-------------------------------------
Hi Dan,
Tuscany SDO is currently built on top of the EMF. The scenario is 1 EMF and 1
SDO in the env.
The problem lies who EMF or Tuscany SDO initializes the EcoreFactory eINSTANCE
= org.eclipse.emf.ecore.impl.EcoreFactoryImpl.init(); first. In order for SDO
to work, the implementation of eINSTANCE must be the SDOEcoreFactory class
defined in the SDOFactoryImpl.java. When EMF was init first, the EcoreFactory
eINSTANCE will be EMF's EcoreFactoryImpl and SDO will be broken.
To initialize EMF first, you can modify SimpleDynamicTestCase.setUp() method to
add an extra line - EcoreFactory.eINSTANCE.getEcorePackage(); and everything
would break.
protected void setUp() throws Exception {
super.setUp();
EcoreFactory.eINSTANCE.getEcorePackage();
// Populate the meta data for the test (Stock Quote) model
URL url = getClass().getResource(TEST_MODEL);
InputStream inputStream = url.openStream();
XSDHelper.INSTANCE.define(inputStream, url.toString());
inputStream.close();
}
