/**
* Demonstrates creating a DataObject from an XML String.
*
* The following sample is from the Apache Tuscany project. It was written to help users
* understand and experiement with SDO. It is based upon example code contained
* within, and is meant for use with, and reference to the SDO Specification. In general this sample attempts to use the
* code and comments contained within the specification, exceptions to this are noted
* in comments.
*
* Specifically this sample is based upon the 'Creating DataObject Trees from XML
* documents' example from the Examples section of the SDO Specification. It is
* possible to convert to and from XML documents to build DataObject trees, which is
* useful when assembling DataObjects from serval data sources. This sample uses the
* XMLHelper to convert xml Strings to DataObjects.
*
* Uses previously defined model
* {@link org.apache.tuscany.samples.sdo.SdoSampleConstants#PO_XSD_RESOURCE} to
* define types then generates a purchase order DataObject and persists to
* {@link org.apache.tuscany.samples.sdo.SdoSampleConstants#PO_XML_GENERATED}
*
* 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 by downloading and unpacking a Tuscany binary distribution
* - Execute:
* java org.apache.tuscany.samples.sdo.specExampleSection.CreatingDataObjectTreesFromXMLDocuments
