Overview
The first step in creating a JPA-JAXB meet-in-the-middle solution is to enable EclipseLink OXM to use Dynamic Persistence, a.k.a. processing Projects, Mappings & Descriptors without having concrete Java classes available. This work builds off of the initial Dynamic Persistence functionality (org.eclipse.persistence.dynamic) current used by the JPA component. By supplying a DynamicClassLoader and loading the EclipseLink project by way of DynamicTypeBuilder.loadDynamicProject(), we can inject Dynamic Persistence functionality into EclipseLink OXM in a fairly transparent way.
