Hello,
I'm working with the Virtuoso Jena Driver API to query a local DBpedia
ontology and process information with Jena API.
When launching a query with an ORDER BY clause, the following exception
is thrown:
Exception in thread "main" com.hp.hpl.jena.shared.JenaException: Can not
create ResultSet.:virtuoso.jdbc3.VirtuosoException: Tag 20 not defined.
Here an example of SPARQL query that won't work:
SELECT ?title
WHERE { { <http://dbpedia.org/resource/Unreal_II:_The_Awakening>
<http://xmlns.com/foaf/0.1/name> ?title } UNION {
<http://dbpedia.org/resource/Unreal_II:_The_Awakening>
<http://www.w3.org/2000/01/rdf-schema#label> ?title } }
ORDER BY ?title
I found the virt_jena and virtjdbc3 jars in the OpenSource Virtuoso Wiki
(here
<http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VOSDownload#Jena>).
As I'd like to use them in my application, I'm wondering if there is an
official release of this API, if it is maintained and if there is any
Maven 2 artifact set.
