WildFly 8, JPA 2.1: HowTo?

[lafr]

After upgrading to latest sources including the update to JPA 2.1 I get this error:

I already updated my pesistence.xml to

{code:xml}
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
        version="2.1">
</persistence>
{code:xml}

but this did not help.

What am I missing?

Frank,

In your persistence.xml, try commenting out the provider class name or use the new Hibernate 4.3.x class name org.hibernate.jpa.HibernatePersistenceProvider.

Just added a note about this change to https://docs.jboss.org/author/display/WFLY8/JPA+Reference+Guide#JPAReferenceGuide-UpdateyourPersistence.xmlforHibernate4.3.0.

[andy.miller]

Scott, why did this change.  This is a breaking backward compatibility change, but this is only a major.minor release of Hibernate (4.2.x vs. 4.3.x).  That violates our own rules for backward compatibility.

[smarlow]

Andy,

I missed your question before.  Hibernate 4.3.x was later changed to allow the deprecated provider class name (org.hibernate.ejb.HibernatePersistence) to be used.

Okay, thanks Scott.  That makes me feel much better!
