Dear all,
I'm new in using EMF. I'm trying to validate and XMI againts an ecore model. In eclipse interface I succeed to import them and validate. I'm trying to do the same calling the validation via java.

To load my XMI and ecore file I'm doing:

private static ResourceSet rs = new ResourceSetImpl();
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("ecore", new EcoreResourceFactoryImpl());
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xmi", new XMIResourceFactoryImpl());
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xml", new XMLResourceFactoryImpl());
EcorePackage ecorePackage = EcorePackage.eINSTANCE;
URI my_file = createFileURI(my_ecore.getAbsolutePath());
Resource r = rs.getResource(my_file, true);
if(eObject instanceof EPackage){
EPackage p = (EPackage) eObject;

URI uri = createFileURI(my_xmi.getAbsolutePath());
Resource resource;
resource = Resource.Factory.Registry.INSTANCE.getFactory(uri).createResource(uri);

When I'm loading the xmi I have something like:

org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Class 'DataSet' is not found or is abstract.

Any idea?
Thank you
Best Regards

What file extension does your resource use, xmi I assume? What does the start of the XML/XMI look like? Don't you have a generated model? If you do, try Generate Test Code and look for the to see how to load your model.
