Priority: Critical
Fix For: Jena 2.11.1
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());
}
