Hibernate OGM on AS7

[milenkovic.m]

Hi guys,

have anyone managed to bootstrap Hibernate OGM on AS7? Looks like that documentation that explains required configuration is outdated.

Currently, AS 7.0.0 throws a NPE if you try to deploy persistence.xml with HibernateOgmPersistence provider. From the log file I can't find the root of the problem. However, if you try to deploy the same application on AS nightly snapshot, a bit "better" exception is thrown

Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: only one persistence provider can be packaged with an application [org.hibernate.ogm.jpa.HibernateOgmPersistence, org.hibernate.ejb.HibernatePersistence]

if I try to remove hibernate-entitymanager dependencies it starts to complain about missing classes provided by hibernate-entitymanager.

Is there some configuration option that I miss ?

best regards

AS 7 currently does not know how to deploy alternative JPA provider and Hibernate OGM is one.

Scott is looking at this.

Marko, are you building AS7 from source?  I put a patch together (https://github.com/jbossas/jboss-as/pull/138) that should get pulled into either AS 7.0.1 or 7.1.  The patch should address the deployment exception.  If your building from AS7 source, I can point out the (git) commits that you would need to cherry-pick.

no i got it from nightly build ( hudson )

The needed AS7 changes were merged into the AS7 master git repository last night.

Some success today with  the latest OGM (you will need Sanne's OGM fix from today).  I created an as7/modules/org/hibernate/ogm folder with the hibernate-ogm-core-3.0.0-SNAPSHOT.jar and module.xml (see http://pastie.org/2353169 for the contents).  I also created an as7/modules/org/hibernate/3 folder as is already known how to do (https://docs.jboss.org/author/display/AS7/JPA+Reference+Guide).

The test case is very simple and is run after manually applying the above changes to a freshly built AS7.  https://github.com/scottmarlow/jboss-as/blob/ogm/testsuite/compat/src/test/java/org/jboss/as/testsuite/compat/jpa/hibernate/OGMHibernate3SharedModuleProviderTestCase.java

I ran the test and captured the server.log output here http://pastie.org/2353229.  Not much to see but could be interesting for comparing to what you see in your server.log.

I have one app using cassandra as database.

It worked with JBoss AS 7.0.0, but i tried  7.0.2 and:

Any tips?

Can you try the nightly build (the above error should now be fixed)?  Link is community.jboss.org/thread/167590

Jira AS7-2046 represents this issue.  I was wrong about it being fixed already.  The workaround is to package the desired provider as a module. 

[menegazzo]

Sorry, i didnt have enough time to test, but as your last post says, i will need to create a module and configure it under standalone-preview.xml, right?

[smarlow]

If your trying trying to use OpenJPA, watch thread http://community.jboss.org/thread/173967 to learn more about the community effort to integrate that.
