Hi, I'm getting a

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'Model' not found.

when I try to compare 2 xmi files with Emf Compare.

I'm kind of a beginner with this but I'm having a lot of trouble trying to fix this issue. Here's the code :


public static void compare() {

EPackage.Registry.INSTANCE.put(UmlPackage.eINSTANCE.getNsURI(), UmlPackage.eINSTANCE);


// Load the two input models
ResourceSet resourceSet1 = new ResourceSetImpl();
ResourceSet resourceSet2 = new ResourceSetImpl();
URI uri = URI.createFileURI(new File("xmi/test1.xmi").getAbsolutePath());
URI uri2 = URI.createFileURI(new File("xmi/test2.xmi").getAbsolutePath());

resourceSet1.getPackageRegistry().put(UmlPackage.eINSTANCE.getNsURI(), UmlPackage.eINSTANCE);
resourceSet2.getPackageRegistry().put(UmlPackage.eINSTANCE.getNsURI(), UmlPackage.eINSTANCE);
resourceSet1.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xmi", new XmiResourceFactoryImpl());
resourceSet2.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xmi", new XmiResourceFactoryImpl());


resourceSet1.getResource(uri, true);
resourceSet2.getResource(uri, true);


// Configure EMF Compare
IEObjectMatcher matcher = DefaultMatchEngine.createDefaultEObjectMatcher(UseIdentifiers.NEVER);
IComparisonFactory comparisonFactory = new DefaultComparisonFactory(new DefaultEqualityHelperFactory());
IMatchEngine.Factory matchEngineFactory = new MatchEngineFactoryImpl(matcher, comparisonFactory);
matchEngineFactory.setRanking(20);
IMatchEngine.Factory.Registry matchEngineRegistry = new MatchEngineFactoryRegistryImpl();
matchEngineRegistry.add(matchEngineFactory);
EMFCompare comparator = EMFCompare.builder().setMatchEngineFactoryRegistry(matchEngineRegistry).build();

// Compare the two models
IComparisonScope scope = EMFCompare.createDefaultScope(resourceSet1, resourceSet2);


ICompareEditingDomain editingDomain = EMFCompareEditingDomain.create(resourceSet1, resourceSet2, null);
AdapterFactory adapterFactory = new ComposedAdapterFactory(ComposedAdapterFactory.Descriptor.Registry.INSTANCE);
@SuppressWarnings("restriction")
CompareEditorInput input = new ComparisonScopeEditorInput(new CompareConfiguration(),
editingDomain, adapterFactory, comparator, scope);

CompareUI.openCompareDialog(input);

}



and the exception :

EMF provides XMIResourceFactoryImpl so what is XmiResourceFactoryImpl?

It's impossible to comment on why your unknown-to-me serialization
doesn't conform to your unknown-to-me model. Can you read and write
instance of your model with the generated editor?

Thanks but I'm gonna need some more help, because I'm really new to EMF and I don't have any idea how to do this :/

Pey,

Is this your own model you've developed yourself? Where did the
serialization you're trying to load come from?

Well I'm working on a project that was created by 4 students two years ago and they developed the model themselves. And the serialization is just something I found on the web.

Pey,

The serialization must correspond to a model, so if that's not the case
(which sounds like it), then you'll not be able to load it.

What do you mean by "serialization" ?

Pey,

You said "And the serialization is just something I found on the web."
What do you mean by "serialization"? I assumed you meant the XML/XMI
file you're trying to read; it must correspond to a model, e.g., this
UmlPackage model you seem to be using. That appears not to be the case.

Well I actually don't know what is the package for the model I'm using. How do I found out ? I used UmlPackage because I saw a lot of people using it on the web but since the serialization is based on a custom metamodel, I should probably use another ... But I got no idea how to find it.

From the namespace. Top level element(s) in the XMI. There must be an
EPackage with an nsURI that corresponds and then the rest of the
serialization must conform the EClasses defined in that model.

Nor do I.
