Have you changed the port numbers used by each server? If running multiple 
instance on the same server, you'll need to make each port unique. 

In neo4j-server.properies, check:
org.neo4j.server.webserver.port=7474

Andreas

Re: [Neo4j] multiple servers on Mac

Ah, sorry Gengo, I wasn't reading carefully. At the moment, the install 
procedure isn't clever enough to accommodate multiple instances running on the 
same machine. After making the appropriate configuration file changes, you'll 
also need to differentiate the launchd plists which are created.

Just a sec, I'll run through the procedure and post back here.

Re: [Neo4j] multiple servers on Mac

Hi Gengo,

I've modified the neo4j start script and the launchd plist template to support 
installing multiple servers on Mac OSX. Would you be interested in trying the 
patch? I've attached it for your consideration. Just expand the archive into 
each of your neo4j install folders. The tarball contains a patched neo4j script 
which appends the configured port to the launchd name. To complement that, the 
plist template has a placeholder for the modified name. 

Let me know how this works for you, and I'll look into getting this included in 
the next production release.

Best,
Andreas

ps. Oh, with this patch, you should be able to simple use `neo4j install` after 
making changes to the port numbers. 
pps. Don't use this on a production system. This has obviously not gone through 
proper QA.

Re: [Neo4j] performance guide

Hi Linan,

These are good questions. I am currently following a similar approach to 
characterizing the performance of basic graph operations, and then also simple 
graph algorithms on various shapes of graphs. My initial investigation is on 
small graphs on my laptop, but this weekend I'm testing large graphs on Amazon 
instances (large, as in  500 million nodes).

I'll post the summary of my findings from this weekend, then continue to 
elaborate on the operations and different server configurations.

 below is my guess, from fastest to slowest, feel free to correct me
 and add more.
 
 1, Read id of a node/relationship.
 2, Read property value of a node/relationship.
 3, Set property value of a node/relationship.
 4, Retrieve a node/relationship by id.
 5, Create a new node/relationship.
 6, Retrieve a node by external id from node index.
 7, Retrieve all relationships of a node.
 8, Retrieve a certain subset of relationships of a node from

Re: [Neo4j] Easy to switch from Embedded to HighAvailability graph?

2011-08-08 Thread Andreas Kollegger

Hi Raffi,

That's a very sensible approach to scaling up the capacity of your system. 
Because you are embedding Neo4j, you can simply switch to using 
HighAvailabilityGraphDatabase instead of EmbeddedGraphDatabase, as described 
here: http://wiki.neo4j.org/content/High_Availability_Cluster

You will first need to configure the Zookeeper cluster, and each Neo4j HA 
instance. 

Do you anticipate continuing to host each application within Tomcat? What will 
you use for load-balancing?

Best,
Andreas

 understand that there will configuration updates (ZooKeeper, etc), but is
 there any material impact to the data or special considerations before
 making the switch? Will the database auto-balance/shard in the HA
 configuration, or does that have to be done manually before the system in

Re: [Neo4j] Easy to switch from Embedded to HighAvailability graph?

2011-08-08 Thread Andreas Kollegger

Sorry for the delay on writing up that material. I had a small window of lab
time to work on such things, which quickly filled up with other tasks. It is
on my backlog, which fits in with general operations support that I've spent
some time working with here: https://github.com/akollegger/ha-ops

All the material there needs to be updated to reflect the current release. I've
updated ruby and associated gems used for simulating a cluster on a single
machine. The variations are:

- run a cluster by configuring multiple instances to run on the same machine
(scripted with Ruby and bash)
- run a simulated cluster using virtual machines

Both of these use Neo4j server. I'll augment with an embedded example, then
finally a mixed embedded/server deployment.

I expect to have some free time later this week to work on all this.

Thanks for your patience.

To use webadmin with an HA cluster running embedded, you would configure one of 
the machines to run the full Neo4j Server, but configured to run in read-only 
mode. This would result in a pure monitoring instance, which would allow you to 
check on the database and run queries using webadmin. Later today, I'll create 
a sample application that does that, then send you the detailed steps involved.

