Virtuoso TripleStore에서 RDF 트리플을로드 할 때 오류가 발생했습니다.

Question

질문이 있습니다.

나는 http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtJenaProvider의 sample8을 따르고 있습니다.

package ExampleVirtuoso; 

import com.hp.hpl.jena.query.*; 
import com.hp.hpl.jena.rdf.model.RDFNode; 
import virtuoso.jena.driver.*; 

public class ExampleVirtuoso { 
    public static void main(String[] args) { 
     /*   STEP 1   */ 
     VirtGraph set = new VirtGraph("jdbc:virtuoso://localhost:1111", "dba", "dba"); 

     /*   STEP 2   */ 
     System.out.println("\nexecute: CLEAR GRAPH <http://test1>"); 
     String str = "CLEAR GRAPH <http://test1>"; 
     VirtuosoUpdateRequest vur = VirtuosoUpdateFactory.create(str, set); 
     vur.exec(); 

     System.out.println("\nexecute: INSERT INTO GRAPH <http://test1> { <aa> <bb> 'cc' . <aa1> <bb1> 123. }"); 
     str = "INSERT INTO GRAPH <http://test1> { <aa> <bb> 'cc' . <aa1> <bb1> 123. }"; 
     vur = VirtuosoUpdateFactory.create(str, set); 
     vur.exec(); 

     /*   STEP 3   */ 
     /*  Select all data in virtuoso */ 
     System.out.println("\nexecute: SELECT * FROM <http://test1> WHERE { ?s ?p ?o }"); 
     Query sparql = QueryFactory.create("SELECT * FROM <http://test1> WHERE { ?s ?p ?o }"); 

     /*   STEP 4   */ 
     VirtuosoQueryExecution vqe = VirtuosoQueryExecutionFactory.create(sparql, set); 

     ResultSet results = vqe.execSelect(); 
     while (results.hasNext()) { 
      QuerySolution rs = results.nextSolution(); 
      RDFNode s = rs.get("s"); 
      RDFNode p = rs.get("p"); 
      RDFNode o = rs.get("o"); 
      System.out.println(" { " + s + " " + p + " " + o + " . }"); 
     } 

     System.out.println("\nexecute: DELETE FROM GRAPH <http://test1> { <aa> <bb> 'cc' }"); 
     str = "DELETE FROM GRAPH <http://test1> { <aa> <bb> 'cc' }"; 
     vur = VirtuosoUpdateFactory.create(str, set); 
     vur.exec(); 

     System.out.println("\nexecute: SELECT * FROM <http://test1> WHERE { ?s ?p ?o }"); 
     vqe = VirtuosoQueryExecutionFactory.create(sparql, set); 
     results = vqe.execSelect(); 
     while (results.hasNext()) { 
      QuerySolution rs = results.nextSolution(); 
      RDFNode s = rs.get("s"); 
      RDFNode p = rs.get("p"); 
      RDFNode o = rs.get("o"); 
      System.out.println(" { " + s + " " + p + " " + o + " . }"); 
     } 

    } 
} 

내 빌드 경로에 추가 한이 라이브러리 : 특히

,이 코드가

virtjdbc3.jar 
virt_jena.jar 
Jena libs 

을하지만이 코드를 컴파일 할 때,이 오류가 발생합니다 :

Exception in thread "main" com.hp.hpl.jena.shared.JenaException: virtuoso.jdbc3.VirtuosoException: Connection failed: Connection refused: connect 
    at virtuoso.jena.driver.VirtGraph.<init>(VirtGraph.java:206)

변경하려고 시도했습니다.

virt_jena.jar

virt_jena2.jar

와

,하지만 난이 오류를 얻을 :

I 전제가 기능적으로 거장의에 대해 무지하고 내가 몇 가지 초기 단계를 생략 할 수 있습니다. 라이브러리를 다운로드했습니다. http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VOSDownload#Jena%20Provider

여기서 내가 뭘 잘못하고 있니?

Answer 1

이 첫 번째 예외는 필요한 서비스를 호스팅하지 않는 시스템에 연결하려고 했으므로 연결 문자열이 잘못되었거나 필요한 서비스를 시작하거나 방화벽 설정 등을 확인해야한다고 알려줍니다. "연결이 거부되었습니다"는 연결하려는 서비스의 설정에 문제가있는 것 같습니다.
