i'm new on Eclipse epsilon.
I have to do a model2model transformation.
I have the UML diagrams and c++ codes of the starting model and the target model.
I don't know how to use these files for generate the starting metamodel (.ecore) and after that, instanciate the starting model which will be used for the transformation in ETL.

can someone help me?

Hi Fedrico,

> I have the UML diagrams and c++ codes of the starting model and the target model.

What do you mean by "c++ codes" of the starting/target model? Also, what format are your "UML diagrams" in?

Best,
Dimitris

The UML diagrams are in uml 2.0 format, the c++ codes are the source codes that contains the implementations of the classes represented in the uml diagrams.

Are you trying to transform UML models to C++ code?

Which tool did you use to produce the UML diagrams? Did you use Papyrus, or did you use something else?

Hi Fedrico,

Generating an Ecore metamodel from a UML class diagram makes sense (and the Eclipse UML2 project already provides some support for this) but I'm not sure I understand the role of the C++ code you mentioned in the process.

If the UML2 tooling linked above is not sufficient for the task at hand, could you please write a longer message and explain what you are trying to achieve in more detail? Please also attach small examples of UML/C++ input files that your transformation should consume and hand-crafted versions of the Ecore/model files you would like it to produce as output.

Best,
Dimitris

The C++ codes are useless. Now i have found the way to create EMF project starting from UML diagrams using eclipse epsilon. But during the load of the UML diagrams i recive the following errors.

We need a bit more information: the errors suggested that those attributes (I assume they are attributes?) are lacking a type. How did you produce such a metamodel?

It would speed up things if you could produce a minimal working example that reproduces your issue.
