Hi ,
I'm really new to Marmotta.
Now I'm trying to run this simple code in eclipse
ClientConfiguration config = new ClientConfiguration();
config.addEndpoint(new SPARQLEndpoint("DBPedia
(SPARQL)","http://dbpedia.org/sparql","^http://dbpedia\\.org/resource/.*";));
LDClientService ldclient = new LDClient(config);
String uriBerlin = "http://dbpedia.org/resource/Berlin";; ClientResponse
respBerlin = ldclient.retrieveResource(uriBerlin);
RepositoryConnection conBerlin =
respBerlin.getTriples().getConnection();
but I got the following error, how I can parse SPARQL/XML format?! :
23:38:04.284 [main] ERROR o.a.m.l.s.p.AbstractHttpProvider - Unknown error