Hello,

Each node in the HA cluster will have a webadmin available. If you're running

Are you just setting up for testing, or is this a production environment?

Re: [Neo4j] How to run webadmin for high availability neo4j custer?

2011-08-01 Thread Andreas Kollegger

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 Zookeeper
cluster is used to coordinate the activity of the Neo4j data nodes, while all
replication data goes through our own HA protocol. Zookeeper has a shell tool
that could be used to check on it, but otherwise we don't have specific tooling
for monitoring of the coordinators.

Do let us know if you have any questions about the operations that seem like
they could use more documentation. And, when you're ready to go into
production, drop us a line to talk about a commercial license, unless you're
just deploying a full open-source stack for your application.

Best,
Andreas

The HA cluster is for testing initially. If everything works fine, we'll need
to put them in production. if you have detailed production installation
guide, that will be great. It appears that there are additonal setup
procedure for the Neo4j coordinators. We also need similar weadmin or other
monitoring tools for production HA as well.

[Neo4j] Vancouver Graph Meetup - Next Wednesday

2011-07-20 Thread Andreas Kollegger

Graphistas of the North,

Join us at Mozilla Labs in Vancouver next Wednesday, the 27th, for a graph 
meetup with the inimitable Peter Neubauer[1]...

Every graph starts with a single node, then branches out. So, we'll start with 
a general introduction to graphs, discussing the concepts, available 
technology, use cases and broader topic areas. We'll get to know each other 
along the way, because as graphistas we never shy away from a good tangent. 
Bring your questions and graph challenges; Peter is always up for a good 
technical conversation. 

Details are on the meetup page[1]. 

Cheers,
Andreas

[Neo4j] Seattle Graph Meetup - next Wednesday

2011-07-20 Thread Andreas Kollegger

Seattlite Graphistas,

No need for a border crossing next Wednesday the 27th to talk about graphs, 
because we'll be meeting in Seattle, making an appearance at the monthly Hadoop 
meetup[2].

After a brief introduction to graph databases for the uninitiated, we'll review 
the new features of the Neo4j 1.4 release. As always, there'll be opportunity 
for tangential discussions, both at the meetup, and afterward when everyone is 
invited to join in for drinks and casual conversation. Got questions, or 
feature requests you'd like to make heard? We'll be listening. 

I look forward to seeing you there. 

Cheers,
Andreas

[Neo4j] Adding nodes to the Meetup Graph

2011-06-27 Thread Andreas Kollegger

Good Monday to you all, Graphistas,

Just some quick news about worldwide meetups...

Vancouver:

We're pleased to announce that a Meetup group is establishing itself in 
Vancouver[1], with the help of our good friend Paddy Fitzgerald. Anyone in the 
area, please join us for the kick-off meeting in July. 

Rome?:
There've been some rumblings about interest in a Rome meetup. Are there Romans 
on the list that would concur? 

London:
The much anticipated A Short Tutorial on Dr.Who (and Neo4j) is this 
Wednesday. Sign up on Skillsmatter[2]. Ian and Jim will be confidently 
navigating the twisty time-space continuum of Dr.Who using graphs. 

Berlin:
The first meeting of Graph Databse - Berlin will be tomorrow at C-Base[3]. 
Michael Hunger will be leading a quick intro to graphs, then following any 
tangents that are of interest. Bring your questions to keep Michael on his 
toes. Oh, and of course there'll be free beer.

Silicon Valley:
The first round of meetings in the San Francisco bay area[4] were quite 
successful and fun. It was a delight to meet you all. New meetings for July 
will be posted this week. 

Seattle:
Finally, Seattle will be meeting for the first time at the end of July. If 
you're near that area, drop by to meet the community and enjoy a beer on us. 

