Hi All,

im pretty new in using Model Transformations. I'm trying to develop a Eclipse Plugin. This Plugin is a Wizard. Every step this wizard is going I'm trying to execute a QVTO M2M - transformation with the TransformationExecutor class.

But its getting kind of frustrating because I cant create the necessary Ressources for the transformation. Don't know really which type is really necessary and how to initialise these ressources. I tried initialise these URIs / Ressources in several ways but getting only errors.. as you can see in my code below. Where is my stupid error ? Smile

ConvertEcore2Ecore testTransformation = new ConvertEcore2Ecore(); (TransformationExecutor class)

URI inURI = URI.createPlatformResourceURI("C://XXX//models//inmodel.xmi", true);
Resource inResource = new ResourceSetImpl().getResource(inURI, true);

URI outURI = URI.createPlatformResourceURI("platform:/resource/XXX/model//outmodel.xmi", true);
Resource outResource = new ResourceSetImpl().createResource(outURI);

testTransformation.convertEcore2Ecore(inResource, outResource);

Thx 4 your answers...

Hi

Both your usages of createPlatformResourceURI are wrong. The first has a
very file-like argument so use createFileURI, the second has a redundant
platform:/resource

yeah sure, I know that this is the point, that the URIs aren't working and so the resource can't be created. But in fact i've no idea what would be the right URI definition.

I've a QVTO Projekt by example named QVTOProject and in this project there is a folder model and in this folder i got a modelinstance .xmi file which is the Input for my transformation.

So i just want to create an working URI / Resource for this file. I tried many things referencing like a file or like a resource or whatever and didn't find real information which createXURI I should take or a tutorial what is for what und what is working with what.

So it's a little bit frustrating getting stuck here...

Anyone have a working conclusion using this example implementation described above?

thx 4 your answers
