Problems when using "openjpa.MetaDataFactory" Property
------------------------------------------------------
Key: OPENJPA-2040
URL: https://issues.apache.org/jira/browse/OPENJPA-2040
Project: OpenJPA
Issue Type: Bug
Affects Versions: 2.1.1
Reporter: Marcel Urbanek
I want to overwrite the MetaDataFactory like described here:
http://openjpa.apache.org/builds/1.0.2/apache-openjpa-1.0.2/docs/manual/ref_guide_meta.html
But it turned out it doesn't work. I managed to develop a test scenario
which easily produces the behaviour I encountered.
What _does_ work is the following:
Adding
<property name="openjpa.MetaDataFactory" value="jpa"/>
to persistence.xml.
When setting this property my junit test (persisting a simple association,
using @Column Annotation to use differing column names) does work.
According to the document above, this property Tag should be equivalent to
the setting above:
<property name="openjpa.MetaDataFactory"
value="org.apache.openjpa.persistence.PersistenceMetaDataFactory"/>
But when using this configuration my junit test fails. The differing
Column Names set by the @Column.name Attribute are no longer found.
Instead the Java Attribute-Names are used in the SQL.
My problem is, that I want to implement a custom MetaDataFactory and this
doesn't work either (which is expected, because I extend
PersistenceMetaDataFactory).
Using PersistenceMappingFactory instead doesn't work either.
