I am started working on xtext, I have created some DSL grammer and Generated the artifacts,After that i ran that as eclipse application and created the sample.dmodel (example), In the editor i have added some langauge realted stuff which grammer accepts.

problem:
once the dmodel is created i need to read that particular file and get the contents from them..I have tried using loading the Resource concept. but it is not working.. I am getting resource factory is needed.

new DomainModelStandaloneSetup().createInjectorAndDoEMFRegistration();
ResourceSet rs = new ResourceSetImpl();

Resource resource = rs.getResource(URI.createURI("C:\\Users\\runtime-EclipseXtext\\sampleprj\\src\\mymodel.dmodel"), true);

DomainModel model = (DomainModel) resource.getContents().get(0);
System.out.println(model.getElements().size());

can you guys please help me how to do it.

how/from where do you try to read the model?

Hi Christian Dietrich

Thanks for your Response...From your response i need to use google juice injector. But in the xtext document to load the model they are doing from the dosetup method inside the StandloneSetup. when iam trying to load resource i was getting resource factory needed. And more over iam not very sure how to use google injector. if you have any sample code..please help me out,
Thanks in advance.

P.S: if you execute this from a java main the following will work

Injector i = new DomainmodelStandaloneSetup().createInjectorAndDoEMFRegistration();
ResourceSet rs = i.getInstance(ResourceSet.class);
Resource r = rs.getResource(URI.createURI("model/test.dmodel"), true);
r.load(null);
System.out.println(r.getContents().get(0));
