Hi,
This kind of exceptions (package with uri * not found) usually mean that
you're missing some package registrations ... though uri "null" I rarely
see.
How did you create the "model.xmi" file? Was that a file exported by an
external modeler such as Enterprise architect? If it is, I'd say the
issue is with the exported file. What does it do if you try to open it
in the ecore editor through "open with => other => Sample Reflective
Ecore Model Editor" ? If it fails through this, then the ecore model
itself is wrong (malformed xml, missing namespace, ...).
The "convert to EMF" item is provided as a bridge for exported models
which aren't "well" exported and thus incompatible with EMF. If using it
doesn't solve the issue (again, try opening your model with the
reflective editor before even trying Acceleo), please let us know.

Hi,
You're not supposed to modify manually this exported xmi file.
UML:Class is the metatype of your class called A and there is no
UML:Toto metatype in the UML metamodel(excepted if you have created a
stereotype). That's why the action "Convert to EMF" doesn't work in your
context.
So I don't understand the link between your UML model and your metamodel
containing a metatype Toto. Could you give us more details of your use case?
Regards,
Freddy.

Hi,
I don't really know where to begin ... first of all, you're not using
"ecore" as metamodel : your model is clearly an UML model, thus its
metamodel is UML.
Second : you cannot manually alter the XML and hope for the result to
work. "UML:Class" means "my object is of type 'Class' in the 'UML'
namespace". Changing it to "UML:Toto" can only fail : there is no "Toto"
metaclass in the UML metamodel.
Starting from the beginning. When you export this model from ArgoUML to
an XMI (or better yet "EMF XMI" if the option is present in ArgoUML);
can you load the model within Eclipse with the action "Open With =>
Other... => UML model editor"? If not, change the expression from
whatever you have to ".uml" and try again.
If you still cannot open the file in the UML editor, try and run the
action "Convert to EMF" (this action serves as a bridge from external
modelers to EMF) and try opening the file in the UML editor again. If
that fails, it means that ArgoUML simply doesn't export an UML file that
we can read with EMF.
If you manage to open the file in the UML editor, you'll be able to
alter the model from there.
