Hi,
I'm trying to use Edapt with a binary resource but I always get a null pointer back from this function:
String uri = ReleaseUtils.getNamespaceURI(resourceURI);
Does anyone know if it is even possible to use Edapt in combination with binary resources? I've already read some other forum topics where they discussed a similar problem, but they were all from 2009, so I hoped that this problem might have already been resolved in the meantime.
Thanks in advance for your help.

Hi Thomas,
ReleaseUtils.getNamespaceURI(resourceURI) will try to parse the file at the given URI with SAX in order to find the NS-URI of the model. This will only work for XML/XMI-Files.
But identifying the NS-URIs should be the only place where Edapt relies on a XMI-serialization as far as I know.
So you would have to introduce a different way of finding out the NS-URI of the model in the binary file. E.g. you could use the file-extension.
With this information you can get a Migrator instance and you should be able to identify the source release from the migrator.
String nsURI = getURIFromBinaryFile();
final Migrator migrator = MigratorRegistry.getInstance().getMigrator(nsURI);
final Release release = loopThroughReleasesAndFindReleaseWithNSURI(migrator, nsURI);
Furthermore you have to set a custom IResourceSetFactory on the migrator, which will make sure that Binary-Resources are created.
migrator.setResourceSetFactory(new IResourceSetFactory() {
@Override
public ResourceSet createResourceSet() {
ResourceSetImpl resourceSetImpl = new ResourceSetImpl();
resourceSetImpl.getResourceFactoryRegistry().getExtensionToFactoryMap().put("*",
new ResourceFactoryImpl() {
@Override
public Resource createResource(URI uri) {
return new BinaryResourceImpl(uri);
}
});
return resourceSetImpl;
}
});
I am not 100% sure that there are no other problems, but I think that this should work.
Could you share your experiences, if you are giving this a try?
Thanks and regards
Johannes
