Hi,

IŽve a Problem with my XMI import. The following code snipped shows, how
my Import should work:

public static Resource loadXMI(String extension, String path){
//Initialize the UMLMetaModel package
UMLPackageImpl.init();

//create resource set and resource
ResourceSet resourceSet = new ResourceSetImpl();

//Register XML resource factory

resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put(extension,
new XMIResourceFactoryImpl());

//Create a resource
Resource resource = resourceSet.createResource(URI.createFileURI(path));

//Load the resource
try{
resource.load(null);
}catch (IOException e) {
e.printStackTrace();
}
return resource;
}

This import routine works with the following XMI-file:

<?xml version="1.0" encoding="ASCII"?>
<uml:Package xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:uml="http://www.eclipse.org/uml2/2.1.0/UML" name="familyTreePackage">
<packagedElement xsi:type="uml:Class" name="Individual"
isAbstract="true">
<ownedAttribute name="vorname" visibility="private"/>
<ownedAttribute name="nachname"/>
<ownedOperation name="getName"/>
</packagedElement>
<packagedElement xsi:type="uml:Class" name="Male"/>
</uml:Package>

BUT when I try to import another XMI-File (which comes out of my
UML-tool), a exception is thrown:

org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Package with
uri 'null' not found.

You're not going to be able to read UML 1.4 instances nor can EMF
consume XMI 1.x in general.

You'll only generally be able to read XMI 2.0 serializations and even
then, the serialization must conform some existing Ecore model, i.e, for
UML it better be some version of UML 2.x...
