Re: [Neo4j] Neo4j Spatial - Keep OSM imports - Use in GeoServer
Craig, Thanks for your answer, I looked at this page and so, I've put those libs inside the WEB-INF/lib/ directory : - neo4j-kernel-1.4-SNAPSHOT.jar - neo4j-lucene-index-1.4-SNAPSHOT.jar - neo4j-graph-algo-1.4-SNAPSHOT.jar - geronimo-jta_1.1_spec-1.1.1.jar - lucene-core-3.1.0.jar - json-simple-1.1.jar + neo4j-spatial-0.6-SNAPSHOT.jar (and all the packages of this directory, like neo4j-spatial-0.6-SNAPSHOT-server-plugin.zip etc...). Still not working, got the same error ;) There is no hurry anyway, have a nice trip, Robin 2011/7/12 Craig Taverner > I am travelling at the moment, so cannot give a long answer, but can > suggest > you look at the wiki page for neo4j in uDig, because there we have made > some > updates concerning which jars to use, and that will probably help you get > this working. > On Jul 12, 2011 10:59 AM, "Robin Cura" wrote: > > Hi, > > > > First of all, thanks a lot to both of you for your answers, I have only > been > > able to try this yesterday, and it released me from lots of troubles. > > > > I succeeded editing the Neo4jTestCase.java file in Netbeans, as you told. > > I've got troubles to install latest JRuby release (needed for > neo4j-spatial) > > within my Ubuntu, so, I'll make this later, but it's really a good thing > to > > know considering the simplicity of use. > > > > Creating thoses databases made me realize another problem.In fact, I > > followed the tutorial about using neo4j db in Geoserver, and it appears > that > > my neo4j plugin for Geoserver doesn't work, as I always get this error > when > > trying to create a new store linking to my neo4j database. > > My database is a folder named "db1" (and "db2" for the other one), > located > > in my ~/ folder. > > > > In Geoserver, I create a new store and make it link to > > "file:/home/administrateur/db1/neostore.id" > > But each time, I got this errror : > > > >> Error connecting to Store. > >> > >> There was an error trying to connecto to store neo4jstore.

Re: [Neo4j] Neo4j Spatial - Keep OSM imports - Use in GeoServer
I am travelling at the moment, so cannot give a long answer, but can suggest
you look at the wiki page for neo4j in uDig, because there we have made some
updates concerning which jars to use, and that will probably help you get
this working.

Re: [Neo4j] Neo4j Spatial - Keep OSM imports
Another option is to run the main method of OSMImport class, which expects
command line arguments for database location and OSM file, and will simply
import a file once. This is not tested often, so there is a risk things have
changed, but it is worth a try.
Another, even easier, option in my opinion is the JRuby gem,
neo4j-spatial.rb. See http://rubygems.org/gems/neo4j-spatial
To get this running, just install JRuby from http://jruby.org, and then
install the gem with "jruby -S gem install neo4j-spatial" and then you will
have new console commands like 'import_layer'. If you run 'import_layer
mydata.osm', it will import it to a new database, which you can use. See the
github page for more information:

Re: [Neo4j] Neo4j Spatial - Keep OSM imports
Robin,
the database is deleted after each run in Neo4jTestCase.java,
@Override
@After
protected void tearDown() throws Exception {
shutdownDatabase(true);
super.tearDown();
}
if you change to shutdownDatabase(false), the database will not be
deleted. In this case, make sure to run just that test in order not to
write several tests to the same DB for clarity.
mvn test -Dtest=TestDynamicLayers
Does that work for you?

[Neo4j] Neo4j Spatial - Keep OSM imports
Hello, First of all, I don't know anything in java, and I'm trying to figure out if neo4j could be usefull for my projects. If it is, I will of course learn a bit of java so that I can use neo4j in a decent way for my needs. I'd like to use a neo4j spatial database together with GeoServer. For this, I'm following the tutorial here : http://wiki.neo4j.org/content/Neo4j_Spatial_in_GeoServer But this paragraph is blocking me : " - One option for the database location is a database created using the unit tests in Neo4j Spatial. The rest of this wiki assumes that you ran the TestDynamicLayers unit test which loads an OSM dataset for the city of Malmö in Sweden, and then creates a number of Dynamic Layers (or views) on this data, which we can publish in GeoServer. - If you do use the unit test for the sample database, then the location of the database will be in the target/var/neo4j-db directory of the Neo4j Source code. " My problem is I do not succeed keeping those neo4j spatial databases created with the tests : When I run TestDynamicLayers, it builds databases (in target/var/neo4j-db), but as soon as the database is successfully loaded, it deletes it and start importing another database, and so on. My poor understanding of java doesn't help a lot, I tried to edit the .java in Netbeans + Maven, but until then, it doesn't work, all the directories created during the tests are deleted when the test ends. Any idea how I could keep those databases ? Thanks, Robin ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
