You’re using the wrong factory J The factory you’re after, is probably a simple XMIResourceFactory, which would typically be registered against a ‘*’ extension catchall.

Hi all,


after I have continued with my project and started to learn how to use Sirius, I face another, for you most probably trivial problem.

I created a model with Sirius with a custom ending (for example .basicfamily from the Sirius tutorial) but I can’t find a way, to use this model with Henshin.


I copied the model into a project in the first instance of eclipse. There I try to load it with the following line:

EGraph graph = new EGraphImpl(resourceSet.getResource("example.basicfamily"));


But this throws the exception:

Cannot create a resource for 'example.basicfamily'; a registered resource factory is needed


Through some searching I learned, that I have to load the resource factory mentioned in the plugin.xml from the edit project. So I added the following line before the instantiation of the EGraph:


Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("basicfamily", new org.eclipse.sirius.sample.basicfamily.provider.BasicfamilyItemProviderAdapterFactory());


This results in another exception:

org.eclipse.sirius.sample.basicfamily.provider.BasicfamilyItemProviderAdapterFactory cannot be cast to org.eclipse.emf.ecore.resource.Resource$Factory


Sadly I have no idea how to solve this problem.


Best regards,
