Ok guys thank you all! Sorry but I'm new to Jena and Semantic web
applications and I'm trying to figure out how things works.

Andy,
Perfect! Thanks a lot for your help.

Hi Andy.
I implemented the entire SPI at the DatasetGraph and Graph level. It got to the
point where I had overridden more methods than not. In addition writes are not
supported and contains methods which call find(ANY, ANY, ANY) play havoc with
an on demand
LOL. The perils of a succinct update with no detail!
I understand the Jena SPI supports read/writes via transactions and I also
know that the wrapper classes provide a best effort for some of the
overridden methods which do not always sit well when materializing triples.

I think there is some confusion over a "remote" graph here.
With the standard SPARQL protocols, you can either query a remote
endpoint or fetch a remote graph - SPARQL Graph Store Protocol (and
dataset FWIW).
