[namedgraphs] Problem running example

[Anne B. <bj...@si...>]

Hi!
I'm playing around with the Semantic Web Cllient Library. I have been trying to get the example from the website to work, but without luck. Could you tell me what is going wrong with it.

My code is:
public void queryWeb(){

       SemanticWebClient semweb = new SemanticWebClient();
       semweb.getConfig().setValue(SemanticWebClientConfig.MAXSTEPS, "5" );

        // Specify the query.
String queryString1 =   "PREFIX foaf:<http://xmlns.com/foaf/0.1/> " +
"SELECT DISTINCT ?friendsname ?friendshomepage ?foafsname ?foafshomepage  " +
"WHERE {" +
 " { <http://richard.cyganiak.de/foaf.rdf#cygri> foaf:knows ?friend ." +
  "  ?friend foaf:mbox_sha1sum ?mbox . " +
  "  ?friendsURI foaf:mbox_sha1sum ?mbox ." +
  "  ?friendsURI foaf:name ?friendsname ." +
  "  ?friendsURI foaf:homepage ?friendshomepage . }" +
  "  OPTIONAL { ?friendsURI foaf:knows ?foaf ." +
   "            ?foaf foaf:name ?foafsname ." +
   "            ?foaf foaf:homepage ?foafshomepage ." +
   "          } " +
 "  }" ;

// Execute the query and obtain results.
Query query = QueryFactory.create(queryString1);
QueryExecution qe = QueryExecutionFactory.create(query, semweb.asJenaModel("default"));
ResultSet results = qe.execSelect();
//Output query results.
ResultSetFormatter.out(System.out, results, query);

List<String> suc = semweb.successfullyDereferencedURIs();
Set<String> unsuc = semweb.unsuccessfullyDereferencedURIs();
semweb.close();
System.out.println("Successfull uris");
for(String s : suc){System.out.println(s);}
System.out.println("Unsuccessfull uris");
for(String s : unsuc){System.out.println(s);}
  }



and the result is:
