By the advice of Ed Willink (thank again), I should post my last unanswered post here:
--- POST

I am developing a model-based tool, PIM -> PSM -> Code, and I am using EMF ATL to accomplish the M2M transformations. My problem is simple: My ATL mapping works betwen UML2 and Java metamodels, except in Primitive Types.

If some with more experience could look to my files and take a shot, it will help me a lot!

UML metamodel: By URI, but you could use that as reference: UML.ecore;
Java metamodel: Java-20040316.ecore; (To be built gradually);
ATL mapping: UML2JAVA.atl;

My (UML) input Model: exampleUMLModel_PIM.xmi;

My (Java) output Model: out.j2se5; ==> At line 18 it is supposed to have a Primitive Type, right?

tanks in advance

--- Continuation
This is my Atl configuration, hope this help a little more ... Should I need to register something more?
