Hi guys:

I am having really a hard time with TDB, I was planning to post everything
here but I googled first and found a post on the stachoverflow that has the
same issue, but with no answer.

It does have answer.

Here is my code too:

What is it trying to do? And what happens?

This is unrunnable and unexplained.

System.out.println("creting infeer dataset ");

  Dataset dataset = TDBFactory.createDataset(data.getInferredResultsPath());

  System.out.println("creting OntModel ");

  OntModel Infmodel =

   ModelFactory.createOntologyModel(PelletReasonerFactory.THE_SPEC,

    dataset.getNamedModel(this.URL));

  System.out.println("adding schema (OWL) to OntModel");

  Infmodel.add(this.owl);

  System.out.println("adding data (RDF) to OntModel ");

  Infmodel.add(data.tdb);

  System.out.println("creting ModelExtractor ");

  ModelExtractor ext = new ModelExtractor(Infmodel);

System.out.println("replacing OntModel by the Extracted Model");

  dataset.replaceNamedModel(this.URL, ext.extractModel());

System.out.println("saving infead model");

  Infmodel.close();

  System.out.println("closing infeed dataset");

  dataset.close();


Please guys let me know what I should do. a couple of thing to say:

I am using apache-jena-2.10.0
also, when I run the reasoner on a small tab, it works perfectly.
