Here is my snipped of code for my loader as it would not read any file outside of files inside the folder

public class EMFModelLoad {
public RootPIM load(String file) {
// Initialise the model
PIMPackage.eINSTANCE.eClass();

// Register the XMI resource factory for the .website extension
Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
Map<String, Object> m = reg.getExtensionToFactoryMap();
m.put("PIM", new XMIResourceFactoryImpl());

// Obtain a new resource set
ResourceSet resSet = new ResourceSetImpl();
resSet.setResourceFactoryRegistry(reg);
// resSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("PIM", new
// XMLResourceFactoryImpl());
Resource resource = resSet.getResource(URI.createURI(file), true);

RootPIM pimRoot = (RootPIM) resource.getContents().get(0);
// return pimRoot;
return pimRoot;

}

}

Hi

(Ed Merks usually answers this one very promptly. Pending his better response...)

URI.createURI is ok for creating a direct naming representation of e.g. an nsURI. It is not often appropriate for an accessible URI.

You probably want createFileURI standalone or createPlatformResourceURI within the IDE.

That said, your configuration and use of the global registry is unusual, but superficially looks ok and shouldn't lead to the message you observe.

If changing createURI makes no difference then it's time for the debugger. Perhaps you are not using the correct level of the global registry.

Regards

Ed Willink

Thank you for your reply i have fixed the code by using

Resource resource = resSet.getResource(URI.createFileURI(file), true);

This helped so much

Many Thanks
