Hi ,

I am new to AMW and i am just trying the example Class2Relational example.

From Class2Relational-Trace.amw file i clicked on "save weaving model in
to ecore format" menu & i saved this as a Class2Relational-Trace.ecore.

then again Class2Relational-Trace.ecore file i clicked on "Extract
Atl0.2model-to-Atl file" menu & it's generating the Atl file but it is
empty.

I'm using eclipse 3.3 version.

i don't know in this example how they have generated
Class2Relational-ATL-0.2.atl file from Class2Relational-Trace.amw.

can anybody help me.

Thanks in Advance
viji

Hi,

This menu saves the weaving metamodel model into an ".ecore" file.
This is not a transformation model (in ATL), thus the "extraction into
ATL" action will fail.

Actually, the "Class2Relational-Trace.amw" is the trace generated by the
already modified transformation, "Class2Relational-WithWTracer.atl". The
generation of the trace is generated by the last action (transformation)
of the example.

You need to execute the "ATL2WTracer.atl" transformation first. This
transformation generates a "Class2Relational-WithWTracer.ecore", which is
a transformation model. This is the model that should be extracted into
ATL. The extracted ATL is used to generate the AMW trace model.

Regards,

Marcos.
