Using 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.

Example 2-6 Using an ORM Map

<?xml version="1.0" encoding="UTF-8"?>
<object-persistence version="Eclipse Persistence Services - some version (some build date)" xmlns="http://www.eclipse.org/eclipselink/xsds/persistence" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:eclipselink="http://www.eclipse.org/eclipselink/xsds/persistence">
   <name>SomeORProject</name>
   <class-mapping-descriptors>
      <class-mapping-descriptor xsi:type="relational-class-mapping-descriptor">
         <class>some.package.SomeClass</class>
         <alias>SomeAlias</alias>
...
 

Example 2-7 Using an OXM Map

<?xml version="1.0" encoding="UTF-8"?>
<object-persistence version="Eclipse Persistence Services - some version (some build date)" xmlns="http://www.eclipse.org/eclipselink/xsds/persistence" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:eclipselink="http://www.eclipse.org/eclipselink/xsds/persistence">
   <name>SomeOXProject</name>
   <class-mapping-descriptor xsi:type="xml-class-mapping-descriptor">
      <class>some.package.SomeClass</class>
      <alias>SomeAlias</alias>
...
 

When building a DBWS web service in this way (that is, without the DBWSBuilder Utility) be sure to create all the necessary deployment artifacts
