Hi Nina, 

I tested with the following curl call:

curl -X POST -d
'dataset_uri=http://ambit.uni-plovdiv.bg:8080/ambit2/dataset/1054' -d
'prediction_feature=http://ambit.uni-plovdiv.bg:8080/ambit2/feature/357709' -d 'dataset_service=http://ambit.uni-plovdiv.bg:8080/ambit2/dataset' http://localhost:8080/OpenTox-dev/algorithm/J48 -iv

and got an error:
com.hp.hpl.jena.shared.JenaException: org.xml.sax.SAXParseException:
Element type "ot:http" must be followed by either attribute
specifications, ">" or "/>".

This happens in the following code snippet (2nd line throws the
Exception):
OntModel ontmodel = OT.createModel();
ontmodel.read(inRDF,null);

So the JENA read() method seems to dislike the RDF. inRDF is of type
InputStream. 

I'll go online on skype, so we can figure out what's going on. 

Regards,
Tobias
