Michael,
you shouldn't use 3.0.0 in production. It has not yet been tested for that!
Are you sure you use SDN-REST with simple mapping? It sounds like you get
the automatic deletion on cleaning the collection. (Or it is a bug, related
to the managed collection that's normally used to hold the rel
You shouldn't be able to write to the server directory at all. That's
really confusing.

JDBC is a database connection library (protocol) that Rickard Öberg and I
implemented for Neo4j. So you can connect to a database, send parametrized
queries and retrieve tabular results.

Hi Michael,
Sorry, I just reposted here. I tried to find tis post and it was not
showing up. I just recently was able to see this post again.
Anyways - I don't understand your answer. When I look up JDBC it seems
like it is a GUI for interacting with Neo4J and not a library to write
queries

I use the SDN 3.0.0 in production (I know this isn't the last version).
Basically, I have a `Parent` class (@NodeEntity) having a relationship

When I want to update the parent, I do:

Hi Jenny,
sorry that you have a hard time getting going with Neo4j spatial. Which
version of Neo4j Spatial are you using? We recently released:
0.13-neo4j-2.0.1

Hi Jenny,
yes, it's tricky, getting all pieces together to have a working database
with spatial. But it can be done.
Question is, do you want to create the app by coding everything from the
ground up (which is fun, and you learn a lot about spatial/Neo4j), or do

Did you configure conf/neo4j-server.properties to listen at the 0.0.0.0
interface ? Uncomment that line.

I have created VM (Windows Server 2012 R2) on Windows Azure and installed
Neo4j on that VM. I am able to access using http://localhost:7474 link.
When I try to access the same from my local laptop, I am not able to
access. I have created Endpoint for Neo4j on VM and also opened the port
7474.

Hi Michael,
you mean don't use dataset that doesn't make sense?
Please help me just by checking my last two queries. I'm testing my thesis
until depth of five only.
and is there no others way to speed up the traversal in cypher? maybe
shortestPath? is the only way using traversal-API?

Hi Michael,
Can you give me some news ?
Thanks

Michael,
Wow i just looked into the Traversal API docs on neo4j. Will this kind of
functionallity like the evaluater ever be exposed to Cypher commands and
intepreted ? I program Gol(lang) and Nodejs but this framework combined
with Neo4j is a good reason for start using Java ;)

Mabey something more simple like this

Had the same issue and I found that creating a dedicated neo4j user with

The steps I did to get Neo4J 2.0.1 running:

of /bin/bash

that I can query across databases.

Just use a dataset that you can reason about and check if they work
correctly.
Hard for me to be the consistency checker on your queries :)
In general if you really want to do these deep traversals you might be
better off (in terms of performance) using the traversal-API with an

Hi,
Let's assume this beginning of Cypher query, aiming to retrieve all
shortest paths (regarding knowledge) between two users:

(u1-[:KNOWS*..4]-(u2))
Besides, each User is linked to a UserProfile node in the graph
