[emf-dev] Loading using streams

Title: Loading using streams

I was using emf serialization in my client code:

                java.lang.String data = null;
                try{
                       
                        // Read in data file and stringify it
                        File inpf = new File("data.xml");
                        FileInputStream fis = new FileInputStream(inpf);
                        byte [] b = new byte[5000];
                        int len = fis.read(b);
                        data = new java.lang.String(b,0,len);
                }
                catch(Exception e){}

                // Create input stream for resource
                ByteArrayInputStream ins = new ByteArrayInputStream(data.getBytes());

                // Create resource
                Resource resource = new XMLResourceImpl();

                // Create XMLMap, used for proper XML mapping. This is an empty Map,
                // it is using generated annotations for proper streaming
                XMLResource.XMLMap xmlMap = new XMLMapImpl();

                // Create options map for loading
                Map options = new HashMap();

                // Populate options
                options.put(XMLResource.OPTION_XML_MAP,xmlMap);

                // Initialize package, required for putting package in the registry
                CnaPackage cPackage = CnaPackageImpl.init();
                try{
                        resource.load(ins,options);
                }
                catch(Exception e){
                        e.printStackTrace();
                }

                // Get the root element from the resource
                Message message = (Message)(resource.getContents().get(0));

This seems to be fairly straightforward code, but it does not work, because I am not using resource, thus not defining URL. I have two options. Either to create resource just for the sake of URL or modify XMLHandler, XMLLoadImpl and XMLResourceImpl to check for nulls. Is it a bug? Feature? What is your recommendation?
