Hello,

I'm trying to execute a QVTo transformation using Java where I have 2 xmi files as an input and another xmi file as an output.

My problem is how to define 2 input xmi files? and how to register the xmi package?

For example, If I'm registering UML, I should use this line of code:
resourceSet.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);


What about XMI?

Here is the full code that I currently have:
Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
		Map<String, Object> m = reg.getExtensionToFactoryMap();
		m.put("http://www.eclipse.org/emf/2002/XMI", new XMIResourceFactoryImpl());
		ExecutionContextImpl context= new ExecutionContextImpl();
		context.setConfigProperty("keepModeling", true);
		URI transformationURI = URI.createURI("file:///C:/Users/sama.elrawy/EclipsJEEworkspace/Multi_project/transforms/multi_generation.qvto");
		TransformationExecutor executor = new TransformationExecutor(transformationURI);
		ResourceSet resourceSet = new ResourceSetImpl();

		resourceSet.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
	
		resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("*", new XMIResourceFactoryImpl());
		Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("*", new XMIResourceFactoryImpl());
		Resource inResource = resourceSet.getResource(URI.createURI("file:///C:/Users/sama.elrawy/EclipsJEEworkspace/Multi_project/models/input1.xmi"), true);		
		EList<EObject> inObjects = inResource.getContents();
		ModelExtent input = new BasicModelExtent(inObjects);		
		ModelExtent output = new BasicModelExtent();
		ExecutionDiagnostic result = executor.execute(context, input, output);

		if(result.getSeverity() == Diagnostic.OK) {
			List<EObject> outObjects = output.getContents();
		        ResourceSet resourceSet2 = new ResourceSetImpl();
			Resource outResource = resourceSet2.getResource(
			URI.createURI("file:///C:/Users/sama.elrawy/EclipsJEEworkspace/Multi_project/models/output.xmi"), true);
			outResource.getContents().addAll(outObjects);
			outResource.save(Collections.emptyMap());
		}

Sama,

It's best to ask about QVTo on the eclipse.qvto forum.
