java加载拖缆CSparql中的Rdf文件

Question

我想在RdfStreamer中加载RDF。我已经创建了一个查询，它在arrayList中提取查询Sparql的结果集，并在流中获取该结果，以便传递给主类。这是我的拖缆代码：

package main.java.eu.larkc.csparql.sr4ld2014.streamer;
import java.util.ArrayList;
import java.util.Random;
import org.apache.jena.query.Query;
import org.apache.jena.query.QueryExecution;
import org.apache.jena.query.QueryExecutionFactory;
import org.apache.jena.query.QueryFactory;
import org.apache.jena.query.ResultSet;
import org.apache.jena.rdf.model.Model;
import org.apache.jena.util.FileManager;
import eu.larkc.csparql.cep.api.RdfQuadruple;
import eu.larkc.csparql.cep.api.RdfStream;

public class SensorsStreamer extends RdfStream implements Runnable  {



    private long sleepTime;
    private String baseUri;
    private ArrayList<String> prova=new ArrayList<String>();


    public ArrayList<String> loadToFile(){
        Model modelMisurazioni= FileManager.get().loadModel("misurazioni.rdf");

        String s1 = "PREFIX  rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>\n" +

                "WHERE\n" +
                "  { ?s ?proprietà ?idSensore. "
                + "?s ds:idsensore ?idSensore.}\n" +
                "";
        Query queryM= QueryFactory.create(s1);
        QueryExecution qexec=QueryExecutionFactory.create(queryM, modelMisurazioni);

            System.out.println("QUERY 1");
            ResultSet results = qexec.execSelect();


            //ResultSetFormatter.out(System.out, results) ;

            int i=0;
            while(results.hasNext()){
            prova.add( results.next().getLiteral("idSensore").getLexicalForm() );
            System.out.println(prova.get(i++).toString() );
            }
return prova;
        }




    public SensorsStreamer(String iri, String baseUri,long sleepTime) {
        super(iri);
        this.sleepTime = sleepTime;
        this.baseUri = baseUri;
        prova=loadToFile();
    }




    public void run() {

        Random random = new Random();
        String sensorIndex;
        int subjectIndex;
        int roomIndex;
        int observationIndex;
        int numberOfPerson;

        while(true){
            try{

                numberOfPerson = random.nextInt(3);
                subjectIndex = random.nextInt(5);
                roomIndex = random.nextInt(5);
                observationIndex = random.nextInt(Integer.MAX_VALUE);

                RdfQuadruple q = new RdfQuadruple(baseUri + "sensor" + provva2, baseUri + "observes", baseUri + "observation" + observationIndex, System.currentTimeMillis());
                this.put(q);                
                if(numberOfPerson < 2){
                    q = new RdfQuadruple(baseUri + "observation" + observationIndex, baseUri + "who", baseUri+"person" + subjectIndex, System.currentTimeMillis());
                    this.put(q);
                } else {
                    for(int i = 0 ; i < numberOfPerson ; i++){
                        q = new RdfQuadruple(baseUri + "observation" + observationIndex, baseUri + "who", baseUri+"person" + subjectIndex, System.currentTimeMillis());
                        this.put(q);
                        subjectIndex = random.nextInt(5);
                    }
                }               
                q = new RdfQuadruple(baseUri + "observation" + observationIndex, baseUri + "where", baseUri+"room" + roomIndex, System.currentTimeMillis());
                this.put(q);

                Thread.sleep(sleepTime);

            } catch(Exception e){
                e.printStackTrace();
            }
        }

    }

}

eclipse的错误是：
