Hi Stephane, Hi Ed,
thanks for helpful support. Let me add some more details.
Of course I used the "ScaResourceFactoryImpl" like shown in the following
code snippet (The hardcoded extension was only for testing purpose).
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put(
"composite",
new ScaResourceFactoryImpl()
);
I'm not definitely sure whether I'm running on an OSGi environment but I
launched the App inside Eclipse as a oAW workflow which as far as I now is
running on Eclipse plattform. Furthere more the occuring Execption depicts
that the ScaResourceImpl overloads the load() method an calls some nativ
java code to parse the URI:
Caused by: java.net.MalformedURLException: unknown protocol: platform
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)
at org.eclipse.stp.sca.util.ScaResourceImpl.load(ScaResourceImp l.java:72)
I'll follow your suggestions and try to find the cause of my problem, I'll
post the solution when I fixed it.

I'm quite sure that a workflow runs as a standard Java application,
i.e., what you get when you do "Run As->Java Application" rather than
what you get when you do "Run As->Eclipse Application". Don't confuse
where you run it from with how its running.

Who is specifying the URL that's being used. You can't use a
platform:/resource or platform:/plugin URL if you are running as a
standard Java Application.

You'll likely need to use file: URI like what you get with
URI.createFileURI. Be sure the file path is absolute, i.e., use
java.io.File.getAbsolutePath...

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.

Stephane,
What the failure tells me is that Mischa is most likely not running as
an OSGi application. Eclipse registers the "platform" protocol properly
so a URL using it should work properly...

Hi all,
now it works! I just build the org.eclipse.stp.sc.sca PlugIn from the trunk
(Where the whole load methode of the ScaResourceImpl is commented out).
With other words the official SCA version (0.9.0.200806121858) related to
Eclipse Ganymede won't work in standalone applications. Use the current
trunk version instead.
