Is this a current capability?

Mmh,

Neo4j Spatial implements the writing support, see https://github.com/neo4j/spatial/blob/master/src/main/java/org/geotools/data/neo4j/Neo4jSpatialDataStore.java#L217 but I have not tested it lately. Feel free to give it a spin!

The old wiki used to have instructions on how to get neo4j-spatial working in geoserver, but that wiki no longer exists. Peter, is it possible to dig those instructions out of the archives and put them somewhere?

It's in the README now, see

https://github.com/neo4j/spatial and scroll down a bit :)

Cheers,

I followed the Neo4j Spatial instructions for using Geoserver 2.1.1
but Neo4j does not show up as a Vector data source nor are there any
errors in the catalina.out file to indicate why. Now, I tried this
with an older instance of Geoserver at 2.1.0 and Neo4j shows up as a
Vector data source but when trying to save the information for the
Neo4j Spatial db file (directory) I get the following error in the
catalina.out:

Mmh,
Seems JTA is missing from the classpath. We should get an automated GeoServer test up. I can look at it next week if you remind me and raise an issue? Try to get all neo4j core jars on the class path to start with (everything in the lib folder of the distribution)?

Got everything working as far as Geoserver serving up data as either a
WMS or WFS and Quantum GIS can open up the WFS layer and show
attribution. However, the WFS-T isn't enabled because the Neo4j
Spatial database does not tell Geoserver (via GeoTools, I think) which
field is the Primary Key for transactions.

The Neo4j Spatial db that I got to work in Geoserver was built from a
shapefile using the basic ShapeImporter class.

I have also created a Geoserver data store using a Neo4j Spatial db
built from Open Street Map data using OSMImporter. This data store
loads fine but does not show that there are any geospatial layers to
be published via OGC Web Services. Is this proper behavior for OSM-
based Neo4j Spatial dbs or is this a flaw?

The osm layers should show. I can test it once I have slept a bit, tomorrow European time :-)

Weldon,
will try to set it up now. If I get it working and live to tell you,
do you have any clue how to deploy a GeoServer setup as part of a unit
test in order to automate this?

Have you ever used the Geoserver REST API? You can use it to create
data stores, publish layers, etc. The Geoserver website has examples
using curl and php. I have used the curl/REST method to publish over
two hundred layers from PostGIS database tables. The REST API is
fairly mature these days.

Hope this helps,

Yes,
That is good for testing. But we need to fire up the server with the neo4j store deployed in the setup part of the year :-)

By 'year' do you mean 'war' file?

Oh,
I meant test. Not sure if a war or some integrated startup with all GeoServer dependencies om the classpath would be the best...

The image below is a screen capture of the geoserver-trunk from Subversion on Sourceforge. To include your own data into the release configuration, you would have to have a working Neo4j Spatial instance in Geoserver complete with the workspace that contains Neo4j Spatial data store(s) and of course under the data directory the subdirectory tree containing the actual Neo4j Spatial db(s). You place the workspace into the geoserver-trunk/data/release/workspaces directory and the subdirectory with the Neo4j Spatial db(s) into the geoserver-trunk/data/release/data directory. And then follow the instructions for the Maven Building the Web Module.

I was able to solve my problem with the OSM-based Neo4j Spatial
database. I had performed the batch insert but forgot to re-index the
data. Once I did that the layer displayed immediately. Now all that is
left to determine how to enable the WFS-T on Neo4j Spatial dbs.

Great!
Let me know if you need help. I am not an expert in GeoServer but have a test running now and could factor in what you need.

In order for Geoserver to enable a WFS layer for WFS Transactional,
the layer must have a unique, non-NULL integer/long field to be used
as the Primary Key. So Neo4j Spatial is not reporting a field that
meets these requirements so that Geoserver can allow transactions on
the layer even though GeoTools would be able to edit the data
directly.

Below is an excerpt from the catalina.out file when attempting to use
WFS-T to update a feature in Neo4j Spatial via Geoserver:
