Hello,
I'm having the same problem as Chris and Oliver. I have read both threads
hoping to implement some of the suggestion from Ed Merks. Here is the code I
am having problems with:
try {
URI fileURI = URI.createFileURI(xmlFile);
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put
(Resource.Factory.Registry.DEFAULT_EXTENSION, new
Ei2dResourceFactoryImpl());
Resource res = resourceSet.getResource(fileURI, true);
DocumentRootImpl root = (DocumentRootImpl)res.getContents().get(0);
return root;
}
I've tried the following:
try {
URI fileURI = URI.createFileURI(xmlFile);
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getPackageRegistry().put(null, Ei2dPackage.eINSTANCE);
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put
(Resource.Factory.Registry.DEFAULT_EXTENSION, new
Ei2dResourceFactoryImpl());
Resource res = resourceSet.getResource(fileURI, true);
DocumentRootImpl root = (DocumentRootImpl)res.getContents().get(0);
return root;
}
not the error is:
Caused by: org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature
'ei2dImpl' not found. (file:/C:/qs_dir/qs_xml_26.xml, 1, 30)
I've tried Eric's Solution:
Resource res = resourceSet.createResource(fileURI);
You'll have to excuse my ignorance here, as I am new to using EMF and I'm
not quite sure how to use the resourceSet.load method. I checked in the
Ei2dResourceFactoryImpl class, and I don't see:
public Ei2dResourceFacotryImpl () {
super();
extendedMetaData = new new BasicExtendedMetaData(new
EPackageRegistryImpl(EPackage.Registry.INSTANCE));
extendedMetaData.putPackage(null, Ei2dPackage.eINSTANCE);
}
Is there a way I can just add an equivalent to my class to get things
working?
Thanks in advance,
Jerome

Does your EidResourceFactoryImpl register the package in this way.
I.e., is it really a null namespace package with extended metadata on it
as for a schema with no target namespace:
XML Schema to Ecore Mapping

It would help to see more of your model and the file instance.

It sounds like probably you don't really have a null namespace schema
(or a model annotated like one). How did you define your model? Can
you show the file you are trying to load?

For each Impl class there is a corresponding interface where the later
is what your clients should be using directly. Although not
specifically an issue for a document root, EMF supports multiple
inheritance so you might have C and extends both A and B but CImpl will
only extend either AImpl or BImpl so assuming that B can always be cast
to BImpl is not a save assumption. You should treat model impl classes
as something you only access directly if you need to extend that class.

That makes me things it's not really a null namespace package and so if
you register as if it is, you might find that global elements from that
package still want to be using the namespace of that package. That's
what it looks like to me.

Jerome,
If you generate a model for a schema without a target namespace you'll
see that the EPackage's extended meta data EAnnotation has a
"qualified"->"false" mapping. It sounds like this is missing. from
your model.

You'll have to excuse my ignorance here, as I am new to using EMF and =
I'm=20
not quite sure how to use the resourceSet.load method. I checked in the=20
Ei2dResourceFactoryImpl class, and I don't see:
public Ei2dResourceFacotryImpl () {
super();
extendedMetaData =3D new new BasicExtendedMetaData(new=20
EPackageRegistryImpl(EPackage.Registry.INSTANCE));
extendedMetaData.putPackage(null, Ei2dPackage.eINSTANCE);
}
Is there a way I can just add an equivalent to my class to get things=20
working?
It sounds like probably you don't really have a null namespace schema =
(or a model annotated like one). How did you define your model? Can =
you show the file you are trying to load?
I have attached the file with I am trying to process.=20
Thanks for your help,
Jerome
Thanks in advance,

<DIV>For each Impl class there is a corresponding interface where =

only extend either AImpl or BImpl so assuming that B can always be =

BImpl is not a save assumption. You should treat model impl =
