Problem loading data from jena

Question

Hi, two issues when loading data into Oracle from a jena model:
1. The incremental and batch load both works well except when we add a triple with a literal types as double:
triple = new Triple(dirNode.asNode(), Node.createURI("http://www.w3.org/2003/01/geo/wgs84_pos#long"), Node.createLiteral(geopos.getLongitude().toString(), null,      (RDFDatatype) XSDDatatype.XSDdouble));
graph.add(triple);
We get the error:
GRAVE: Could not add triple
java.sql.BatchUpdateException: ORA-55303: Fallo en el constructor SDO_RDF_TRIPLE_S: Simple case: SQLERRM=ORA-55328: fallo al intentar insertar el valor literal "-5.9278863"^^<http://www.w3.org/2001/XMLSchema#double>
ORA-06512: en "MDSYS.MD", línea 1723
ORA-06512: en "MDSYS.MDERR", línea 17
ORA-06512: en "MDSYS.SDO_RDF_TRIPLE_S", línea 211

     at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:3530)
     at oracle.jdbc.driver.OraclePreparedStatementWrapper.executeUpdate(OraclePreparedStatementWrapper.java:1062)
2. The bulk load simply does not work:
((OracleBulkUpdateHandler) graph.getBulkUpdateHandler()).addInBulk(GraphUtil.findAll(model.getGraph()), "sem_ts");
We get:
01-oct-2009 13:11:39 oracle.spatial.rdf.client.jena.SimpleLog warn
ADVERTENCIA: addInBulk: [92 ] sqle
java.sql.SQLException: ORA-44004: nombre de SQL cualificado no válido

     at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:802)
In both case our conexion is something like:
public static String conexion = "jdbc:oracle:thin:user/pass@ourserver:1521:ourdb";
Any idea? Thanks

Answer 1

Hi Wu, we have included your code in a java test ang got the same problem.
Our installation is Oracle Database 11.2.0.1.0. Then we added the 'Semantic patch' 11_2_sem and followed the instructions to create a tablespace and the RDF/SEM network. Finally we create a model as [explained here|http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11828/sdo_rdf_concepts.htm#CHDEDFFA] .
Some text in the exception is spanish; basically it seems to say 'fails inserting the literal value'... The rest of data in the app has been correctly inserted.
This is the java test:
public class PruebaOracleTest extends TestCase {
     String jdbcUrl = "jdbc:oracle:thin:user/pass@server:1521:bd";
     public void testInsertData() throws Exception {
          Oracle oracle = new Oracle(jdbcUrl, null, null);
          GraphOracleSem graph = new GraphOracleSem(oracle, "ARTICLES");
          ModelOracleSem model = new ModelOracleSem(graph);
          Model inMemoryJenaModel = ModelFactory.createDefaultModel();
          long lStartTime = System.currentTimeMillis();
          System.out.println("testCustomerMisc: start");
          Triple t = new Triple(Node.createURI("http://sub"), Node
                    .createURI("http://www.w3.org/2003/01/geo/wgs84_pos#long"),
                    Node.createLiteral("-5.9278863", null,
                              (RDFDatatype) XSDDatatype.XSDdouble));
          graph.add(t);
          graph.flushAdd();
          String queryString = "SELECT * " + "WHERE { "
                    + " ?subject ?predicate ?object . " + "} ";
          Query query = QueryFactory.create(queryString);
          QueryExecution qexec = QueryExecutionFactory.create(query, model);
          ResultSet results;
               results = qexec.execSelect();
               ResultSetFormatter.out(System.out, results, query);
     public void testListTriples() throws Exception {
          Oracle oracle = new Oracle(jdbcUrl, null, null);
          GraphOracleSem graph = new GraphOracleSem(oracle, "ARTICLES");
          int cont = 0;
          ExtendedIterator it = graph.find(Triple.ANY);
          while (it.hasNext() && cont<100) {
               Triple t = (Triple) it.next();
               System.out.println(t.toString());
               cont++;
          graph.close();
          oracle.dispose();
     public void testCleanModel() throws Exception {
          Oracle oracle = new Oracle(jdbcUrl, null, null);
          GraphOracleSem graph = new GraphOracleSem(oracle, "ARTICLES");
          ModelOracleSem model = new ModelOracleSem(graph);
          model.removeAll();
          graph.close();
          oracle.dispose();
And this the exception we get:
