[ATL] extracting a model with 3.0 EMF Specific VM [message #103090]

I'm attempting to programmatically use the API for 3.0
to perform a transformation and extract the result
into a resource. I create a model using a model
factory and give with a "path" options with the
uri that I want to extract it to. After populating it
with a transformation, I'm attempting to extract
it using an extract method from the extractor, again
with the "path" option set, and get the following exception

org.eclipse.m2m.atl.core.ATLCoreException: No Resource found, unable to
extract to path: platform:/resource/ccc/library.ecore
at org.eclipse.m2m.atl.core.emf.EMFExtractor.extract(EMFExtract or.java:63)
at org.eclipse.m2m.atl.core.emf.EMFExtractor.extract(EMFExtract or.java:77)

It appears that the extract method assume that the model
already has an associated resource. Where should I have set this?

thanks
Andy.

hi,
i am extracting a model to a .ecore file with ATL3 simply with:
//Save to .ecore
atlASMModel.getModelLoader().save(atlASMModel, "file:/" +
destinationFile);

this saves the model in its xmi format.

is this what you want to do?

Skander,

It looks like your using a different API to me; my code is
given below. If I set the LAUNCHER_NAME to
"Regular VM (with debugger)", I get an Eclipse resource
containing the output model. When the name is set to
"EMF-specific VM", I get an exception. Having made
some changes overnight, the exception is now:

org.eclipse.m2m.atl.engine.emfvm.VMException

launcher.initialize(options);

options.put(ASMFactory.OPTION_MODEL_PATH, inResource.getURI().toString());
IModel inModel = modelFactory.newModel(inMetaModel, options);
injector.inject(inModel, inResource.getURI().toString());

launcher.addInModel(inModel, "in", "IN");

// options used by Regular VM
Map<String, Object> options = new HashMap<String, Object>();
options.put(ASMFactory.OPTION_NEW_MODEL, "true");
options.put(ASMFactory.OPTION_MODEL_NAME, "out Model");
options.put(ASMFactory.OPTION_MODEL_PATH, outUri);
// options used by EMF specific VM
options.put("path", outUri);
IModel outModel = modelFactory.newModel(outMetaModel, options);

launcher.addOutModel(outModel, "out", "OUT");

// EMF specific VM expects allowInterModelReferences passed to launch
launcher.launch(ILauncher.RUN_MODE, new NullProgressMonitor(), options,
getClass().getResourceAsStream(M2M_ASM));

extractor.extract(outModel, outUri);

i'm using ATL 3.0.0.v200903171237

here is my code:
public ASMModel injectAtlFileToAtlModel
(String sourceFile, String destinationFile){
// TODO Auto-generated method stub
System.out.println("injection started!");
ASMModel atlASMModel = null;

try
{

AtlModelHandler amh = AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);
ModelFactory factory = CoreService.createModelFactory("EMF");
IReferenceModel atlMM = factory.newReferenceModel();

System.out.println(CoreService.getInjectorsNames());

IInjector injector = CoreService.getInjector("EMF"); //new ASMInjector();
injector.inject(atlMM, atlMMpath);

//Create an empty ATL model
InputStream input = new FileInputStream(sourceFile);
//Now Parsing from atl file to atl model
//Create a new parser
AtlParser atlParser = AtlParser.getDefault();
//Create a new ASMModel
amh.createModelLoader().newModel("Marte2ATL", "file:/" + sourceFile,
atlASMModel); //ASMFactory;
//Launch Parsing
atlASMModel = atlParser.parseToModel(input);

//Save to .ecore
atlASMModel.getModelLoader().save(atlASMModel, "file:/" + destinationFile);
//////////////////////
System.out.println("injection Ended!");
}
catch (Exception e)
{
e.printStackTrace();
}
return atlASMModel;
}

I'm using the API from the interim update site:

Hello,

The resource is created during the transformation, when new elements are
created into the output model.
So you may have an error during the transformation. To debug, note that
as EMFModel have getResource() and setResource() methods.

Regards,

William

William,

Thanks; I did have a problem with my transformation.
