Hi

I have written this following code to load a local RDF file to my local Virtuoso instance with the help of Jena. But even for the smallest of RDF file it times out. Can anybody please point out what could be the possible cause

import com.hp.hpl.jena.query.*; import com.hp.hpl.jena.rdf.model.Model; import com.hp.hpl.jena.rdf.model.ModelFactory; import com.hp.hpl.jena.rdf.model.RDFNode; import com.hp.hpl.jena.update.UpdateException; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.InputStream; import virtuoso.jena.driver.VirtDataSource; import virtuoso.jena.driver.VirtGraph; import virtuoso.jena.driver.VirtuosoUpdateFactory; import virtuoso.jena.driver.VirtuosoUpdateRequest;


 /**

public class Main {

    public static void main(String[] args) throws FileNotFoundException {

VirtGraph set = new VirtGraph ("jdbc:virtuoso://localhost:1111", "dba", "dba");

   InputStream in = new FileInputStream("C://Users//Dell//Documents//NetBeansProjects//CoKo//build//web//files//test11.rdf");

  VirtuosoUpdateRequest vur = VirtuosoUpdateFactory.read(in,set);

                vur.exec();

System.out.println("done");


    }


}

Maybe you're confusing '//' with '\\'.
A forward slash is no special character and can be written just like that ( so use only 1 forward slash).

A backslash is a special character, and should be escaped by using another hence why you use 2 backslashes if you want to use a "real" backslash.

tried that also, but with no effect :(
