Hey,
This might be a simple problem, but I've had no success solving it so far, even though I tried a couple of different solutions found on this forum and in the EMF FAQ. But back to the problem at hand.
I'm trying to load an UML model in a stand alone application, but for most of the solutions I've tried I've gotten the following result: "NoClassDefFoundError".
I'm using the following code
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 ModelCode {
private URI typesUri = null;
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);
UMLPackage.eINSTANCE.eClass();
set.createResource(typesUri);
Resource r = null;
r = set.getResource(typesUri, true);
Model m = (Model) EcoreUtil.getObjectByType(r.getContents(), UMLPackage.Literals.MODEL);
return m;
}
}
When debugging I'm encountering the error at "r = set.getResource(typesUri, true);". The following is the error message I'm getting when trying to run this code.

Hi
You really should not use explicit JARs; they keep changing. Use a
tchnology such as MANIFEST.MF that sorts it out for you.
You can see the JAR using Navigate->Open Type Hierarchy, or Show
In->Package EXplorer.
For me, today, it's in org.eclipse.uml2.common_2.1.0.v20160201-0937.jar
