Is anybody aware of an effective way to ensure that the openjpa jars distributed in a WAR are used for the persistence implementation? I have tried
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> in persistence.xml, and javax.persistence.spi.PersistenceProvider=org.apache.openjpa.persistence.PersistenceProviderImpl in the emf properties map but neither appear to work. This problem occurs when deploying to Glassfish, oc4j and (to a lesser extent) Resin (resin provides a buggy ejb30.jar). It seems to be a classloading problem, because these containers load the Persistence.class from their own lib instead of the webapp's. Since that class can't find openjpa, it just falls back to toplink. I had expected the webapp's classes to be loaded in preference to the containers though. Any suggestions?
