I got further yesterday (after removing the ---PlaceHolderDSForOGM--- property from HibernateOgmPersistence). Not sure what the long term change is (perhaps we should only add the ---PlaceHolderDSForOGM--- for the non-container case).

http://pastie.org/4891549 is the out from running one of the example applications (jboss-javaee6-webapp). Obviously, I need to try a different test. ;)

For AS documentation, I'm not sure if we are ready to add that yet (it would be experimental with the goal of helping someone get started). I'm open to suggestions but I think we could build on what I blogged about last year here http://in.relation.to/Bloggers/UsingADifferentPersistenceProviderWithAS70.... - How to add the OGM module to AS - Changing existing AS module dependencies for OGM - Infinispan Configuration changes for OGM - Example

We should either create a blog update to explain this or as previously discussed on this thread, document the changes needed. http://pastie.org/4891854 is my current persistence.xml that I'm testing with. I had to set jboss.as.jpa.adapterModule to org.jboss.as.jpa.hibernate:4, so that we would use the Hibernate 4 integration code with OGM. I also had to set jboss.as.jpa.classtransformer to false so that we wouldn't try to create the EntityManagerFactory too soon (should probably verify if that is still needed). > > I would expect to not have any OGM-specific code in the AS, but that > it should be good enough to implement the JPA spec correctly regarding > the provider implementation? I sometimes hear that question (why don't you just use the JPA spec bootstrapping). However, we are allowed by the JPA specification, to pass a map of integration properties when calling the PersistenceProvider.createContainerEntityManagerFactory(PersistenceUnitInfo, Map integrationProperties) call. Sometimes, the persistence providers include enough version specific application server integration code, so that app servers find that its good enough to just call the JPA spec invocation but in practice this breaks when the app servers change too much. For AS7, I created persistence provider adapters that (optionally) contain the extra integration code that is not handled by the JPA specification. For AS 8.0, I want to change the relationship between the persistence provider adapters and providers to be less tightly coupled (its currently a 1-1) but they make developing JPA applications for AS7 easier for the developer (fewer properties have to be passed in). > >> >> http://pastie.org/4891549 is the out from running one of the example >> applications (jboss-javaee6-webapp).

The jboss-deployment-structure.xml allows you to specify what is or isn't on the deployment classpath but the classpath is not set early enough to be helpful when bootstrapping the persistence unit definitions in the persistence.xml.

I'm still not understanding why we need to hardcode a constant module name for the OGM provider, that's unintuitive and brought me a lot of pain when trying to use a *different* version, when recently trying out your instructions. I might want to deploy OGM using a different version of Hibernate ORM than what I have in another OGM-using application; also it is very likely that soon OGM will require a version which is not the one bundled in the AS. I would expect the module to be something I can configure in my own application: https://github.com/Sanne/ogm-kitchensink/blob/as711/src/main/webapp/WEB-I... it should be possible to use a different module name, how could I deal with multiple deployments otherwise?

I didn't need any datasource, this worked fine: https://github.com/Sanne/ogm-kitchensink/blob/as711/src/main/resources/ME...

You don't have to build it but having it in the cache woud help :) The test is building and materializing an AS7 module on the filesystem containing all dependencies, including Hibernate Search (among others) and uses ShrinkWrap to do that; if you look in the test you should find a line which forces it to stay offline (as it was massively slow otherwise), you should comment that line at least once so that it downloads all what it needs.

A few different ways that we could proceed. In the OGM project, we could assemble an AS7 module that is ready to drop into the AS7 root folder. This wouldn't include the OGM integration code module (which we haven't needed to write but could to make it easier to use OGM with AS7). Another way, would be to start a new project that packages the OGM provider into a ready to use AS7 module.

That may have changed but this place holder was mandatory to get OGM to start in some environment. At least make sure that these change does not break the SE mode.

The placeholder is there because otherwise, some part of Hibernate EntityManager's configuration bootstrap complain. But this value should never be used because Hibernate OGM has an integrator that overrides the ConnectionProviderInitiator with a Noop version. The fact that Sergio's stacktrace shows Caused by: org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [---PlaceHolderDSForOGM---] at org.hibernate.service.jndi.internal.JndiServiceImpl.locate(JndiServiceImpl.java:68) at org.hibernate.service.jdbc.connections.internal.DatasourceConnectionProviderImpl.configure(DatasourceConnectionProviderImpl.java:116) is proof to me that the OgmIntegrator is not taken into account which means that the file META-INF/services/org.hibernate.integrator.spi.Integrator is not seen by Hibernate ORM when it bootstraps the application which means that Hibernate OGM's classpath is not visible where it should be.

That's why I strongly suspects that this is either a JBoss modules bug or some misconfiguration of the ogm modules. We could try and give a better error report, open an issue for that but at the end of the day, something is broken in the ORM-AS integration wrt integrator and service discovery. Emmanuel