Cheers,
Andreas

[Neo4j] Thanks Marko, Jive Friends

2011-06-23 Thread Andreas Kollegger

On behalf of the lucky roomful of people in the Silicon Valley who attended 
last night's Graph Minicamp, I'd like to thank Marko for a great walk-through 
introduction to graph algorithms. And also, thanks to the packed room that 
showed up last night.  Marko's progressive exploration of graphs was engaging, 
and your questions and discussions really kept him on his toes.

Marko's headed out to Chicago now for WindyCityDB[1], where he'll be delivering 
an even more intense (really? like mind-bending and yoga at the same time?) 
full day Graph Bootcamp. If you're out in Chicago, there's still time to sign 
up for that[2]. If anyone is interested in having a mini- or full bootcamp in 
your area, let me know and I'll see what we can arrange with Marko. 

Lastly, a shout-out to the good people at Jive[3] for hosting us in Palo Alto.

Cheers,
Andreas

Re: [Neo4j] Scala/Lift as neo4j frontend

2011-06-21 Thread Andreas Kollegger

Hi Manav,

Embedding Neo4j in a Scala/Lift application is a perfectly sensible thing to 
do. The biggest trade-off is missing the web-based administration for the 
database. Are you thinking about using the Lift as the user application, or 
just as an alternative for exposing domain-specific interface over the network?

Best,
Andreas

On Jun 20, 2011, at 1:39 PM, Manav Goel wrote:

 Hello
I have been reading about Scala recently that it uses a JVM and
 java libraries can be used very easily in scala. This got me thinking if I
 can use Scala/Lift (or maybe Groovy/Grails)as frontend and neo4j backend as
 I can simply create an API of my database code and simply call it in Scala
 without using REST,simply in embedded neo4j.
 Is it advisable to do such thing?
 Somehow I am not able to make up my mind regarding java as my frontend(Noe4j
 is decided by the way) or using REST API.It looks too restrictive(Correct me
 if my thinking is wrong)

Hi, all.

A couple index framework questions:

1) There does not seem to be a built-in API call to determine whether
or not a node exists in a specific IndexNode. After looking into the
index structures with Luke (the must-have tool for anyone working with
Lucene), it appears that each node has a virtual field named _id_ that
could be used in with index.get(_id_,nodeID) to do this check. Is this a
reasonable approach? Can we count on the _id_ field name being consistent
in future versions of Neo4J

2) The remove(node) method is supposed to remove the node from the
index. In the case where the node wasn't in the index, what it appears to
do is actually *add* the node to the index as an empty document. If it was
in the index, it deletes all of the field values except the _id_ field but
leaves the node (document) in the index. This seems like it will lead to
ever decreasing performance as these ghost nodes or ghost documents
accumulate.

We are testing w/1.4M04, if that matter.

Thanks,

Rick

Re: [Neo4j] Introducing Graph Database - San Francisco

Saikat,

Hm. It seems that meetup.com limits me to being the organizer of 3 meetups. You 
can create the group and I'll join up, then send you the badge and set up the 
sponsorship. Or wait, I'll just attach it. 

The pattern I've been using for the group name is graphdb-city name. I'll 
help get all the setup done if you create the group first.

Re: [Neo4j] How to embed neo4j to OSGI env without spring?

2011-06-01 Thread Andreas Kollegger

Hey,

The Neo4j libraries should be usable within OSGi, though we're a bit lax in 
keeping on top of that. The best approach would be to use one bundle to 
instantiate the database and advertise the reference as a service for use by 
other bundles. 

Cheers,

Re: [Neo4j] question about remove and iterate in same transaction

2011-05-24 Thread Andreas Kollegger

Hi Jose,

Perhaps the event framework[1] would suit your purpose. The 
TransactionEventHandler [2] includes operations for intercepting a transaction 
before it is committed.

Otherwise, to intercept the Node.delete call itself, you'd have to look into 
using AOP.

