You can also set up a REST server and use the SPARQL endpoint in the REST api, and then just call those from your Java program:

ResultSequence rs = session.submitRequest(request); while (rs.hasNext()) { ResultItem item = rs.next(); // handle the item } session.close(); Wrap that up in a utility class, parameterize it as needed, and you'll never have to think about it again. -- Mike On 5 Jun 2014, at 09:43 , Marc Limotte <[email protected]> wrote: > Hi. > > I'd like to run a SPARQL query from Java.
