Hi All,
We recently upgraded from Hibernate 3 to Hibernate 4. We are using Spring 3.2.0 M1 with Hibernate. Initially we were setting Hibernate properties as

<prop key="hibernate.transaction.factory_class">com.atomikos.icatch.jta.hibernate3.AtomikosJTATransactionFactory</prop>
<prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup</prop>

But after upgrading to Hibernate4,

Can anyone here please tell me for the property "hibernate.transaction.manager_lookup_class" what corresponding class should I set?

Thanks,
Vivekanand Alampally..

Sorry, I missed some text in previous post,
In hibernate properties, initially we were setting propeties as
       
    <prop key="hibernate.transaction.factory_class">com.atomikos.icatch.jta.hibernate3.AtomikosJTATransactionFactory</prop>
    <prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup</prop> 
                   
    But after upgrading to Hibernate4,
    
    <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</prop>
    
    Can anyone here please tell me for the property "hibernate.transaction.manager_lookup_class" what class should I set?

I posted this topic in official Spring & Hibernate forums

 http://forum.springsource.org/showthread.php?128268-Upgrading-for-Hibernate-3-to-Hibernate-4

 https://forum.hibernate.org/viewtopic.php?f=1&t=1016892

The same class as before, lookup did afaik not change.
Do you have any problems with this class?

Like documented here:

http://www.atomikos.com/Documentation/HibernateIntegration#With_JPA

You should only remove the jta factory class, lookup class should be left untouched.

Thanks Torsten Krah for your response,

After setting the property,
 <prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup</prop>

I am getting the following exception..

HHH000427: Using deprecated org.hibernate.transaction.TransactionManagerLookup strategy [hibernate.transaction.manager_lookup_class], use newer org.hibernate.service.jta.platform.spi.JtaPlatform strategy instead [hibernate.transaction.jta.platform]

So, Can you please tell me, how to get rid of this exception.

Hi Vivekanand,

this is a warning not an exception. If hibernate handle the compatibity properly I suppose this should continue tu work

To get rid message, I suppose we have to write our Impl of org.hibernate.service.jta.platform.spi.JtaPlatform.

Regards

This is my  full configuration with Hibernate 4. Works for my project. I hope this will help you.
