Loading XMI files in Eclipse Indigo [message #854377]

Hi, everybody.

I'm trying to load XMI files in order to create and XMI that is made out of Ecore elements of some xxx.ecore model. I cannot do it through ATL as M2M because ATL won't let me import as IN parameters arbitrary XMI files (one discovered by MoDisco and another exported by Enterprise Architect).

When I try to load an ecore file in EMF it gives null pointer or tells me some epackage is not registered.

ResourceSet resourceSet = new ResourceSetImpl();
		Resource rs = resourceSet.createResource(URI.createFileURI(file.getAbsolutePath()));
		System.out.println("rs: " + rs);
		//ResourceSet resourceSet = new ResourceSetImpl();

		EPackage.Registry reg1;
		reg1 = resourceSet.getPackageRegistry();
		System.out.println("registry: " + reg1);
		System.out.println("EcorePackage.eNS_URI: " + EcorePackage.eNS_URI);
		System.out.println("EcorePackage.eINSTANCE: " + URI.createFileURI("c:/Users/USUARIO/workspace/archivol/archivol.ecore"));
		reg1.put(EcorePackage.eNS_URI, URI.createFileURI("c:/Users/USUARIO/workspace/archivol/archivol.ecore"));

Rs is always null.

What is it that I'm doing wrong??

Thank you!

Have you generated the model for this?

When running stand alone, you need to register a resource factory.
Like EcoreResourceFactoryImpl for "ecore" extension or
XMIResourceFactoryImpl for extensions of files containing XMI
instances.

Resource rs =
resourceSet.createResource(URI.createFileURI(file.getAbsolutePath()));
 
 System.out.println("rs: " + rs);
 
 //ResourceSet resourceSet = new ResourceSetImpl();
 
 
 EPackage.Registry reg1;
 
 reg1 = resourceSet.getPackageRegistry();
 
 System.out.println("registry: " + reg1);
 
 System.out.println("EcorePackage.eNS_URI: " +
EcorePackage.eNS_URI);
 
 System.out.println("EcorePackage.eINSTANCE: " +
URI.createFileURI("c:/Users/USUARIO/workspace/archivol/archivol.ecore")); 
 reg1.put(EcorePackage.eNS_URI,
URI.createFileURI("c:/Users/USUARIO/workspace/archivol/archivol.ecore"));

The value of a registry's map should be the EPackage instance. If
you really want to do this with a dynamic model rather then
generating code for archivol.ecore you should read:

I use such a code fr EMF:

EPackage.Registry.INSTANCE.put(CreConfigDirPackage.eNS_URI, CreConfigDirPackage.eINSTANCE);
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xml",new CreConfigDirResourceFactoryImpl());

ResourceSet rs = new ResourceSetImpl();
rs.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xml", new CreConfigDirResourceFactoryImpl());
String sFile = "c:\\Users\\Olaf\\ORGA\\Java\\DeployToDatabase\\cre\\config.dir.xml";
URI resourceURI = URI.createURI("file:/" + sFile);
XMLResourceImpl res = (XMLResourceImpl) rs.createResource(resourceURI);

HashMap options = new HashMap();
options.put("LAX_FEATURE_PROCESSING", Boolean.TRUE);

//open Stream
m_pFIS = new FileInputStream(sFile);
//load xml
res.load(m_pFIS, options);
// close stream
m_pFIS.close();

CreConfigDir.DocumentRoot rootCCD = (CreConfigDir.DocumentRoot) res.getContents().get(0);
ListType list = rootCCD.getList();
EList<FileType>eList=list.getFile();

Better to use URI.createFileURI because this approach doesn't convert \
to / and \ isn't a segment separator in a URI so you're likely to have
problems with any relative cross document references.

It's also much easier to use rs.getResource(resourceURI, true) than
doing all these manual steps. You can put default options in
rs.getLoadOptions().
