The javadoc for DatasetFactory.create
/** Create a dataset with a default graph and no named graphs

It is reading in the remote URI into a local dataset. It will do a
GET which is why you get that error message.
Ahh. I failed to figure that out from the documentation.
You can't do SPARQL Update over HTTP GET (not that it is sending a
legal SPARQL update)
It does not associate the dataset with the remote URI for update
operations - and you can't do an update via GET.
Thanks Andy. I've created my own abstraction of an update service to
wrap either a local dataset or a remote endpoint. But I didn't want to
have some clunky home grown abstraction if there was one already in
Jena/ARQ.
jena-jdbc may give you that.

There is also a separate and experimental
