Hi Larry, I'm not sure wether I can help you but at least I can explain you how AXgen makes sure the DDL will meet the needs of OJB. Both, the OJB repository.xml and the DDL are generated based on the same UML model (the XMI). The templates make sure that the table definitions in the DDL and the definitions in the OJB mapping use the same types.
I never tried to generate the DDL from the repository directly as we model all of our classes, we never needed such a feature. Modelling entities in a case tool and use this model as input for all generation works very well.
