OpenEJB and Hibernate
Hi guys,
I tried to use Hibernate in OpenEJB (our application unfortunately
still does not use JPA - it uses Hibernate directly instead). However,
it seems there is a version clash: OpenEJB requires ASM 2.2.3 while
Hibernate 3.2.4 requires ASM 1.5.3 and they seem to be incompatible:

Have you guys tried to use OpenEJB with Hibernate? Can you please
provide me with some hints? Which one is harder: modify Hibernate
to use 2.2.3 or OpenEJB to use 1.5.3? :-)
Many thanks!

Hi Jacek,
thanks for reply ;) Well, we are moving our application to a JEE
environment. The application uses Hibernate (through the
org.hibernate.Session, not through JPA API) so I have to package
Hibernate along with the application (and make it to play well with JTA
and container-managed transactions). So, because of compatibility
reasons, it has to be Hibernate.

Yeah, that's probably the way to go. We'll try something and I'll post
here later.

Hi Marin,
I think it wouldn't change much as far as the issue's concerned.

Could you describe how you use hibernate and openejb together. It's a
standalone application that uses openejb embedded or...that's the
missing puzzle to me to fully understand the scenario. If you could
send the entire app here, it'd be even better (provided it's not a
huge app).

I'm not. OpenEJB 3 uses OpenJPA underneath and although it's
technically possible to run with other JPA provider noone I heard of
have tried it.

I'd go for removing the older asm library in hibernate, but it's a
shot in the dark that might not bring anything workable.

Repackaging ASM (was: Fwd: OpenEJB and Hibernate)
Posted by David Blevins <da...@visi.com>.
Looks like Martin got passed the ASM issues for Hibernate use, but we
should definitely get our ASM usage repackaged so no one else has to
go to so much hassle.
I'll try to look into this (still catching up on email).

JPA has a design very similar to Hibernate, and you can bundle a JPA
implementation, such as OpenJPA, with your application. As long as
you are on Java5+ in WepSphere, OpenJPA should run fine. Of course,
your application is already written so, I doubt you'll want to switch
to JPA right now.

Thanks for your concern! ;) Our legacy application is using Hibernate as
the persistence provider - JEE Entity Beans are not used at all. So we
had to embed Hibernate into our EAR and deploy it on target AS. BMP is a
valid option but we wanted CMP (descriptive transactions). So, if you
are building normal JEE application with entity beans or JPA you'll
probably never need to embed Hibernate.

Where is Hibernate being used? Is it part of MDB or SLSB? Is BMP with
Hibernate not an option as far as ejb2.1's concerned? Where would
hibernate help openejb3 to mimic the target websphere 6.1 server?

The project's not that unusual - simply we can't use JPA nor EJB3.0,
because our product will finally be deployed on WebSphere6.1 (without
EJB3.0 patches). OpenEJB is a great platform for development of J2EE
application - we are trying simply to get a rapid development of JEE
application on Eclipse. So, the only really interesting point is: how
one can integrate Hibernate (or JPA Hibernate aspect) with CMP on
OpenEJB. I can put up a small example of EJB2.1 application (a single
stateless bean and a mdb bean, plus a Hibernate bean) if you are
interested though.

Just write some major points and we try to figure it out ourselves if
you're swamped with other tasks. It's such an unsual example that only
if I see this as an fully working application I'd be able to get the

Awesome. I wouldn't imagine such stuff is possible in/with OpenEJB.
Even after so long with openejb I can learn new stuff. It'd be great
if you could share the app or better yet write a doc how to work with
hibernate and openejb together. Would you mind? ;-)

Okay, it's java:comp/TransactionManager from within a bean, or
java:openejb/TransactionManager from outside a bean ;) We are using
Hibernate via the JPA interface as follows:
package com.whitestein.fe.impl.config;
import org.hibernate.transaction.JNDITransactionManagerLookup;
/**
* Hibernate Transaction manager lookup strategy for OpenEJB.
*
* @author mvy
*/
public class OpenEJBTransactionManagerLookup extends
JNDITransactionManagerLookup {
@Override
protected String getName() {
return "java:comp/TransactionManager"; //$NON-NLS-1$
}
public String getUserTransactionName() {
return "java:comp/UserTransaction"; //$NON-NLS-1$
}
}
properties.put(Environment.DIALECT, dbDialect);
properties.put(Environment.TRANSACTION_MANAGER_STRATEGY,
OpenEJBTransactionManagerLookup.class.getName());
properties.put(Environment.TRANSACTION_STRATEGY,
CMTTransactionFactory.class.getName());
properties.put(Environment.JNDI_CLASS,
"org.apache.openejb.client.LocalInitialContextFactory");
entityManagerFactory = Persistence.createEntityManagerFactory(
persistenceUnitName, properties);
This way, Hibernate joins the container transactions.

Awesome! I have read about jarjar, but it appears I misunderstood its
purpose. Now, it's clearer.

That's what I can't understand - what jar are you thinking about?

I wouldn't try to modify either; I'd repackage. Most projects seem
to repackage asm to avoid such conflicts, and I'd guess they do it
because Hibernate is not repackaging :)
The ASM FAQ suggests (http://asm.objectweb.org/doc/faq.html) jarjar.
If you can figure out how to do this, that would be awesome. We can
simply add the repackaged jar to our svn repository.
