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.
