Hi Ankit,
Its a common error: remember that there is no protocol called D in the
following uris
String sUri = "D://albums/vc-db-1.rdf";
String sUri2 = "D://albums/ankitverma.rdf";
Rather change them to String sURI="file://D:/albums..."

Subject: Persisting rdf model to mysql database
Hi all,
I am trying to persist a rdf file into mysql database using
following code
package test;
import com.hp.hpl.jena.db.DBConnection;
import com.hp.hpl.jena.db.IDBConnection;
import com.hp.hpl.jena.db.ModelRDB;
public class Test extends Object {
public static void main(String args[]) {
// Pass two RDF documents, connection string,
String sUri = "D://albums/vc-db-1.rdf";
String sUri2 = "D://albums/ankitverma.rdf";
// As before ...
String M_DB_URL = "jdbc:mysql://localhost:3306/test";
String M_DB_USER = "root";
String M_DB_PASSWD = "";
String M_DB = "MySQL";
String M_DBDRIVER_CLASS = "com.mysql.jdbc.Driver";
try{
// load the the driver class
Class.forName(M_DBDRIVER_CLASS);
// create a database connection
IDBConnection conn = new DBConnection(M_DB_URL, M_DB_USER,
M_DB_PASSWD, M_DB);
// Create and read first model
ModelRDB model1 = ModelRDB.createModel(conn, "one");
model1.read(sUri);
// Create and read second model
ModelRDB model2 = ModelRDB.createModel(conn, "two");
model2.read(sUri2);
} catch (Exception e) {
System.out.println("Failed: " + e);
}
}
}
But facing the error
Failed: com.hp.hpl.jena.shared.JenaException:
java.net.MalformedURLException: unknown protocol: d
Please suggest if anything is missing
Thanks and Regards
Ankit Verma
