How do I connect to orientdb graph through rexster with bulbs?

Question

So, I'm using python3.2 and bulbs on mac-osx with rexster and orientdb. Details:

orientdb - standard download from their page

~/workspace/orientdb-community-1.7-rc1

Running the server, ./bin/server.sh

database - orientdb database ~/databases/orientdb/dev-db-01

rexster - standard checkout from github git clone git://github.com/tinkerpop/rexster.wiki.git ~/workspace/

config/rexster.xml:

        ...
        <graph>
        <graph-enabled>true</graph-enabled>
        <graph-name>dev-db-01</graph-name>
        <graph-type>orientgraph</graph-type>
        <graph-location>local:*<path to...>*/databases/orientdb/dev-db-01</graph-location>
        <properties>
            <username>admin</username>
            <password>admin</password>
        </properties>
        <extensions>
            <allows>
                <allow>tp:gremlin</allow>
            </allows>
        </extensions>
    </graph>
    ...

Python code:

from bulbs.rexster import Graph
from bulbs.config import Config
config = Config("http://localhost:8182/dev-db-01/", username="admin", password="admin")
g = Graph(config)

Problem:

What I think is that the url in the config of the python code is incorrect (I've tried all kinds of variations). But I don't know that; it works if I leave the rexster.xml untouched and just use the standard graph constructor; but then that's a problem, because it's not adding nodes to the orientdb database that I want, dev-db-01, it's putting them in a default database. So to make sure that I connected to the right database, I disabled all but the orientdb database I had created.

How do I make it connect properly?

Answer 1

The URL should include /graphs/ in the path:

http://localhost:8182/graphs/dev-db-01/
