I have a Sparql Query, that counts BNodes:


        SimpleSelectQuery selectQuery =3D new SimpleSelectQuery();

        Variable vMAStatistics =3D new Variable("vMAStatistics");
        Variable vDefaultEvent =3D new Variable("vDefaultEvent");
        Variable vEvent        =3D new Variable("vEvent");

        Set<TriplePattern> patterns =3D new HashSet<TriplePattern>();
        patterns.add(new SimpleTriplePattern(uri, MACCSTATS.mobileAppStatis=
tic, vMAStatistics));
        patterns.add(new SimpleTriplePattern(vMAStatistics, MACCSTATS.defau=
ltEvent, vDefaultEvent));
        patterns.add(new SimpleTriplePattern(vDefaultEvent, MACCSTATS.event=
, vEvent));

        BasicGraphPattern bgp =3D new SimpleBasicGraphPattern(patterns);
        SimpleGroupGraphPattern queryPattern =3D new SimpleGroupGraphPatter=
n();
        queryPattern.addGraphPattern(bgp);

        selectQuery.setQueryPattern(queryPattern);
        // wich fields we want to get
        selectQuery.addSelection(vEvent);

        // Execute Query
       ResultSet resultSet =3D tcManager.executeSparqlQuery(selectQuery, gr=
aph);

        while (resultSet.hasNext()) {
            t =3D resultSet.next();

            GraphNode gnEvent =3D new GraphNode(t.get("vEvent"), graph);
            Iterator<Resource> iterPhone =3D gnEvent.getObjects(MACCSTATS.p=
hone);

            while (iterPhone.hasNext()){
            }
        }



Is it possible that i can select or get the BNode "vEvent ", so that i can =
get the objects or can't i access the predicates  because it's an BNode (wh=
at i think)?
I tried different Casts, but it wouldn't work.

cheers
Oli
