Use of pre-existing EclipseLink ORM and MOXy 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 the following naming convention:
- 1. identical case-sensitive Project names
<xml version="1.0" encoding="UTF-8"?> <object-persistence version="Eclipse Persistence Services - @VERSION@ (Build @BUILD_NUMBER@)" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.eclipse.org/eclipselink/xsds/persistence" > <name>Example</name>
import org.eclipse.persistence.sessions.Project; public class SomeORProject extends Project { public SomeORProject () { setName("Example"); ... } public class SomeOXProject extends Project { public SomeOXProject () { setName("Example"); ... }
- 2. identical case-sensitive aliases for Descriptors that are common between the projects
<class-mapping-descriptor xsi:type="relational-class-mapping-descriptor"> <class>some.package.SomeClass</class> <alias>SomeAlias</alias> ... <class-mapping-descriptor xsi:type="xml-class-mapping-descriptor"> <class>some.package.SomeClass</class> <alias>SomeAlias</alias>
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.
