I am trying to use external parameters with ATL transformations. I am followed the help at ATL_Howtos.
I have also downloaded the org.eclipse.m2m.atl.projectors.xml plugin developed for Juno from docatlanmod.emn.fr and located it in the Eclipse installation folder. In particular, I have trying to copy it to the droppings and plugins folders, even to the ATL proyect folder in my workspace, but it does not work.
I get the error:
Error loading platform:/resource/ATLProyect/InputModels/parameters.xml: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'null' not found. (platform:/resource/ATLProyect/InputModels/parameters.xml, 1, 13)
