Hi Peter,
Sure, my intent is to do an example project. I can document it (but it will
take some time). This afternoon I loaded a shapefile into neo4j. Although
the loader had printed some errors, the nodes were loaded. Tomorrow morning
I need to check if this worked and if the layer will load into geoserver.
Some notes:
I did nothing different than what is in neo4j-spatial readme at github,
except remove the older xerces jar file (the one created by neo4j-spatial).
One thing I noticed was that I've built the 2.0.0 SNAPSHOT version of
neo4j-spatial and I was using neo4j 1.9.
I've fixed it in the neo4j side (downloading the pre-compiled zip from
github), but not yet at geoserver side (tomorrow morning I will!).
Finally, I did the shp import as in the example. Like that, I couldn't use
neo4j from java while the server was running. Is this the default behavior?
Also, is there some way to load shapefiles into the running server? (It
would be nice to load them and still have access through rest api).
As soon as I finish these tests, I'll report the conclusion and
documentation.
Cheers,
Rodrigo C. Antonialli
