Hello everyone, I'm new here and I'm new with Xtext!

I'm trying to make a grammar for importing Schemas, for example, XSD.
I'm trying to import using "importURI" attribute, but I'm not getting any success on this...

See my grammar code below:

Import:
	'import' importURI=STRING 'as' name=ID
;

And i also added a new extension for ResourceServiceProvider as XSD:

<extension
       point="org.eclipse.xtext.extension_resourceServiceProvider">
    	<resourceServiceProvider
          class="mygrammar.resource..XsdResourceServiceProvider"
          uriExtension="xsd">
    </resourceServiceProvider>
 </extension>

But when I test with, for example, the following syntax: import "test.xsd" as Idm
My ResourceServiceProvider is never called, I tried to overrides ImportUriGlobalScopeProvider, but the method "getScope" is never called with my resource...

And I also need to create a "free" URI, for example, I would like to use a URI like: "C:/test.xsd".

I tried to follow some topics here, but without success :/

Can anyone help me with this? ;)

Thanks a lot!

how do you call this code?
standalone / eclipse ? if eclipse is the xsd file in a project. if standalone how do you populate the resourceset. imports just make things visible. its not a follow the import and load the resource

here is an example on how to provide a resource service provider for uml

Hello Christian, thank you for your reply.

I'm using Eclipse!

Since i created this topic i got a success when I put XSD file in the same project, but i would like to load a file outside the project, using my own strategy for reading..
And how can i get the "name" attribute for Import?

I will read your shared link

Thank you!
