Unable to load UML model in stand alone application [message #884601]

Hello everybody,

I am really new to the Eclipse UML 2 project and I am trying to load a UML model in my standalone application. To do so I have created a new java project and I have included the following jars

org.eclipse.emf.common_2.7.0.v20120127-1122.jar
org.eclipse.emf.ecore.xmi_2.7.0.v20120127-1122.jar
org.eclipse.emf.ecore_2.7.0.v20120127-1122.jar
org.eclipse.uml2.common_1.6.0.v201105021727.jar
org.eclipse.uml2.uml_3.2.100.v201108110105.jar

Then I have this code trying to load the UML model from the getting started guide saved under C:/ExtendedPO2.uml

public class Main {
	
	public static void main(String[] args){
		String location="c:/ExtendedPO2.uml";
		Model m=load(URI.createFileURI(location));
		System.out.println(m.getQualifiedName());
	}
	
	protected static Model load(URI pathToModel)
	{ 
		ResourceSet set = new ResourceSetImpl();
		set.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
		set.getResourceFactoryRegistry().getExtensionToFactoryMap()
				.put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
		UMLPackage.eINSTANCE.eClass();
		set.createResource(pathToModel);
		Resource r = null;
		r = set.getResource(pathToModel, true);
	 
		Model m = (Model) EcoreUtil.getObjectByType(r.getContents(),
					UMLPackage.Literals.MODEL);
	 
		return m;
	}
}

Unfortunately the loaded model is null and I am not able to print the qualified name.
Can someone please help me understanding what's going on?
Thank you for your help

HI

It looks like your package registrations are wrong, but since you
haven't provided your ExtendedPO2.uml it's difficult to check.

Juno makes this all much easier by providing

ResourceSet set = new ResourceSetImpl();
UMLResourcesUtil.init(set);

Hi

I finally got fed up with answering this generic question. I looked at
http://wiki.eclipse.org/MDT/UML2/Getting_Started_with_UML2; it has a
major howler in it regarding "save" that makes life very hard for new
users. https://bugs.eclipse.org/bugs/show_bug.cgi?id=382342 raised. Wiki
corrected.

There is an attachment to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=382342 that you may
download to give a working example standalone project.

Regards

Ok thank you.
I am not sure on how this was related to my loading problem, as you said probably it was a namespace problem. However this is the code that I have now in place together with the sample .uml file. This one works

import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
import org.eclipse.emf.ecore.util.EcoreUtil;
import org.eclipse.uml2.uml.Model;
import org.eclipse.uml2.uml.UMLPackage;
import org.eclipse.uml2.uml.resource.UMLResource;


public class Main {
	
	private URI typesUri = null;
	
	public static void main(String[] args){
		Model m=new Main().getModel("C:/mylocalpathto/ExtendedPO2.uml");
		System.out.println(m.getName());
	}
	
	public Model getModel(String pathToModel) {
		
		typesUri = URI.createFileURI(pathToModel);
		ResourceSet set = new ResourceSetImpl();
	
		set.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
		set.getResourceFactoryRegistry().getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
		set.createResource(typesUri);
		Resource r = set.getResource(typesUri, true);
		
        Model m = (Model) EcoreUtil.getObjectByType(r.getContents(), UMLPackage.Literals.MODEL);
		
		return m;
	}	
	
}

and these are the libraries I am using

org.eclipse.emf.common_2.7.0.v20120127-1122.jar
org.eclipse.emf.ecore.xmi_2.7.0.v20120127-1122.jar
org.eclipse.emf.ecore_2.7.0.v20120127-1122.jar
org.eclipse.emf.mapping.ecore2xml_2.7.0.v20120130-0943.jar
org.eclipse.uml2.common_1.6.0.v201105021727.jar
org.eclipse.uml2.uml_3.2.100.v201108110105.jar