Re: [Neo4j] question about remove and iterate in same transaction

2011-05-24 Thread Andreas Kollegger

Aspect Oriented Programming[1]  (AOP) lets you decorate classes and methods 
with extra behavior. Assuming that you're working with Neo4j in an embedded 
application, you'd use a library like AspectJ [2][3] to add advice to the 
Node.delete (actually the NodeImpl class) to perform your logic before the 
actual method is called, giving you the opportunity to *not* call the actual 
method. 

Personally, I always find it a bit scary to use AOP, but when it works it seems 
magical.

[Neo4j] [ANN] Neo4j 1.4.M02 Kiruna Stol - Chugging Along

2011-05-13 Thread Andreas Kollegger

Hi peeps,

Another two weeks have flown by since the first milestone of “Kiruna Stol”, so 
it’s time for a new milestone release. 1.4.M02 brings mostly performance 
improvements, in the form of dependency updates and internal changes, but also 
new indexing operations via the REST API.

NOTICE: This version introduces a non backwards compatible upgrade in the 
format of the index store. Always backup your data and do not try out on 
production settings before testing.

Lucene upgrade:
The most prominent change is probably the upgrade of Lucene to version 3.1, 
allowing for significant speedups prominently in lookups, with index writes 
seeing some measurable benefit as well. Depending on your use case, you will 
notice up to twice as fast queries, reducing what was a prominent bottleneck.

Note, again, that Lucene 3.1 introduces a store format that is backwards 
*incompatible* with 3.0.1, meaning that after you upgrade to M02 you will not 
be able to get your index data back with previous Neo4j versions.

Additions to the REST API:
The REST API so far has been left wanting regarding the available index 
operations. This milestone exposes all the Neo4j specific index operations 
users of the embedded version enjoy, enabling deletion of indexes, complete 
Lucene queries and setting of default keys for indexing operations.

Append-only logical log
Then there’s the new default implementation for how things are written to the 
logical logs. Instead of a memory mapped file there’s the append-only file 
backed by a buffer. This will reduce the bottleneck that is the logical log, 
mostly apparent in small transactions. We’ve measured a throughput improvement 
of up to 20 times. Whereas this is an improvement which will benefit any setup 
it will make its most exquisite appearance in the server and when working with 
the REST API.

We would love to hear about your experiences with the new milestone. Since 
performance improvements are difficult to quantify given the multitude of use 
cases, your feedback will be even more useful than usual.

Read more in the official blog announcement via DZone, and vote us up if you 
like it: http://www.dzone.com/links/neo4j_14m02_enhanced_indexability.html

Re: [Neo4j] Self-referencing relationships

2011-04-26 Thread Andreas Kollegger

Hi Shaunak,

As you've noticed, self-referencing nodes have been considered before, and I 
remember being perplexed by the lack when I first became a Neo4j user. Changing 
the support is simple enough, but there was obviously a conscious design 
decision. Why? 

Anecdotally (and wiser, longer memoried minds should correct me), 
self-referencing nodes lead to more trouble than they're worth. So they're 
considered an error because there is more value in being alerted that you just 
related a node to itself, then there is value in the few cases where you 
absolutely must have them. Being a database, the decision has been to err on 
the side of avoiding problems, even at the cost of some convenience. 

An approach that could allow for intentional self-referencing, while still 
protecting against accidental self-references, would be implement an explicit 
Node.relateToSelfAs(RelationshipType type). 

What does you model look like, that you expect to require self-referencing? 

Best,
Andreas

Re: [Neo4j] Self-referencing relationships

2011-04-26 Thread Andreas Kollegger

I've wanted to do similar tracking of paths within a graph, but am not clear
about your approach. Were you creating new relationships between each node
directly to represent an event? I suppose you'd have to add the user id and a
sequence number into each relationship to keep the tracking distinct and
preserver order. Which would work, except for repeats to the same node. Instead
of sequence numbers in the relationships, you could just use a sequence of
events.

