Hi Surajit,

I assume resultDataset variable is a Jena Model?

Here is one of the RDF files you've tried to upload

http://www.ideaconsult.net/downloads/maxtox/ambit2_22761.rdf
<http://www.ideaconsult.net/downloads/maxtox/ambit2_22761.rdf%20>

First observation there is no any ot:Dataset instance. There are multile
ot:DataEntry, but no dataset to where they belong.  This is definitely a
reason the dataset could not be imported - the parser simply doesn't find a
dataset to work with and does nothing.

Second observation - you have defined value of type double, but the value
itself is a string of 0 and 1s (the fingerprint).  This is at least not
correct and will most probably result in errors when parsing values.

       <ot:FeatureValue>
            <ot:value rdf:datatype="http://www.w3.org/2001/XMLSchema#double"

>0,0,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0</ot:value>
            <ot:feature rdf:resource="
http://localhost:8080/MaxtoxTest/feature/1_fingerprint"/>
          </ot:FeatureValue>

Ah, and (relatively minor)  issue - the feature URI
http://localhost:8080/MaxtoxTest/feature/1_fingerprint will not be
dereferencable, even if you are running feature service at your machine -
just because "localhost" means your machine for you, but my machine to me.

If you are not running feature service elsewehere it would be better to
either have anonymous node for it, or create it beforehand  (POST to
http://{host}/ambit2/feature)
and provide the URI in the dataset RDF.  TUM and NTUA developers can share
their experience/code as well.

Third,  this  code will not work as you might expect:

this.uploaded_URI = output.getText(); ,

because task RDF will be returned, not a single URI (you have specified
request.getClientInfo().getAcceptedMediaTypes().add(new
Preference<MediaType>(MediaType.APPLICATION_RDF_XML));

Hope this helps,
Nina
