"a registered resource factory is needed" outside the generated editor [message #377406]

Thu, 01 May 2003 13:12

Eclipse User

I have an EMF model which is running perfectly in the generated editor.
Now I want to load the model from a file in some code outside of the
generated editor. I get the exception below. For loading the file I
perform the steps as in the generated editor (see below).

How do I register the required resource factory?

Thanks for any hints,
Chris

=== code snippet starts here ===
List factories = new ArrayList();

factories.add(new ModelItemProviderAdapterFactory());
adapterFactory = new ComposedAdapterFactory(factories);
BasicCommandStack commandStack = new BasicCommandStack();
editingDomain = new AdapterFactoryEditingDomain(adapterFactory,
commandStack);

String inputFile = "f:/workspace/eva/Releases13.model";
Resource resource = editingDomain.loadResource
(URI.createFileURI(inputFile).toString());

Chris,

You need to register resource factory.

You can use call
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put
to register resource factory.

And this is sample codes for xmi format file which is using
XMIResource interface.
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put
("*", <--- your file extension
new XMIResourceFactoryImpl() <--- the class to resource factory
{
public Resource createResource(URI uri)
{
XMIResource xmiResource = new XMIResourceImpl(uri);
return xmiResource;
}
});

You can provide your own resource factory class and resource class to
handle
your own file (if it is not xmi or xml file).

For more infomation, please refer to EMF users guide, session 3.4.2 and
3.4.3.

Regards,
Shu

That helped.

I was wondering why I don't have to do this when I am using the
generated editor plugin. But the plugin seems to register the resource
factories during plugin initialization - which is missing in my
stand-alone app.

Next time I will do RTFM.

Thanks a lot,
Chris

Hi

I'm not sure what you really mean. There is an *.ecore file associated with Xtext, optionally manually entered, optional autogenerated. Use ctrl-shift-R to locate it by name.

If you want to see a model perspective of the *.xtext in the Sample Ecore Editor. Sorry that stopped working a couple of years ago.

Hi

Your visual snippet has so many things that make me uncomfortable I'm not sure where to start.

But first, do not attach a new problem to a 14 year old thread. Software moves much to fast for there to be any sensible prospect that your new problem is a continuation.

Do not use visual snippets. Your code cannot be cut and paste as a mini repro. Your exceptions are hideously truncated forcing major guessing. Why not cut and paste so that we see it all and Google searches can find similar content?

I am a Windows user, but I never use "\" in code. "/" works fine in all C/Java based software.

I suspect that your problem is "file:///". I would need to read the specification to be sure what it actually means. URI.createFileURI is so much easier.

As was already suggested a \ in a URI is a bad idea because it is NOT a path separator in a URI, it's a path separator only on Windows and only as far as java.io.File is concerned. Generally when using file-based access, use URI.createFileURI(file.getAbsolutePath())) to create the URI from the java.io.File. Make sure it's absolute.

Hi

Assuming that "Metamodel contains several classifiers with same name" is a surprise to you, you almost certainly have a metamodel schizophrenia problem; only load each distinct metamodel by one mechanism; see recent posts / Google.

In the end, this is the EMF forum, not the ATL forum so you might ask on that specific forum instead:
