The 1st option you mentioned is `JDOPersistenceManagerFactory.setPersistenceProperties()`, right? The underlying logic of those 2 options seems identical - saving the properties via `Configuration.setPersistenceProperties`, please correct me if I misunderstood.
One thing confusing is that PersistenceUnitMetaData only support String value properties, while overrideProps supports Object value; And when constructing PMF, those 2 properties are actually merged into one Map. So one question is - Is it better to make PersistenceUnitMetaData support Object value?
public JDOPersistenceManagerFactory(PersistenceUnitMetaData pumd, Map overrideProps) { // Build up map of all properties to apply (from persistence-unit + overridden + defaulted) Map props = new HashMap(); if (pumd != null && pumd.getProperties() != null) { props.putAll(pumd.getProperties()); } if (overrideProps != null) { props.putAll(overrideProps); }
