FullTextIndexEventListener not triggered on update

Hi,

I'm using Hibernate search 3.1.0 with Hibernate Core 3.3.1 GA and Spring without Hibernate annotations.

Following the documentation I have registered event listeners like this :

<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">com.itesoft.share.model.HSQLDialectExt
</prop>
<prop key="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider
</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.show_sql">true</prop>


<prop key="hibernate.search.default.indexBase">${ftindex.location}/dev</prop>
<prop key="hibernate.search.analyzer">custom_analyzer</prop>
</props>
</property>

<property name="eventListeners">
<map>
<entry key="post-update" value-ref="indexListener">
</entry>
<entry key="post-insert" value-ref="indexListener">
</entry>
<entry key="post-delete" value-ref="indexListener">
</entry>
<entry key="post-collection-recreate" value-ref="collectionSearchListener">
</entry>
<entry key="post-collection-remove" value-ref="collectionSearchListener">
</entry>
<entry key="post-collection-update" value-ref="collectionSearchListener">
</entry>
</map>
</property>

</bean>

Entities are annotated @Indexed and (it seems) are properly configured because everything works fine when they are indexed on application start up.

On entity insertion, the index are updated and search is retrieving newly created entities.

But index is not updated after an entity update. I have checked it with Luke, modified values are not reflected in the index files.

The entity update code is :

Code:

@Transactional(readOnly = false, propagation = Propagation.REQUIRED)
    public void update(final Entity entity) throws DAOException
    {
   LOG.debug("saving or updating entity instance");

   try
   {
       // Updating entity to database
       getSession().merge(entity);
       LOG.debug("persist successful");
   }
   catch (HibernateException re)
   {
       LOG.error("persist failed", re);
       throw new DAOException(re);
   }
    }

We are using "merge" method.

Any guess of what is missing in the configuration or code to trigger the index files update ?

Thanks,
Best regards,
Eric

Hi,
This kind of problems are usually related to not having the transactions configured correctly.
take a look into https://www.hibernate.org/441.html,
especially

Code:

<bean id="transactionManager"
        class="org.springframework.orm.jpa.JpaTransactionManager">

I looked at this link before posting the message, but it doesn't apply to my case because I don't use org.springframework.orm.jpa.JpaTransactionManager as a transaction manager. I use : org.springframework.orm.hibernate3.HibernateTransactionManager (I use hibernate Core without annotations, no JPA).

Switching to JPA could be nice, but it is not scheduled yet on the project roadmap.

Do you have any other docs I could check in my case ?

Thanks for your reply,
Eric

I have understood what is happening.

I am indexing 2 associated entities : Doc and Idx.

Doc is referencing idx through a Set<Idx> property. Both entities are @Indexed. The Set<Idx> property (named idxes) is @IndexEmbedded annotated.

I have not activated update & merge cascading. So when I need to update Idx I do it directly. Idx index files are updated, but not those of Doc, and I search on Doc.

I would like the Doc.idxes index file entries also updated when Idx index file are updated by listeners. Is it possible ? How ?

Best regards,
Eric
