Frank Budinsky commented on TUSCANY-112:
----------------------------------------
It sounds like this static initialization in class DataObjectUitl hasn't run in
your environment:
/**
* Configure EMF to support the SDO runtime by registering a specialized
Ecore factory, SDOEcoreFactory.
* This static initializion must run before any SDO metadata is created or
loaded.
* As long as SDO helper classes (e.g., TypeHelper, XMLHelper, etc.) are
accessed though their
* corresponding INSTANCE fields (e.g., TypeHelper.INSTANCE), or using the
SDOUtil methods (e.g.,
* SDOUtil.createTypeHelper(), this will always be the case.
*/
static
{
EPackage.Registry.INSTANCE.put(EcorePackage.eNS_URI, new
EPackage.Descriptor()
{
public EPackage getEPackage()
{
return EcorePackage.eINSTANCE;
}
public EFactory getEFactory()
{
return new SDOFactoryImpl.SDOEcoreFactory();
}
});
}
You can force it by calling DataObjectUtil.initRuntime() in your startup code.
