Use Hibernate as a persistence provider with Glassfish

As you must be aware, Glassfish currently has Toplink Essentials as the default persistence provider. The question that frequently gets asked is: How hard it is to to use hibernate as the persistence provider with Glassfish?
The answer is:  Not at all :). Just drop couple of jars reqired by hibernate in the lib directory of Glassfish and modify your persistence.xml to use hibernate as the provider and you are ready to go. Lets walk through the steps:

1. Download and install glassfish milestone 6 build or later.
2. Download and install Hibernate3 3.2cr1 or later.
3. Download and install Hibernate EntityManager 3.1 beta7 or later.
4. Copy the required hibernate jars into Glassfish lib dir. The script here contains the list of jars.
5. Update your persistence.xml to use hibernate as the persistence provider. Here is a sample persistence.xml
6. Deploy and run your application.

If you're using Spring 2.0 what is the databasePlatform? It was oracle.toplink.essentials.platform.database.MySQL4Platform What is the hibernate equivalent? <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="showSql" value="true" /> <property name="generateDdl" value="true" /> <property name="databasePlatform" value="" /> </bean>

Please note that Hibernate is not able to deal with spaces in the full path to deployed application. If you plan to use Hibernate as the persistence provider inside Glassfish, please make sure that the Glassfish installation path does not contain spaces. Please see Glassfish discussion forum threadfor more discussion on this

The script that Mitesh provides copies hibernate-annotations.jar from hibernate-entitymanager/lib dir. This may not always work. One needs to use compatible version of Hibernate Annotations(http://hibernate.org/247.html). See http://forums.java.net/jive/thread.jspa?threadID=16875&tstart=0 -- Sahoo

Also note that this doesn't seem to work with Hibernate core 3.2.0-cr4, you have to downgrade to hibernate 3.2.0-cr2. It seems to work with annotations and entity manager versions 3.2.0-cr1

Hello! I just tried that with Hibernate 3.2.1-GA and hibernate entity manager 3.2.1-GA. I'm using PostgreSQL and sequences in it for primary key generation. Now I'm getting an error "org.hibernate.AnnotationException: Unknown Id.generator" on it. Do you know what it may be or how to fix it ?

No go. I am getting an exception with the method described:

com.sun.enterprise.deployment.backend.IASDeploymentException: Could not resolve a persistence unit corresponding to the persistence-context-ref-name [mypackage.MyClass/myPU] in the scope of the module called [].

To this day I haven't been successful getting any persistence framework to run with Glassfish with the exception of the provided Toplink, which is extremely slow.

Got rid of the above error, got the newest, compatible annotation jars, now I have this:

java.lang.NoClassDefFoundError: javax/transaction/SystemException

Hi all,

Thanks a lot, your description helped me a lot. I just did it. It took me something like 30 minutes (something that can help is watching out the compat' matrix to put compatible HEM, H3 and HA jars together: http://www.hibernate.org/6.html#A3)

Is there a way to change the default provider?
I mean: be able to use Hibernate as the default persistence provider without specifying <provider>org.hibernate.ejb.HibernatePersistence</provider>?

I'm going to have a look at it, so if someone already did it, I'd be delighted to have some insights :).

Cheers.

Hi,
We are using JPA with Hibernate and Glassfish 9.0.
Hibernate log all debug and Info.We dont want all the things. How to configure the logging level of hibernate properties in glassfish.

Posted by Sankar on September 02, 2008 at 07:11 PM PDT #

Hi Sanakar,

Hibernate uses log4j as its logging framework. Please refer to Hibernate documentation to configure logging level.

Thanks,
