Question

I have a problem with the DBpedia SPARQL endpoint.
When I call this query it doesn’t return any results:

SELECT DISTINCT * WHERE {
  <http://dbpedia.org/resource/Santiago_Bernabéu_Stadium> rdfs:label ?label . 
  OPTIONAL {
    <http://dbpedia.org/resource/Santiago_Bernabéu_Stadium> geo:lat ?lat ;
                                                            geo:long ?long .
  }
}

SPARQL results

But when I change the URL to something like <http://dbpedia.org/resource/Sierra_Nevada_(Spain)> it works perfectly. I call it from Java using Apache Commons HttpClient (tried with POST and GET).
I think the problem is in é with accent, but I can´t find any encoding solving my problem. Do you know how could I fix it?

Answer 1

It looks I found the answer.
Using URLEncoder was not solution as long it was changing other characters (like braces).
But I’ve found that I should use URIref class from Jena.
Problem solved!
