[QVTo] Failed to resolve metamodel [message #498753]

Hello everybody.

I've got a challenge in writing my own qvto-example.

first line declares the metamodel for my output models:

modeltype XPAR uses 'http://xpar.org/3.1.2/xpar312';

here an "Failed to resolve Metamodel" error is shown.

I have taken a look with the Metamodel Explorer View and I found the model, inside of a ecore file at the workspace location. the URI used above is the same as shown in bracket here.
What else has to be done?
Did I already make something wrong?

Sorry for this issue, I am quite new to the whole M2M-Transformation stuff. Embarrassed

And thanks alot for your help! Smile

Thanks a lot Radek,

it works fine.

For those having the same problem, here the how-to in short:
rightclick on your qvt-project in package-explorer -> properties ->QVT Settings -> Metamodel Mappings -> Add (source model uri := nsURI; target model uri := ecore-file location uri)

than refresh the project.

The error mentioned above should not be there anymore. For me it worked fine. Thumbs Up

Sorry again for that "newby" question and thanks alot for your instant support. perfect!

Chris
