Auto Flush not working for Spring 3.1 LocalEntityManagerFactoryBean+Hibernate 4+JTA

[adrianshum]

(I am asking the same question at StackOverflow too:
http://stackoverflow.com/questions/1...bean-hibernate )


I have did a lot of search on the web and pages like this and this and this mostly suggested for using CMTTransactionFactory. However I am still unable to make it work (I wonder if it is because I am creating a EM using a LocalContainerEntityManagerFactoryBean instead of creating Hibernate session by LocalSessionFactoryBean)

Here is what I have in my app ctx

<jee:jndi-lookup  id="dataSource" jndi-name="jdbc/fooDs" />

<bean id="transactionManager"
    class="org.springframework.transaction.jta.WebSphereUowTransactionManager" />

<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect" />
        </bean>
    </property>
    <property name="persistenceUnitName" value="foo" />
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.foo" />
    <!--
      <property name="persistenceXmlLocation" value="classpath:/META-INF/test-persistence.xml" />
     -->
    <property name="jpaPropertyMap">
        <map>
            <entry key="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
            <!--
              <entry key="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereExtendedJTATransactionLookup" />
              <entry key="hibernate.transaction.factory_class" value="org.hibernate.transaction.CMTTransactionFactory"/>
             -->
            <entry key="hibernate.transaction.factory_class" value="org.hibernate.engine.transaction.internal.jta.CMTTransactionFactory"/>
            <entry key="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.WebSphereExtendedJtaPlatform"/>
            <entry key="hibernate.transaction.flush_before_completion"  value = "true" />
        </map>
    </property>
</bean>

(In jpaPropertyMap, I tried to have the two remarked entries and still the same)

I am making use of Spring Data JPA and after the entity is retrieved, I updated the content. If I am not flushing the repository (which means session/entityManager) manually, it simply discard my changes.

Can anyone give me some hints on what I have missed in the setting? Is there anything special to notice for using LocalContainerEntityManagerFactoryBean?

I am using Spring 3.1.2.RELEASE, Hibernate 4.1.6.Final, Websphere 8