I tend to try to keep distinct concepts within the graph separate. Like
possible paths (a graph of possibilities) vs actual paths (which are trees
because they are a sequence of events). With buttons, I would first create the
graph of buttons with possible paths:

A - B - C - {wherever}

Then track each user traversal by referencing those nodes in sequence:

User1 -- event1
event1 -clicked- A
event1 -next- event2
event2 -clicked- B
event2 -next- event 3
event3 -clicked- B
event3 -next- event4
event4 -clicked- C
etc...

Subsequent users would either increment counts along that path or create new
branches when they diverge.

Cheers,
Andreas

Run this over a few 10's of thousands of users (incrementing counts), and
a few dozen buttons, and you can start to find things like:

This sequence of button presses is the most common path for users through
our prouduct.

If a user is on button B, it is pretty likely they'll click it again.

The group of users who are based in California tend to click buttons on
the left side of the screen, while the ones in Massachusetts tend to click
buttons on the right side of the screen.

There may have been other ways to do this modeling, but the way I
implemented it really needed self referencing relationships to count all
the [then clicks] relationships, not just the ones that move to new
buttons.

Re: [Neo4j] Neo4j on OSGi

2011-04-25 Thread Andreas Kollegger

Hi Nicolas,

I had done some work with embedding an OSGi environment within the server to 
host plugins, hoping to slowly modularize the server in a sensible way. But 
that code has been pulled out, as we opted for the Java ServiceLoader approach 
for plugins.

When deploying into an OSGi environment, I've approached it as embedded 
development. The server only adds the REST api (which isn't needed when talking 
directly to the database), and the Webadmin (replaced by the OSGi webconsole. 
well, except for visualization). We've been relaxed about good OSGi discipline 
in the server bits, because it seemed like OSGi development is embedded 
development. 

Are you developing an application in OSGi, or are you interested in replicating 
the server (including REST+webadmin) in OSGi?

[Neo4j] Washington DC Release Party

Graphistas of the greater Washington metro area,

As mentioned in the release blog, we'll be getting together at The Front 
Page[1] next Tuesday at 7:00pm. The Front Page is right near the Dupont Circle 
metro stop on the red line. I'll be the guy wearing the black ball cap with a 
Neo4j logo. 

While I'm not saying that the other meet-ups will be lame, they won't have me 
as a host, which limits how cool they can really be. 

Reply to this thread, or contact me directly if you have any questions.

Re: [Neo4j] Cron job inside embedded neo4j

2011-03-24 Thread Andreas Kollegger

Hi Saikat,

The embedded graph database does not have such a facility. You'd have to manage 
a timer thread yourself or use perhaps Quartz[1] for sophisticated job 
scheduling.

Cheers,
Andreas

 Folks,
 I was wondering if there's a way to simulate the notion of a cron job inside 
 embedded neo4j, I nerd to have a way to periodically update a certain

[Neo4j] Neo4j 1.3 Abisko Lampa M05 - Preparing for arrival

2011-03-24 Thread Andreas Kollegger

Hello everyone,

Another milestone has arrived, bringing a new webadmin UI, extended server 
extensions and improvements on the Windows side of things. For a thorough 
description of the changes present, as always, refer to the official blog post, 
available at:

http://blog.neo4j.org/

A new interface awaits the users of the Web Administration Console for the 
Server component. The classic tabular view is present alongside a new 
visualization engine that makes navigation of the graph data easier. Also, 
appealing to your inner geek, keyboard shortcuts make their first appearance, 
where you can now press “s” from any page and have the data browser bar 
immediately available.

For the Windows users out there, you will be relieved to know that this 
milestone levels out any differences between your platform and what Mac and 
Linux users have been enjoying so far. The full backup feature now works 
flawlessly, courtesy of a custom locking mechanism and a filesystem abstraction 
that enables backup operations and the High Availability component to operate 
as smoothly and as fast on Windows as on the rest of the supported platforms.

As always, there is a host of bug fixes and less notable improvements scattered 
throughout the various components, many of which are a direct result of the 
feedback this community provides.

Only one week remains until the GA release of 1.3 “Abisko Lampa” and we are 
hard at work trying to make this the best release so far. Until then, keep 
those ideas coming people!

