> Call to a remote strabon SPARQL endpoint that was working on Jena 2.11.1 do
> not work properly in version 2.12.0.
> This function :

> public void queryStrabon(final String query, final RDFDatatype datatype,
> final String... parameters) {
> final QuerySolutionMap map = new QuerySolutionMap();
> System.out.println(query);
> for (int i = 0; i < parameters.length; i += 2) {
> final RDFNode node =
> ResourceFactory.createTypedLiteral(parameters[i + 1], datatype);
> map.add(parameters[i], node);
> }
> final ParameterizedSparqlString pss = new
> ParameterizedSparqlString(query, map);
> final QueryExecution qe =
> QueryExecutionFactory.sparqlService(this.endpointURL + "Query",
> pss.asQuery());
> final ResultSet resultSet = qe.execSelect();
> while (resultSet.hasNext()) {
> System.out.println(resultSet.next());
> }
> System.out.println("lines: " + resultSet.getRowNumber());
