Hi there, in Hibernate Search 3.1 online documentation we can see code samples like this:



However, getFullTextSession method requires an active transaction, doesn't it? The above code won't execute, right? We need something like:



Is this the correct way to use the getFullTextSession? In Hibernate Search 3.0, we didn't need to begin a transaction before creating a FullTextSession with the createFullTextSession method.

The first example is correct. You don't need a running transaction to get hold of a FullTextSession. What makes you believe that the code is not correct?

Because, if I try to run the first example, I get this:

Hmm, what type of session are you using? It seems you are using a transaction bound session outside a transaction. Have a look at this post viewtopic.php?t=972658

You also might find this general discussion of Hibernate's sesion management interesting: https://www.hibernate.org/42.html

So it all depends on your environment and setup you are trying to run in.

I think I still didn't get it. I'm using ThreadLocalSessionContext and I'm using the HibernateUtil approach to get access to the SessionFactory. I'm not running my program in a container. I didn't have any problems until I upgraded to Hibernate Search 3.1.1.

Funny thing is that I tested Hibernate Search 3.1.0, and I don't get the exception. It's only with 3.1.1. Why is that?

Hi,

I talked to Sanne and he thinks your problem could be related to HSEARCH-178

We will look into it.

Hi,
could you post the versions of other Hibernate libs involved?
I'd like to solve this but have never seen an error like

so I need to be able to reproduce first.

The other Hibernate libs versions I'm using are:

Hibernate Core 3.3.1 GA
Hibernate Annotations 3.4.0 GA
Hibernate Validator 3.1.0 GA

So the exception occurs with Hibernate Search 3.1.1 GA whenever I have code like this:



The same code works fine in version 3.1.0 GA.

Session session = HibernateSessionFactoryUtil.getSessionFactory().getCurrentSession();

Transaction tx = session.beginTransaction();

FullTextSession ftSession = org.hibernate.search.Search.getFullTextSession(session);
//ftSession.getTransaction().begin();
List<Guestbook> guestbooks = session.createQuery("from Guestbook").list();
for (Guestbook gb : guestbooks) {
ftSession.index(gb);
}
//ftSession.getTransaction().commit();
tx.commit();



I have the same problem with you .
Exception:
Exception in thread "main" org.hibernate.HibernateException: getListeners is not valid without active transaction.
What can i do next ?

Hello, I think I found the reason for this error.
This call is not legal when using a thread bound session.
I just found this javadoc on org.hibernate.context.ThreadLocalSessionContext, which is the kind of Session I guess you're using?

So this explains that, when using threadbound Sessions, you should always wrap it all in transactions, this includes the call to Search.getFullTextSession(session).

You're not experiencing this same problem in 3.1.0 because in 3.1.1 there was added a check to verify that you are actually using transactions, as many other people where having trouble because they forgot to start transactions, even when making changes to entities.
So sorry for the trouble in 3.1.1, the correct solution is to use transactions!

Hardy, do you think we could improve on this? The ThreadLocalSessionContext could be less strict on this checks?

If we want to change something in ThreadLocalSessionContext we should talk with Steve to make sure there are no side effects. What we should definitely do so is to update the documentation or add some warning/note. HSEARCH-437.