Cheers,
Andreas

Re: [Neo4j] Neo4j OSGI bundle

2011-03-12 Thread Andreas Kollegger

Hi Nicolas,

We should be using the maven-bundle-plugin on the individual components, but 
I'll have to check to make sure that they look right. The org.neo4j:neo4j 
artifact is just a dependency jar, so it doesn't itself have anything to 
export. That's why Tobias suggested grabbing the individual dependencies. 

I'll go try out a fresh pax-create-project to see what's up.

 Only the bundles that org.neo4j:neo4j depends on exports packages. I

 can depend on org.neo4j:neo4j and use those packages. Is that the
 appropriate way? I have little OSGi experience (other than cursing over it
 when it fails the build process because you need to very explicitly declare
 which packages to include).
 
 If that would solve things for you we will make sure to make those changes
 for the next milestone. In the meantime you can directly depend on the
 bundles org.neo4j:neo4j depends on, you are probably interested in at least:
 org.neo4j:neo4j-kernel
 org.neo4j:neo4j-lucene-index
 But perhaps these as well:
 org.neo4j:neo4j-management - JMX support
 org.neo4j:neo4j-graph-algo - Graph algorithms, such as shortest path
 org.neo4j:neo4j-com - Communication support, this includes the online-backup
 server, and the bases that HA depends on
 org.neo4j:neo4j-ha - High availability support for Neo4j
 You might also want to be nice to us and have Neo4j send a ping to us every
 day, letting us know how many people use Neo4j:
 org.neo4j:neo4j-udc
 
 Please let us know how this works out for you, and if there are any
 problems. We have only done casual testing with OSGi, so any feedback is
 much appreciated.

 Hi,
 
 I'm planning to use Neo4j under OSGi framework. Because org.neo4j:neo4j

 Unfortunatelly, the bundle doesn't export any package so it's quite
 unuseful for me as my own bundle can't import them.
 I guess, at least neo4j bundle should have Export-Package directive in
 MANIFEST.MF file.
 Do you think these headers could be added in the next snapshot ?

Re: [Neo4j] Neo4J Plugin

2011-03-09 Thread Andreas Kollegger

Hi Francois,

There is not direct support for doing that with a ServerPlugin. It is possible 
to write a custom Representation implementation that would help, but we haven't 
documented that approach. 

An alternative at the moment would be to write an unmanaged extension: 
http://docs.neo4j.org/chunked/snapshot/server-unmanaged-extensions.html

The downside is that is rest-api specific. While the ServerPlugin 
Representation will work across any transport which we add to the server 
(currently only REST, but other wire protocols would be possible).

Best,
Andreas

Re: [Neo4j] Different build errors

2011-03-08 Thread Andreas Kollegger

Hi Nolan,

Sorry about that. The graphdb components needs to be built without any external 
repository dependencies. Unfortunately JBoss does not sync netty with maven 
central (some JBoss stuff does, though). 

This next milestone release will replace that dependency with a third-party 
packaging which is available on maven central. 

Best,
Andreas

 Yes, actually, it just did for me. I just blew away my ~/.ivy2, my ~/.m2 
 and tried again, getting the update failures. Adding the JBoss 
 repository helps.
 
 Now I'm getting errors resolving org.neo4j.neo4j-spatial 0.5-SNAPSHOT. 
 Is it not published to the snapshots repository?
 
 As an aside, I'm not sure why I'm having so many local repository issues 
 with these projects. Other projects just seem to work, but the org.neo4j 
 projects seem to require me to blow away my .m2/.ivy directories 
 regularly. I'm not sure if that's a consequence of me combining Maven 
 local repositories  and my Ivy cache, but it definitely seems to behave 
 differently than every other project I've built locally.
 
 Anyhow, I'm rebuilding the latest Git checkout and will see if the old 
 errors persist, or indeed if I can now fetch the right dependencies.

Re: [Neo4j] Different build errors

2011-03-08 Thread Andreas Kollegger

Interesting. I've never used the libraryDependencies approach for specifying 
dependencies. What's the advantage? I'll have to read up about that.

