Hi Rick,
when I use
<property name="openjpa.MetaDataFactory" value="
"org.apache.openjpa.persistence.jdbc.PersistenceMappingFactory(types=com.retail_sc.test.entity.Group;com.retail_sc.test.entity.Person;)"
/>
The same error ("no registered metadata") occurs.
After some investigation (looking at JDBCPersistenceProductDerivation) I
found out that following configuration:
<property name="openjpa.MetaDataFactory" value=
"org.apache.openjpa.persistence.PersistenceMetaDataFactory"/>
<property name="openjpa.jdbc.MappingFactory" value=
"org.apache.openjpa.persistence.jdbc.PersistenceMappingFactory"/>
<property name="openjpa.jdbc.MappingDefaults" value=
"org.apache.openjpa.persistence.jdbc.PersistenceMappingDefaults"/>
Leads to following Exception:
org.apache.openjpa.persistence.ArgumentException: You cannot join
on column "MPTZZY.NA_GRP". It is not managed by a mapping that supports
joins.
which looks a little better to me?
Actually I think the main problem is, that PersistenceProductDerivation
and JDBCPersistenceProductDerivation both are setting the "JPA" Alias.
But one sets MetaDataFactory for Alias JPA whith
PersistenceMetaDataFactory and one sets MetaDataFactory for Alias JPA with
PersistenceMappingFactory. During execution both,
PersistenceProductDerivation and JDBCPersistenceProductDerivation are
invoked which results in MetaDataFactory being set to the one or the other
value, depending on which Derivation was called lately. This is nothing
one could easily configure in the persistence.xml.
Instead I would have to implement an own Derivation? I am a little
confused.
Best regards Marcel

Subject: Re: Problems when using "openjpa.MetaDataFactory" Property
Try specifying your types also --> <property
name="openjpa.MetaDataFactory"
value="org.apache.openjpa.persistence.jdbc.PersistenceMappingFactory(types=com.retail_sc.test.entity.Group;com.retail_sc.test.entity.Group2;...etc/>
This happens at runtime, but I can't find where it happens atm.
