I'm not sure to understand because how could I configure neo4j server whith
the org.apache.commons.configuration.Configuration?
Wich property do I need to add for having the access to the port 7575
secured by a password?
Thanks

Dima,
thanks for pointing that out.
We'll add it to the documentation.
The Neo4j-Server is not hosted at maven-central, because it is more of a
product than a library, which you normally just download as installable
archive. Only if you develop server-extensions (or right now want to run
Hi
This may seem a silly question but the fact is I am still new to
java so maybe I dont know.
In neo4j Api I noticed Node is said to be interface. If Node is
interface then how can it be instantiated as object. As far as I know you
cannot instantiate an interface object.
So why
All the node instances that you need will provided to you via the
GraphDatabaseService API, create an instance of EmbeddedGraphDatabaseService
and use its methods to
find and created nodes and relationships.
See these tutorials:

Hi Mathias,
EmbeddedReadOnlyGraphDatabase is not quite what it seems, and I think should be
deprecated/removed. The correct way for database instances to become consistent
is through the HA protocol.

Hey Eddy,
sorry about the late reply, I'm on vacation, so I've been checking email
rather sporadically.
I'm not sure exactly what causes your problem, since we seem to have lost
the nested exception at some point (presumably a java/jpype/python thing),
but generally, what you are seeing is the
I installed a 2-node HA neo4j linux cluster based on instructions provided in
http://wiki.neo4j.org/content/High_Availability_Cluster. For standalone
deafult neo4j server there is a neo4j-server.properties file in which it
contains a line
org.neo4j.server.webserver.port=7474
that allows webadmin
Hello,
Each node in the HA cluster will have a webadmin available. If you're running
multiple instances on the same machine, you will need to adjust the ports to
avoid clashes.
Are you just setting up for testing, or is this a production environment?
Cheers,
Andreas

I think a bit of elaboration might be in order.
EmbeddedReadOnlyGraphDatabase was created for one specific purpose:
Being able to interactively introspect a graph without having to shut down
the application that uses it.
Specifically the tools that we wanted to support with this were the Neo4j
FWIW, I really like the idea of a remote API. Not only for tooling, but as an
alternative to bulkier and more abstracted REST APIs. One way to think of it
could be a high performance, binary-formatted REST API - if the overhead of
HTTP isn't too much (and I seriously doubt that it would be -
The HA cluster is for testing initially. If everything works fine, we'll need

Last couple of days I have worked improving upon the Enhanced API and made some

Hi, I'm new to graph databases and have been trying to understand the power
of Cypher and/or Gremlin as a way to develop suggestion queries. I've
watched a few webinars and read through some of the documentation but I've
had a hard time figuring out complex suggestion type queries other
We don't have a guide specifically about transitioning from a testing
environment to production, though the HA and database tuning sections of the
manual will be most relevant when you're going through that exercise. The
coordinators are, at the moment, deployed as a zookeeper cluster. The

Howdy Graphistas!
I hope someone with graph modeling experience can help me with a pattern I'm
working on.
I have two kinds of edges that may connect nodes, one is very heavy
meaning that it has a high weight and if two nodes are connected by it this
relationship it is very important, but there
