Hi Ashwini,
Thanks for the reply ,I changed the path u mentioned but giving the same error.
Same error - same cause?
Which .read causes this? Does the data have "D:" URIs?
As the others say, the old DB code has bee deprecated for new use for
some time now and we have got around to removing it from the latest release.
You may wish to upgrade.

Subject: RE: Persisting rdf model to mysql database
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..."
Ashwini.

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
