jdbc/myDataSource</jta-data-source>

So EclipseLink is expecting a JtaTransaction to be running, which it is, and I can see that Spring is actively managing my transactions with the JtaTransactionManager retrieved from GlassFish JNDI. Actually, it is performing the lookup using:

    <tx:jta-transaction-manager />

and it appears that Spring is locating the TransactionSynchronizationRegistry, so it's clear that there is a JtaTransactionManager and the transaction is being started and committed by Spring. So why doesn't EclipseLink see it?

Thanks for the help...
