Hi,

Through the option "Discovery->Discoverers->Discover Java Model from Java Project" i got the sourcemodel.ecore model, but when i consult the Window->Show View->Other->Metamodel Explorer in the Workspace item i see the following error.

Hello,

The MoDisco Java Model Discoverer produces a model that conforms to the Java metamodel provided by MoDisco (cf. the MoDisco documentation from help.eclipse.org, "MoDisco User Guide -> Technologies -> Java -> Java discoverer").
Thus it should produces an ".xmi" file (i.e. a model) and not an ".ecore" file (i.e. a metamodel).
You should change your file extension to reflect this, and then you will be able to open the produced Java model with any EMF reflective editor, such as the MoDisco Model Browser for instance.
I hope this helps.

Hello Hugo,

Can i transform models (no metamodels) with QVTo? Change a plus sign for a minus sign for instance?

Thanks.

Of course, the purpose of model-to-model transformation languages is to transform any kinds of models.
So you can transform your Java model to any other model (that conform to any other metamodel).
You should take a look to the first part of this presentation that introduces the base concepts of Model Driven Engineering as well as of model transformation.
On a same topic, you should also take a look to the introduction of the ATL transformation language core concepts.

Hello Hugo,

I consulted the documentation that you provided me and some concepts are more cleare.

Basically that i need is define a java program, then generate a model for it, transform it and finally obtain the java program again.

I would make the transformation with QVTo.

What is the most appropriate way to do this according to you?

This work is for my grade thesis and i believe that you could help me much.

Best regards.
