/**
* Reads purchase order DataObject from XML, based upon Fuhwei Lwo's paper Create and read an XML document based on XML
* Schema. Uses file
* {@link org.apache.tuscany.samples.sdo.SdoSampleConstants#PO_XML_GENERATED}
* previously generated by {@link CreatePurchaseOrder} to populate purchase order
* DataObject
*
* Usage:
* This sample can easily be run from within Eclipse as a Java Application if tuscany or
* the sample-sdo project is imported into Eclipse as an existing project.
*
* If executing as a standalone application please do the following:
*
*
* - Include the following jar files on your classpath :
*
* - SDO API and Tuscany Implementation
*
* - sdo-api-{version}.jar - SDO API
*
- tuscany-sdo-impl-{version}.jar - Tuscany SDO implementation
*
*
* - EMF dependencies.
*
* - emf-common-{version}.jar - some common framework utility and base classes
*
- emf-ecore-{version}.jar - the EMF core runtime implementation classes (the Ecore metamodel)
*
- emf-ecore-change-{version}.jar - the EMF change recorder and framework
*
- emf-ecore-xmi-{version}.jar - EMF's default XML (and XMI) serializer and loader
*
- xsd-{version}.jar - the XML Schema model
*
*
*
*
* These jar files can be obtained from directly from Tuscany and EMF projects or from SDO Execution Dependancies
* - Execute:
* java org.apache.tuscany.samples.sdo.otherSources.ReadPurchaseOrder
