Hi, guys.
I try to compile neo4j from sources.
I execute following commands and got some error messages.
How can I fix it?
git clone https://github.com/neo4j/community.git
cd community
mvn

Nikolai,
what JDK are you running?

So,
now, with another merge from Toni, you should be able to build

Could you please set your JAVA_HOME pointing to the JDK not the JRE?
That should help. I wonder how it would compile things w/o a javac :)

Nikolaj,
it seems you are on a JRE, not a JDK, which you need to compile java
programs. Try installing
apt-cache search jdk
apt-get install sun-java6-jdk
Does that work?

Request is working like a charm and is fast (around 6 objects are checked
in my 2M node 6M rel DB). I have to check the result with the corresponding
RDBMS KPI.
Thanks again !
I definitively have to take more time to learn Gremlin !

Hi,
I'm relatively new to graphs and Neo4j but I have gathered a list of
questions I hoping this community can answer or point me onward towards
them.
1. Typed edges
- What is available in Neo4j to tackle semantics (as in hierarchical
structure of edge types)
- What are the best practices when
We're already on it. Looking through the causes for that issue and will keep
you and everyone else informed.

Hi, Stefan.
FWIW, we use Neo4J for time series data, at reasonably high volumes of
near-real-time storage. What storage rates are you looking for/volume of data

Hey Graphistas,
there is a new article on NOSQL databases on InfoWorld. The part for Neo4j is
badly researched. If anyone of you thinks he could add some useful information
for the reader, please do so in the commenting section.
Thanks so much

Hi everybody,
I found [1] in the mailing list archive. I'm an eclipse rcp developer,
too and thinking about using Neo4J in an RCP application (License:
EPL) .
Are there any news of the licensing problem?
Thank in advance

Hi!
EPL-licensed software can't be combined with GPL-licensed software, so
you'll need a differently licensed version of Neo4j. Get in touch with
Neo Technology to find a solution for your case!

Hello.
Are nested transaction supported?
From what I'm testing here, it looks like unless I specify .failure() on the
nested transaction, before it reaches .finish() the transaction is
considered to be successful (even if I didn't call .success() on it). Though
if I do call .failure() then the

Perhaps we can also add to this enhanced API:
* creation of nodes and rels with a initial map of properties, with optional
auto-indexing of some of those properties

* some more that I

sounds like fun. Looking forward to get a look at this

Hi,
i'm getting the followed stack trace after trying to delete the
relationships of a node, followed by the delete of the node (the goal is to
remove the node from the store, which must have no relationships, before
doing that).
org.neo4j.kernel.impl.nioneo.store.InvalidRecordException:
Good points and worth adding.
Let me first finish the work I am doing now, which implements the current API
and adds some methods that mirror the current API, then we can start looking at
making things even niftier.

Right now I have it in org.neo4j.collections.graphdb and

separate package and its own repo.

I'm sad to say that there was a bug in BatchInserter in M04 and M05 which
could create some invalid relationship records. Is it a critical data set or

What is critical on my dataset is to keep it updated at runtime, that's why

How can i solve that issue?

I think this raises an important point:
so it looks like, HA is better than using neo4j server then , but I thought
they were both using the same way to access data, via URI and weird messy
stuff :)
You can use HA whether you embed Neo4j in your process or whether it's embedded
within the
Just start from a fresh database with 1.4 and you wont run into this

Hello neo4j comunity,
I want to create a plugin in netlogo
http://ccl.northwestern.edu/netlogo/to access neo4j database.
In this future extension of netlogo (java simulation program) i try to write
custom function which help to create, delete, traverse a graph stored in an
imbedded neo4j database
Why would you then use REST after all?
If you want to decouple netlogo from the core Neo4j API, feel free to write a
Facade that effectively encapsulates the Neo4J API publishing only what you
need and only in the API format you want to support.

sorry that it took so long, I fixed the issues with the plugin:
There were two of them - a jar-dependency that got removed around 1.4.M05 and
the refusal of Auto-Indexes to be deleted.

Javier,
I quickly tried it with curl, escaping the space to %20 and the forward slash
to %2F worked just fine.
Please note, that in your examples the forward slash was never escaped:
my example is a/b c for both key and value.
ADD:
curl -i -H Content-Type:application/json -X POST -d
I'm so sorry. The problem was a default value in a Python library for
URL encoding.
Thank you.

I have two projects. One is full-on J2EE using Glassfish. The other is
Servlet based, using Tomcat.
At this point I am not using Spring or Guice - the only injection I get is
the standard J2EE injection for my beans.
