Hi all,

First, excuse the English poor.

I would like the help of someone with this problem. I want to launch an
ATL Transformation by running a Java programm (Code of the main class
below). Firstly I tried this with the simple "Author2Person"
Transformation and it works fine, putting as argument the following models:
--trans file:/C:/dev/workspace/TestAtl
/models/Families2Persons/Families2Persons.asm
--in
IN=file:/C:/dev/workspace/TestAtl/models/Families2Persons/sa mple-Families.ecore
Families=file:/C:/dev/TestAtl/models/Families2Persons/Famili es.ecore EMF
--out OUT=file:/C:/dev/TestAtl/models/Families2Persons/sample-Pers ons.ecore
Persons=file:/C:/dev/workspace/TestAtl/models/Families2Perso ns/Persons.ecore
EMF

I got the output model what i want.
I want to run now the same class (Code of the main class below) with other
argument of models (uml2), for example:

--trans file:/C:/dev/workspace/TestAtl/trans/test.asm
--in IN=file:/C:/dev/workspace/TestAtl/models/model_test.uml2
UML=file:/C:/dev/workspace/TestAtl/metamodel/Superstructure. uml EMF
//Obs.: UML metamodel withdrawn from
org.eclipse.uml2.source_2.1.1.v200708301222. It's the metamodel UML2
correct?
--in ASPECTS=file:/C:/dev/workspace/TestAtl/models/model_aspects. uml2
UML=file:/C:/dev/workspace/TestAtl/metamodel/Superstructure. uml EMF
--out OUT=file:/C:/dev/workspace/TestAtl/model/test_out.uml2
UML=file:/C:/dev/workspace/TestAtl/metamodel/Superstructure. uml EMF

Throw the following error:
org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri
'http://www.eclipse.org/uml2/2.0.0/UML' not found.
(file:/C:/dev/workspace/TestAtl/metamodel/Superstructure.uml , 3, 58)
