Hello,
I'd like to launch an ATL transformation from some Java code. The
transformation is KDM to UML 2.1. I've already written such a transformation
for the J2SE to KDM case which works fine.
I did test the transformation using the UML21.ecore file and the EMF
registry from within the Eclipse plugin. Both case worked fine.
However when calling the transformation from some piece of Java code,
nothing simply comes out. Here is what the code looks like:
final AtlEMFModelHandler modelHandler =
(AtlEMFModelHandler)AtlModelHandler.getDefault(AtlModelHandl er.AMH_EMF );
ASMModel mofMM = modelHandler.getMof();
//Get MModels
try{
kdmMM = modelHandler.loadModel( "kdm", mofMM, kdmMMurl.openStream());
umlMM = modelHandler.loadModel("uml2" , mofMM, umlMMurl.openStream());
}catch (IOException e){
e.printStackTrace();
}
//Get the kdm Model
kdmModel = modelHandler.loadModel("kdm", kdmMM , kdmModelurl.openStream());
//transform
final AtlLauncher launcher = AtlLauncher.getDefault();
final Map<String, ASMModel> models = new HashMap<String, ASMModel>();
final Map<?, ?> asmParams = Collections.EMPTY_MAP;
final List<?> superimpose = Collections.EMPTY_LIST;
final Map<?, ?> options = Collections.EMPTY_MAP;
final Map<?, ?> libs = Collections.EMPTY_MAP;
ASMModel outputInstance = modelHandler.newModel("OUT", null, umlMM);
models.put( "kdm", kdmMM );
models.put( "uml2", umlMM);
models.put( "IN", kdmModel );
models.put( "OUT", outputInstance);
launcher.launch( transformation, libs, models, asmParams, superimpose,
options );
//The save code...
When loading the UML metamodel from the ecore file, I got lots of Warning
like:
28 avr. 2008 15:28:38 org.eclipse.m2m.atl.drivers.emf4atl.ASMEMFModel
addReferencedExtentsFor
ATTENTION: Resource for org.eclipse.emf.ecore.impl.EClassImpl@cdb06e
(eProxyURI:
platform:/plugin/org.eclipse.emf.ecore/model/Ecore.ecore#//E ModelElement) is
null; cannot be referenced
I tried loading the UML metamodel from the EMF registry using:
umlMM =
modelHandler.loadModel("uml2",mofMM,"uri:http://www.eclipse.org/uml2/2.1.0/UML");
I then don't have any warning but still no result.
What am I doing wrong?
Thanks a lot

Have you already tried to do something like this (loading the UML2
metamodel from the EMF registry)?
umlMM = modelHandler.loadModel("uml2", mofMM,
URI.createURI("http://www.eclipse.org/uml2/2.1.0/UML"));
Do you know exactly from which line of your program comes your error?
Best regards,
Hugo

Thanks for your swift response Hugo,
I tried to use the EMF registry indeed, but I specified the URI as a String
parameter:
>> umlMM =
>> modelHandler.loadModel("uml2",mofMM,"uri:http://www.eclipse.org/uml2/2.1.0/UML");
I got no error message, but no result either.
When using a new URI as you wrote:
>umlMM = modelHandler.loadModel("uml2", mofMM,
>URI.createURI("http://www.eclipse.org/uml2/2.1.0/UML"));
I now have a null pointer exception whose trace is (sorry it's a bit long):

I guess there must a problem matching the metamodel with the given URI. Do
you know where this issue could come from?
I keep debugging my Java code. If ever I make any further breakthrough, I
will let you know.

Is the UML2 plugin (version 2.1) installed and loaded onto your Eclipse?
If another version is installed, you may try with the corresponding URI.