By the way, maven-central has been down for part of today, and the JBoss 
repository has been super-flaky as well. 

For reference, my working test sbt project looks like this...

import sbt._

class Neo4jTrialProject(info: ProjectInfo) extends DefaultProject(info)
{
  //
  // Repositories
  //
  val jboss_bleh = fix-this at 
http://repository.jboss.org/nexus/content/groups/public;

  //
  // Versions
  //
  val NEO4J_VERSION = 1.3.M03

  //
  // Dependencies
  //

 OK, here's what I figured out yesterday. No matter what I do in SBT, I 
 can't get the neo4j-kernel dependency. Here's my project configuration, 
 or at least the relevant parts:
 
 class Project(info: ProjectInfo) extends DefaultProject(info) {
 
   val mavenLocal = Local Maven Repository at 
 file://+Path.userHome+/.m2/repository
 
   val osmVersion = 2.5.2-RC1
   val osmURL = 
 http://downloads.sourceforge.net/project/travelingsales/libosm/+osmVersion+/;
 
   val databinder = databinder at http://databinder.net/repo/;
 
   val neo4JSnapshots = Neo4J at http://m2.neo4j.org/snapshots;
   val jBossRepository = JBoss at 
 http://repository.jboss.org/nexus/content/groups/public;
 
   val neo4JVersion = 1.3.M03
 
   override def libraryDependencies = Set(
 net.databinder %% dispatch-http % 0.7.8,
 net.sf.travelingsales % osmlib % osmVersion from 
 osmURL+libosm-+osmVersion+.jar,
 org.geotools % gt-main % 2.7-M3,
 org.neo4j % neo4j % neo4JVersion,
 org.neo4j % neo4j-kernel % neo4JVersion,
 org.neo4j % neo4j-spatial % 0.5-SNAPSHOT
   )++super.libraryDependencies
 
 }
 
 Regardless of whether or not I specify the kernel dependency, it is 
 never fetched. I do, however, get the neo4j-kernel-test jar. This is 
 after multiple iterations of removing and recreating all caches, 
 lib_managed/ and target/.
 
 If I pull the kernel jar from my local cache, placing it in lib/, 
 everything works as expected. But something in SBT's dependency 
 resolution breaks on Neo4J. I've not experienced this issue before in 
 over a year of using SBT, so I'm not sure where to go from here. The 
 placement of the kernel jar in my project is a good temporary solution, 
 but I'm trying not to commit binary artifacts to my repository unless 
 absolutely necessary.
 
 Thanks.

Re: [Neo4j] Different build errors

2011-03-05 Thread Andreas Kollegger

Hi Nolan,

The org.neo4j:neo4j artifact is just there to pass through transitive 
dependencies on the official distribution of neo4j libraries. You'll need to 
be sure to include transitive dependencies, or specifically include each 
artifact.

What build tool are you using: maven, sbt, ant, gradle, or other?

 OK, picking up my Neo4J project again. Updating the dependency to
 Spatial 0.5-SNAPSHOT seems to have resolved the issue wherein I was
 having M01 jars on my classpath despite using the M03 branch. Now I'm
 getting a different error.
 
 References to any contents of org.neo4j and subpackages are all unresolved.
 
 I poked around in my lib_managed directory and noticed some oddities. I
 do have a neo4j-1.3.M03.jar, but it's only 16K. Uncompressing it gives
 me a pom.xml, MetaINF/ but no classes. Should it be this way?
 
 I have a neo4j-kernel-1.3.M03-test.jar, but no neo4j-kernel jar. Should I?
 
 It looks like my dependency retrieval process isn't downloading
 something despite my specifying the dependency as documented on the
 downloads page, or the jar isn't being built correctly.
 
 Thanks.

Re: [Neo4j] Different build errors

2011-03-05 Thread Andreas Kollegger

Did `sbt update` fail? Because it did for me when I just now set up a sample 
project, failing to find org.jboss.netty#netty;3.2.1.Final, which I believe 
is only available from the JBoss repository. 

