Most probably, it is very easy: 

change the definiton of queryBegin:

static String queryBegin = "PREFIX actor: 
  <http://icas.ipb.pt/myontologies/actor.owl#> \r\n" +
                           "PREFIX space: 
  <http://icas.ipb.pt/myontologies/spatial.owl#> \r\n" +
    "PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>";
 
For the SPARQL query, you need to define *all* prefixes that are used in
it (i.e. in the query string), here, this means you have to define rdf.
