I am trying to run a transformation from an RCP app. (Yes, QVTO is nice
to import from i.e. MS-Excel).

I follow the instructions here:

However the execution fails with the following error:

Could not find unit
'platform:/resource/NetXStudio/transforms/XLS2NETXSTUDIO.qvt o'

The referred resource does exist, but still the execution fails.

I have debugged a bit more and the following code in UnitResolverFactory
seems not to find some factories:

public UnitResolverFactory getFactory(Object source) {
for (UnitResolverFactory nextFactory : fFactories) {
if(nextFactory.isAccepted(source)) {
return nextFactory;
return null;

Here fFactories is empty.

Could it be I need to provide some EPackages as this is an RCP?
(Although, I do register my EMF models ).

Thanks Christophe
