Jochen,
It should be as simple as this:
ResourceSet resourceSet = new ResourceSetImpl();
Resource ecoreResource =
resourceSet.getResource(<uri-of-*.ecore-resource>, true);
EPackage ePackage = (EPackage)ecoreResource.getContents().get(0);
If you're loading a resource form the work space, use
URI.createPlatformResourceURI(iFile.getFullPath().toString() , true), and
if it's a file system file, use URI.createFileURI(new
File(<path>).getAbsolutePath()).
Looking at what EcoreEditor does to load a model and then let you edit
it shows it in a fancier context...

I'm trying to build a plug-in that processes Ecore models, looks for
annotations and patterns and stuff like that. For that I believe I need
to be able to access the model somehow. I was expecting to find some
sort of API that allows the loading of an ecore file and returns the
root package of the model, or something like that. So far I've been
unable to locate such an API. I tried working through the
org.eclipse.emf.importer stuff, but I don't really see what this is
doing and documentation is rather sparse.
<br>
<br>
Can anyone point me to the right place where to start looking or does
anyone even have example code?
<br>
<br>
Thanks
<br>
Jochen
