Use of pre-existing EclipseLink ORM and OXM mappings

A DBWS service may be constructed using pre-existing EclipseLink ORM and OXM maps (both Project classes and Project deployment XML are supported) with identical case-sensitive aliases for Descriptors that are common between the projects

Any existing named queries from the EclipseLink ORM map may be exposed as query operations for the EclipseLink DBWS service; additional Insert/Update/Delete/Query operations can be added. Pre-existing domain classes can be bundled with the service so that they are available at runtime.