We should look into making that an optional dependency since it isn't available 
from maven central and probably isn't needed unless you're using 
HighAvailablity. 

For now, you could either include the JBoss repository -- 
http://repository.jboss.org/nexus/content/groups/public -- or skip the Neo4j 
dependency jar, instead specifying each individual artifact.

Re: [Neo4j] Can anyone compile the latest Neo4J Spatial?

On a fresh and clean Ubuntu VM (after installing java, maven, git, etc), I just 
cloned neo4j-spatial and tried `mvn clean install`.

During the build, I noticed a few these scattered about:

Feb 27, 2011 11:58:26 AM org.geotools.map.MapContent finalize
SEVERE: Call MapContent dispose() to prevent memory leaks

But ended up with a successful build. No failures, no errors.

Re: [Neo4j] Forums ?

Hi Emilio,

That has come up in conversations before, but we've stuck with just using the 
mailing list. While not a forum, google-groups is a good compromise because it 
is nicely searchable, web or email accessible and easy to manage. 

What does the list think? Is it time to to move on from beloved mailman? 
Perhaps to a Facebook group? (Kidding, I'm kidding)

Re: [Neo4j] Can anyone compile the latest Neo4J Spatial?

To be thorough, what does your settings.xml look like, and what do you have 
MAVEN_OPTS set to? Are you using any proxies for maven repositories? Are you on 
your own network, etc?

And, while we're at it: `java -version` and `uname -a`

There must be a subtle SNAPSHOT artifact problem, is all I can think of.

Just for a sanity check, do you have a clean VM you could spin up and try to 
build from?

About M2, the neo4j version scheme has changed, so 
neo4j.version1.3.M02/neo4j.version would be the thing to try. Oh, and 
changing neo4j-server dependency to match version1.3.M02/version.

Sorry this is so frustrating to track down.

If I can replicate your setup maybe I can replicate the problem.

 People keep saying things about Neo4j M2, but the pom.xml dependency is

 work as that doesn't resolve.
 
 Maybe someone would like a local SSH account? Not sure what else to try.

 I have changed a character from your example.
 Any idea?
 where can I locate your ServerPlugin.java file?

Re: [Neo4j] ServerPlugin example GetAll failed to load

Hi again,

So, it looks like the verifyName() complaint is about the name containing 
characters that aren't URL encoded. 

And, sorry, you asked for the source to ServerPlugin.java. That's here:
https://github.com/neo4j/server/blob/master/server-api/src/main/java/org/neo4j/server/plugins/ServerPlugin.java

Cheers,
Andreas

Re: [Neo4j] Can anyone compile the latest Neo4J Spatial?

OK, that looks so incredibly normal. Um... hm.

Huh, I just noticed that you did `mvn install` after the git clone. I always 
reflexively run `mvn clean install`. I'm cleaning my VM, blowing away the home 
directory, then re-trying with that. 

Hold please.

 People keep saying things about Neo4j M2, but the pom.xml dependency is
 still M1. Could that be the issue? In any case, changing to m2 doesn't
 work as that doesn't resolve.
 
 Maybe someone would like a local SSH account? Not sure what else to try.

 Hopefully I can tell you tonight, otherwise tomorrow how that works,

 The one process you'll see open in this transcript is a web app. It has
 nothing to do with Neo4J in anything other than it hosts its jars in its
 dependencies. The database is not even used at this time and, indeed,
 the exact same behavior happens if it isn't running.
 
 My next question, does someone have a development dependency hanging
 around in their local m2 repository that I don't? When you've verified
 that you can build a clean tree, you've first backed up ~/.m2 and
 removed it? In any case

Re: [Neo4j] Can anyone compile the latest Neo4J Spatial?

Alright, so that worked just fine. Last thing I can try is reducing the memory 
on my VM to just 1G. But, I can't otherwise think what could be wrong.
