I am trying to connect Java to Orient database. I am using the OrientDB version
2.2.12. The code is not giving an ouput.It is showing an error called as plocal
not found.
It is showing only remote found.I have been trying a lot. Could you please me?
Thanking You in anticipation,
A OrientDB user
package orientdb_conn;
import com.tinkerpop.blueprints.Edge;
import com.tinkerpop.blueprints.Vertex;
import com.tinkerpop.blueprints.impls.orient.OrientGraph;
public class Orientdb_conn {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
OrientGraph graph = new
OrientGraph("plocal:D:/orientdb-community-2.2.12/databases");
try{
Vertex luca = graph.addVertex(null); // 1st OPERATION: IMPLICITLY BEGINS
TRANSACTION
luca.setProperty( "name", "Luca" );
Vertex marko = graph.addVertex(null);
marko.setProperty( "name", "Marko" );
Edge lucaKnowsMarko = graph.addEdge(null, luca, marko, "knows");
graph.commit();
} catch( Exception e ) {
graph.rollback();
}}
}
Output:-
