Hi,

We just switched from oc4j 9.0.4 to 10.1.2 and and now getting this wierd behaviour.

14:43:58,731 FATAL [HibernateSessionDispenser] fatal persistence error while creating hibernate session for /hibernate.cfg.xml: Could not locate TransactionManager

In the hibernate.cfg.xml we have specified OrionTransactionManagerLookup


What should we change to avoid this error?

Thanks

Without all the details, my suspicion (only because I just encountered a similar problem with Websphere) is that you have a CMT in which you are trying to use Hibernate Transaction API?

I think there is some differences in the interpretation of the specification, but, the latest release of both Oracle and IBM's Application Servers appear to not allow you to access the usertransation from within a CMT. Hibernate expects the UserTransaction to be available, hence the error in your stack trace.

Websphere provides an extendedJTATransaction API that allows you to tie back to the UserTransaction in a propietary fashion. Perhaps OC4J has something similar.

I am trying to do the same thing using hibernate 3.0.5 without success, when I try to do some transactional stuff, the folowing exception is thrown:

How can I use Hibernate + OC4J + CMT?

Thanks

Hi.
I have same problem.
I use oc4j 10g (10.1.2.0.0).

My hibernate.cfg.xml:
<property name="transaction.manager_lookup_class">
org.hibernate.transaction.OrionTransactionManagerLookup
</property>
<property name="transaction.factory_class">
org.hibernate.transaction.CMTTransactionFactory
</property>

<property name="flush_before_completion">true</property>
<property name="auto_close_session">true</property>
<property name="release_mode">auto</property>

After call build session factory:
sessionFactory = new Configuration().configure().buildSessionFactory();
I will get same exception as Chotasher.

I use EJB session bean with CMT transaction type.

Where is the problem? Thanks.

I was reading the EJB 2.0 spec and I found one interesting thing in the section 17.6.2.10:

Handling of getUserTransaction() method
If an instance of an enterprise bean with container-managed transaction demarcation attempts to invoke
the getUserTransaction() method of the EJBContext interface, the Container must throw the
java.lang.IllegalStateException.

Is it the problem? Hibernate is doing something illegal according to the spec? Or the UserTransaction its not not taken from the Context? So where is the problem?

Thanks,

Ok, the solution is to use JDBCTransactionFactory and ommit hibernate.transaction.manager_lookup_class and/or jta.UserTransaction.

But doing this, you'll must flush and close Session explicity.

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<property name="use_outer_join">true</property>

<property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>

<property name="hibernate.cache.use_query_cache">true</property>

<!-- It won't work at all -->
<property name="hibernate.connection.release_mode">auto</property>
<property name="hibernate.transaction.auto_close_session">true</property>
<property name="hibernate.transaction.flush_before_completion">true</property>
<!-- /It won't work at all -->

<mapping resource="Account.hbm.xml"/>
</session-factory>
</hibernate-configuration>

If using Hibernate 3.x, try to change your

<property name="transaction.manager_lookup_class">net.sf.hibernate.transaction.OrionTransactionManagerLookup</property >

to

<property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.OrionTransactionManagerLookup</property>

Hi, thank you for the answer, but it is not working yet.
Using the factory org.hibernate.transaction.JDBCTransactionFactory, it works well, but I need to flush() every time I change data on my objetct.

For performance reasons, it is desirable to flush only on transaction commit. Do you know what can I do for?

Thanks a lot.

You can use OC4JTransactionManagerLookup.java in following link to fix the exception:

Hi, thank you, when we solved the problem, I've changed transaction manager lookup class and now it is working. Anyway, it's nice to see we have a new version.
