My first OrientDB - Help

[jeffg]

Trying to get my feet wet with OrientDB and BluePrints and I'm getting
an error. I copied the account files from the demo databases into my
path. Also, how do I create a database? Seems to want to open an
existing db.

import com.tinkerpop.blueprints.pgm.*;
import com.tinkerpop.blueprints.pgm.impls.orientdb.OrientGraph;
import com.orientechnologies.*;

Graph graph = new TinkerGraph();
Graph db = new OrientGraph(dataPath("account.och"));
Vertex a = graph.addVertex(null);
Vertex b = graph.addVertex(null);
a.setProperty("name", "marko");
a.setProperty("name", "peter");
Edge e = graph.addEdge(null, a, b, "knows");
graph.shutdown();

Hi,

It looks like you are mixing TinkerGraph and OrientDB. You want to just use OrientDB.

Thus,

Graph graph = new OrientGraph("local:/tmp/adirectory/graph");

Vertex a = graph.addVertex(null);
Vertex b = graph.addVertex(null);
a.setProperty("name", "marko");
a.setProperty("name", "peter");
Edge e = graph.addEdge(null, a, b, "knows");
graph.shutdown();

Also, you need the "local:" prefix and you don't need TinkerGraph.

Hope that helps,
Marko.

Thanks.. figured it just as you posed... I didn't have "local:" in
front of it.
