Hello,

I'm new to EMF, I'm given 2 xmi files (a metamodel and a model) and I have to load them in my project.
When I try to load the model I have this error Exception in thread "main" org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Package with uri '*' not found. (, 8, 17)

I read a lot about this error and people says that we have to register the package but I don't really understand what that means. All i have is this 2 xmi files.

Thank to y'all

I can only guess what exactly you've tried and what the resources look like... Maybe all you need to do is register the metadata's namespace URI before you load the model:

    EPackage ePackage = (EPackage)metadataModel.getContents().get(0);
    resourceSet.getPackageRegistry().put(ePackage .getNsURI(), ePackage);
