Just to clarify, I'm using Spring to load up my persistence layer, and
my persistence.xml is
<persistence-unit name="main">
<provider>org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider</
provider>
<properties>
<property name="datanucleus.NontransactionalRead"
value="true"/>
<property name="datanucleus.NontransactionalWrite"
value="true"/>
<property name="datanucleus.ConnectionURL"
value="appengine"/>
</properties>
</persistence-unit>
which means it is DataNucleus that is providing my
EntityManagerFactory and hence EntityManager, so any JPA Queries that
get created from this should default to JPQL syntax. No?
thanks,
dave
