HI,

        Finally I succeed to call the
function UpdateExecutionFactory.createRemote. Thanks for the comments.

Here is my configuration

Fuseki server
java -Xmx1200M -jar fuseki-server.jar --update --mem
--loc=D:/fuseki-0.2.2/TD /ds2

and the insert query code

public class search {
static final String inputFileName = "http://localhost:3030/";;
public static void main(String[] args) throws IOException{
  Model model =ModelFactory.createOntologyModel();

         // use the FileManager to find the input file
         InputStream in = FileManager.get().open(inputFileName);
         if (in == null) {
             throw new IllegalArgumentException( "File: " + inputFileName +
" not found");
         }

         model.read(inputFileName+"per2.owl");
         in.close();

What's in model at this point?

         String queryString ="PREFIX xmlns:
<http://localhost:3030/per1.owl#>\r\n"
+
                             "PREFIX base:<http://localhost:3030/per1.owl

\r"+

                     "PREFIX xsd:<http://www.w3.org/2001/XMLSchema#>\r"+
                                   "INSERT DATA" +
                     "{"+
                           "<http://localhost:3030/per1.owl#name1>\n" +
                            "xmlns:hasFirstname \"Rex\"^^ xsd:string;" +
                              "}";

xmlns is not a good choice of prefix name.

         GraphStore gs=GraphStoreFactory.create(model);
         gs.setDefaultGraph(model.getGraph());
         UpdateRequest ur = UpdateFactory.create(queryString);
         Update update = ur.getOperations().get(0);
         UpdateExecutionFactory.createRemote(ur,"
http://localhost:3030/per2.owl";);
         UpdateAction.execute(ur,gs);
         System.out.println(update);


     // some codes ....

         qe.close();
         }
}

I am wondering why it is not updating the ontology??

regards

What does the Fuseki log say?


UpdateExecutionFactory.createRemote(ur,"http://localhost:3030/per2.owl";);


per2.owl is not a SPARQL update service endpoint.

http://localhost:3030/ds2/update is the SPARQL update service endpoint.
