Hi,
I'm trying to access a model created in EMF through Java code, basically as done here, in Chapter 7.
However, when trying to load my model, I get the error:
Package with uri 'http://MFDMetaInst/2.0' not found.
This package is my metamodel, which is obviously not registered, and should be, before loading the model. So my question is, how do I do this?
I would assume that it should happen somewhere in this block, but I'm not exactly sure where and (most of all) how.
public MFD load(String loc) {
// Initialize the model
MFDMetaInstPackage.eINSTANCE.eClass();
// Register the XMI resource factory for the .mfdmetainst extension
Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
Map<String, Object> m = reg.getExtensionToFactoryMap();
m.put("mfdmetainst", new XMIResourceFactoryImpl());
// Obtain a new resource set
ResourceSet resSet = new ResourceSetImpl();
// Get the resource
Resource resource = resSet.getResource(URI
.createURI(loc), true);
where the variable loc is a string with the location of the model to be loaded.
Could anyone help me out?

RJ,
Is 'http://MFDMetaInst/2.0' the actual value of
MFDMetaInstPackage.eNS_URI? You can see where the exception is being
thrown and use the debugger to understand why a matching package isn't
found; I'd expect the package to be in the global package registry based
on the code you've shown...
