[news.eclipse.modeling.mdt.uml2] Re: Generating Java-classes?

[skobilke@xxxxxx ( Usul)]

Thank you for answering Kenn,

but I still dont understand.  I need the Java-classes which represent the 
metamodel.  Are you saying they already exist?  Where can I find them?

What I want to do is to write an eclipse-plugin which can create 
uml-models.  So I need the Java-classes in order to do this:

//  create root of model
umlFac = UmlFactory.eINSTANCE;
Model root = umlFac .createModel();
//  build model
..
// save model
ResourceSet resourceSet = new ResourceSetImpl();
IProject project = selectedFolder.getCorrespondingResource().getProject();
IFolder modelFolder = this.getModelFolder(project);
IFile file = modelFolder.getFile("themodel.uml");
String path = file.getLocation().toFile().getAbsolutePath();
URI fileURI = URI.createFileURI(path);
Resource resource = resourceSet.createResource(fileURI);
resource.getContents().add(root );
system.resource.save(Collections.EMPTY_MAP);
