[news.eclipse.modeling.m2m] Re: [ATL] launching a transformation program

["Hugues Dubourg" <hdubourg@xxxxxxxxxxxxx>]

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):

GRAVE: java.io.FileNotFoundException: http://www.eclipse.org/uml2/2.1.0/UML

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.
