Hi, 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). Is there something I missed? (I'm using openjpa 2.11) Best regards Marcel -- RSC Commercial Services GmbH & Co.
