Hi Ryan,

Thanks for this valuable post, it really saves a lot of my time. Only question is can you show me your declaration for "entitymanagerfactory" in spring?

Only now saw that some of my message was blocked before the "" element is of course the persistence-unit-ref element

Hi Ryan,
Thanks a lot for your post, it's a lot of help but I have a question: How should I use this when I'm running an EAR with no WAR? There is no web.xml file to put the "" element in and I'm not sure where I can use it.
Do you have any leads for me?
Thanks in advance,
Ittai

Are you using GlassFish? Did you configure Spring to know about both persistence units? In my example they were called MyPU1 and MyPU2. Also, in your code are you specifying the persistence unit name like this: @PersistenceContext(unitName = "EVoucherPU") I'm not sure what else to ask because the above configuration works for me on several projects.

@Mathew: sorry I don't have a sample project. It was copied from a closed source project and modified for this blog entry.

2010-02-01T15:13:50.651-05:00

I agree with you about Spring's doc.

I've always been working with EJB and I begin with Spring.

In these few days, I feel that to give a single step means 'more effort and risk that goes wrong'.

Maybe it's just the beginning and then see more clearly :P:P

Thanks again.

Great, I am happy to have been able to help you. I think I do understand how much I helped you because I spent weeks screwing around with Spring XML config files and in forums trying to get JPA + JTA working before I found the solution in this blog entry. That experience made me realize how much simpler Java EE can be, because everything works out of the box -- no integrations necessary. SpringSource's documentation assumes you are running in Tomcat and doesn't help in scenarios like this one.

Thank you very much, really. In every forum I rea...

Thank you very much, really.

In every forum I read, I was given many solutions to change Spring File Config, but none worked for me. I was desperate

Do not know how much you have helped me.

Thanks again from Spain. Jes.G.P.

2010-01-29T08:07:19.958-05:00

Since you are using Hibernate instead of the default JPA provider, you need to tell Hibernate what transaction manager to use. In your persistence.xml, make sure Hibernate has this property:

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