Hallo everybody,
I try to deserialize a gmfgraph-file created by eclipse but while loading
an exception is thrown, although I am able to open the file with the
standard gmfgraph editor in Eclipse.
Thanks for your help.
Cheers,
Jörg
My Code:
...
String path = "model/ComponentModel.gmfgraph";
URI uri = URI.createFileURI(new File(path).getAbsolutePath());
Registry registry = Resource.Factory.Registry.INSTANCE;
Map m = registry.getExtensionToFactoryMap();
m.put("gmfgraph", new XMIResourceFactoryImpl());
ResourceSet resourceSet = new ResourceSetImpl();
Resource ecoreResource = resourceSet.getResource(uri, true);
...
Error Message:
Exception in thread "main"

Ok, I found the reason by own.
>>In addition, you'll also need to register your package, which happens as a
side effect of accessing XyzPackage.eINSTANCE. For example, to register the
library model, add the following line to your main program:
LibraryPackage packageInstance = LibraryPackage.eINSTANCE; <<
