Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put("ecore",EcoreResourceFactoryImpl)
val classLoader = kl.classLoader
System.out.println(System.getProperty("user.dir"));
val resource = (classLoader).getResource("/model/extlibrary.ecore")
var ff = URI.createFileURI(System.getProperty("user.dir")+"/model/extlibrary.ecore");

var URI ecoreFileURI = ff
var URI ecoreModelURI = ecoreFileURI.appendFragment("/"); //$NON-NLS-1$

var ResourceSet resourceSet = new ResourceSetImpl();
var res = resourceSet.getResource(ecoreModelURI,true)
var f = resourceSet.getEObject(ecoreModelURI, true)
println(f)


this gives me class cast Exception

Hello,

I think you are registering a Class in the Resource.Factory.Registry, you should try to register an instance of ResourceFactory, like this : 

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put("ecore", new EcoreResourceFactoryImpl())
