I have created a tiny model, using ModelFactory.createDefaultModel() to create my initially empty model,

So, having done this, is there any way that I can persist this to a Fuseki database running on a remote server?
Thanks for any help,

Append and replace as per HTTP.
RFC 7231: 4.3.3. POST

- Extending a database through an append operation.
...
(any ordering implied by "extend" is irrelevant for a set of quads)
RFC 7231: 4.3.4. PUT
The PUT method requests that the state of the target resource be
created or replaced with the state defined by the representation
enclosed in the request message payload.

Not really - the GET/POST/PUT on the dataset itself is just normal use
of HTTP.
The "Graph Store Protocol" for managing a graph store. What it really
adds is the naming convention, ?default and ?graph.

The SPARQL Graph Store Protocol does not mention this. Fuseki supports
REST-ish PUT/POST/GET on the dataset URL.
Currently, you need to send it yourself -- HttpOp.execHttpPost has lots
for support for that e.g. see DatasetGraphAccessorHTTP for sending a
model - generalise to datasets.
We have been talking about this on dev@
http://mail-archives.apache.org/mod_mbox/jena-dev/201508.mbox/%3C55BE6A0B.5020404%40apache.org%3E

That’s great - in the end I solved the problem by adding the line:

Many thanks for all your help (and patience).

Out of the box, the UI only responds to the localhost. If you access it
from a different machine, or (unfortunately) the same machine but its
external IP address, the Fuseki refuses access to the JSON calls driving
the interface. You can change the default to a user/password.

Hah! I hadn’t configured a dataset. Now rectified by setting the config.ttl to be one of the templates provided
as part of the build.
Curiously though, although I can see this when I run a browser locally on the server, and set the url to "localhost:3030",
I don't see any datasets listed when I explicitly specify the ip address, nor when I try to access it from any other box.
I realise that I’ve gone *waaaay* off topic now, so unless the answer is obvious, don't feel the need to address this new
issue. I’ll try searching in the fuseki knowledge base. Oh and btw: I don’t have any firewall set up, afaik (although
if I did, I’d expect this to block the entire fuseki site, rather than just the dataset listings.
Sheeesh, this is tiring :-/

The dataset (not the graph) needs to exist before the operation is
attempted. e.g. via the UI, or via startup with "--update /ds" for a
name of "ds".
http://foobar:3030/myDatasetName/data
/myDatasetName -- dataset name - must exist
/myDatasetName/data -- service endpoint for GSP on that dataset (thats'
the default name
and update must enabled. How are you running the server?

You’ll think me very dense, but how do I specify the dataset name? When I specify the dummy URL that
you suggest (I don’t care what the dataset is called at the moment) I get:

Wrong URL: It will be something like
http://foobar:3030/myDatasetName/data
which is the service endpoint for the Graph Store protocol by default.
(It needs a config file to change it - the UI puts it there
automatically) where the query one is
http://foobar:3030/myDatasetName/query and the SPARQL Update one is
http://foobar:3030/myDatasetName/update.
"myDatasetName" is whatever you you decided to call it.

OK, I’ve created the model, which I can successfully print out using 'model.write(System.out, "RDF/XML-ABBREV”);'
However, when I use your code below, and do an acc.put(model) I find that there is nothing on the server, even though
no errors are indicated.
The URL that I am using for the createHTTP request is the URL of my Fuseki server: "http://foobar:3030”, which I
am inspecting using the built in web-based browser.
At the risk of stretching your patience, can you explain what I’m doing wrong? Given that there are no errors, I would
have expected the model to appear somewhere or other :-/ If I specify an invalid URL (e.g. incorrect port) then
I get an error, which seems to indicate that the code is actually talking to the server.
Thanks,
Andy D.

There may be a better answer for this, but at the very least, you can serialize your triples/quads and use SPARQL Update to send them to your Fuseki instance.
