public class PersistentPojoDataSource
extends PojoDataSource

A data source for working with Persistent POJOs. When the application is loaded the datasources are instantiated and in the case of a PojoDataSource the PojoRoot instance specified by the root element is instantiated and configured. The configuration project involves traversing the class hierarchy and setting up PojoModel nodes or proxies for each class in the pojo hierarchy. The configuration can specify naming overrides if the names established by reflection are not suitable
