Hi i am student doing a project for my school and i trying to insert data
i am inserting triples with jena adapter into my Oracle Database from a .nt
file. 4 tables are being created FAMILY_NS, FAMILY_TPL, RDFB_FAMILY and
RDFC_FAMILY. my data are in N-Triple format.i want to know why i can't view my
data through sql-developer in my database.do i store those data or not?
here is the code i use to insert data into my database
import java.io.*;
import com.hp.hpl.jena.query.*;
import com.hp.hpl.jena.graph.*;
import com.hp.hpl.jena.rdf.model.*;
import com.hp.hpl.jena.util.*;
import oracle.spatial.rdf.client.jena.*;
public class Bulk {
public static void main(String[] args) throws Exception
{
String szJdbcURL = "jdbc:oracle:thin:@192.168.2.3:1521:orcl";
String szUser = "kostas";
String szPasswd = "welcome";
String szModelName = "Family";
Oracle oracle = new Oracle(szJdbcURL, szUser, szPasswd);
GraphOracleSem graph = new GraphOracleSem(oracle, szModelName);
PrintStream psOut = System.out;
String dirname = "C:\\users\\CoCo\\Desktop\\file";
File fileDir = new File(dirname);
String[] szAllFiles = fileDir.list();
// loop through all the files in a directory
for (int idx = 0; idx < szAllFiles.length; idx++) {
String szIndFileName = dirname + File.separator + szAllFiles[idx];
psOut.println("process to [ID = " + idx + " ] file " + szIndFileName);
psOut.flush();
try {
// Model model =
FileManager.get().loadModel("C:\\users\\CoCo\\Desktop\\file\\example.nt");
InputStream is = new FileInputStream(szIndFileName);
graph.getBulkUpdateHandler().prepareBulk(
is, // input stream
"http://www.recshop.fake/cd";, // base URI
"N-TRIPLE", // data file type: can be RDF/XML, N-TRIPLE,
etc.
null, // tablespace
null, // flags
null, // listener
null // staging table name.
);
is.close();
}
catch (Throwable t) {
psOut.println("Hit exception " + t.getMessage());
}
}
}
}
