Hi im using hibernate-search-3.1.1.GA

with the following simple Code :

@Indexed(index="tags")
public class Tag {

@DocumentId
private int id;
...
}

hibernate.cfg :
...
<property name="hibernate.search.default.directory_provider">org.hibernate.search.store.FSDirectoryProvider</property>
<property name="hibernate.search.default.indexBase">lucene/indexes</property>
<property name="hibernate.search.indexing_strategy">manual</property>
...
IndexUpdateCode :

Session session = HibernateUtil.getSession();
session.setFlushMode(FlushMode.MANUAL);
session.setCacheMode(CacheMode.IGNORE);

FullTextSession fullTextSession = Search.getFullTextSession( session );

fullTextSession.purgeAll(Tag.class);
for(Object o:fullTextSession.createCriteria(Tag.class).list()){
fullTextSession.index((Tag)o);
}

witch results in the following Exception :

and i am unable to to track this error down ;(

So any ideas ? :)

Update :

The Problem was caused by hibernate search not freeing all resources after closing the hibernate session factory.

I used something like this

sessionFactory.open();
...
sessionFactory.close(); <--- hibernate Search IndexWriter is closed but not freed
...
sessionFactory.open(); <-- hibernate Search still use the closed IndexWriter

FulltextSession.index(blub); <--- Work gets scheduled

....
session.getTransaction.commit(); <--- BOOOM : hibernate Search trys to write on a closed Index

> : )

Hi,

I seem to be having exactly the same problem; everytime I close an hibernate session I call sessionFactory.close() and - BOOM- I get the same exception.

Could you possibly tell me how did you fix it and any workarounds that might help?

Im using Hibernate Search 3.1.1 GA as well..

Regards,

Francisco Rodríguez

i fixed my problem by closing the sessionFacotry first
than calling cleanup for all fulltextindexeventlistner by hand ( u need to save a instance of the hibernate configObject )

for (FlushEventListener fl : config.getEventListeners().getFlushEventListeners()) {
if (fl instanceof FullTextIndexEventListener) {
((FullTextIndexEventListener) fl).cleanup();
}
}

and after all i set the config to null and the sessionFacotry instance to null

Well thank you very much, that does seem to work...

However, I would prefer not having to set the conf to null, taking into account that I have to build a new session factory every time I open a new Hibernate session and its better if I dont have to read the configuration file again.

Any other ideas?

Thanks in advance.

normaly its a realy rare case that u have to close the sessionFactory in a normal application.
a u really sure u have to close it so often that re reading the config is such a problem ?

maybe u can read all config properties to a properties object and apply theam after building a new config.


java.util.Properties poperties;
Enumeration<Object> keys=properties.keys();

while(keys.hasMoreElements()){
String key=(String)keys.nextElement();
config.setProperty(key, properties.getProperty(key));
}

Well we will check again if it is necessary to close the session so often. If we do, I'll give it a try to your solution.

If I learn about any other solutions I will post them here as well.

Again, thank you very much.

Francisco Rodriguez Drumond

I'm sorry for the late answer, we from the Search team don't notice all posts on the wrong forum. Hibernate Search related questions should be posted on the Search forum.

If you still need help, please post to the correct forum.
