Hi,
I want to use a xmi file content throught a java structure. To do this, i
use EMF.
I have generated XMI and UML java classes from UML2XMI.xsd using EMF
internal ecore model.
I have created a short program to test this java structure whose main
method is :
public static void main(String[] args) {
ResourceSet resourceSet = new ResourceSetImpl();
final ExtendedMetaData extendedMetaData = new BasicExtendedMetaData(
resourceSet.getPackageRegistry());
resourceSet.getLoadOptions().put(XMLResource.OPTION_EXTENDED _META_DATA,
extendedMetaData);
resourceSet.getPackageRegistry().put("xmi", XmiPackage.eINSTANCE);
resourceSet.getPackageRegistry().put("uml", UmlPackage.eINSTANCE);
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap()
.put("xmi", new XmiResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap()
.put("uml", new UmlResourceFactoryImpl());
URI fileURI = URI.createFileURI(new File(
"resources/diagram.xmi").getAbsolutePath());
Resource resource = resourceSet.getResource(fileURI, true);
System.out.println("ok");
}
Here, first lines of XMI file :
<?xml version="1.0" encoding="UTF-8"?>

During main method execution, an exception is thrown :

I defined a Resource Factories, one for xmi markups another for uml
markups however parser does not recognize <uml:Activity> markup.
Can anyone explain to me where i make a mistake ?

Gross. That sound horrible. XMI schemas are terrible things that don't
properly describe structure. The UML model is already generated so
you'd use that for processing UML instances.

This sounds like completely the wrong approach. The UML model and GMF
provide model implementations already, along with resource factories set
up to process these types of XMI files, so you should be using those
directly, not trying to reconstruct some type of analog from the XMI
Schema representation for them.
