[news.eclipse.stp.sca-tools] Re: ecore model instance

["Mischa" <Mischa.Hoechsmann@xxxxxxxxx>]

Once again, thx for help.

Ed, referencing my model instance (sca.composite) using the file: protocol 
works great, like you told me. Unfortunately this works only when using the 
default ResourceFactoryImpl which in turn make problems loading the 
model-content (The issue i already mentioned, "Class 'composite' not 
found").

Using the "ScaResourceFactoryImpl" I still run into the problem "unknown 
protocol: platform", no matter whether I'm specifing the URI using the 
file:/... notation (URI.createFileURI() woun't help either).

This seams to be the end of my SCA jouney since for me it looks like i can't 
use the model out of Eclipse at the time being (using 
"ScaResourceFactoryImpl()").
At least I gain insight into the EMF Persistence API and a more detailed 
knowlede about what's an URI all about.
