geoserver plugin error when creating new store

[mwmitchell]

Hi,

I am able to get the geoserver plugin installed, and geoserver displays the neo4j-spatial data store option. However, when I configure a new data store and attempt to save, nothing happens. If I navigate to the data source listing in geoserver, I don't see my new neo4j data source. When I try to create again, I get this:

Error creating data store, check the parameters. Error message: Unable to lock store [/Applications/GeoServer.app/Contents/Resources/Java/neo4jdb/neostore.relationshiptypestore.db.names], this is usually caused by another Neo4j kernel already running in this JVM for this particular store

I've tried this on an empty directory, and an existing neo4j-spatial index directory.

Also, sometimes a stack trace is displayed in geoserver after clicking "save":

same question ,wait for peter's answer. @peterneubauer

[peterneubauer]

Mmh,
I recently tried downgrading GeoTools and put Neo4j under GeoServer. For me that is working, however, there seems to be a GeoServer bug preventing layers getting served correctly. Will keep you updated.

[ventlam]

I tried the geoserver 2.2 RC3,still unable to view the layer in database.

[peterneubauer]

Is that one on Geotools 8?

@craigtaverner did you ever hear from the Geoserver guys about the error we
are seeing?

I had check out the output log of tomcat,still can't work these out.Is there any version (older)can work with GeoServer ?I will appreciate to know about that. @peterneubauer

I just had the same problem as @mwmitchell (same stack trace). Solved it by changing my dbtype (in new store > "Postgis Database") from "postgis" to "postgisng".
I didn't have the link "Postgis Database NG" in the list : "Vector Data Sources" (from "New Data Source" page).

[doublebyte1]

Thanks you so much, I've been banging my head in the wall for a while, to make this work!

[WuChengbin]

Does this bug fixed on GeoServer 2.13.0 ?
Neo4j 3.3.5 + GeoServer 2.13.0 still unable to load layers in the neo4j db.

We are upgrading our Geoserver from 2.11.2 to 2.15.2 and having the same problems.
I tried to do as you explaned but when i changed from postgis to postgisng nothing happened.
We are trying to use the same data_dir and just change the data stores.

I'm busy with this issue also. I will try to rebuild Neo4J with the same version of the GeoTools I have in my rebuilded Geoserver 2.17-snapshot.

Now I do put in the Neo4J server plugin builded from the Neo4J source:
neo4j-spatial-0.26.2-neo4j-3.5.2-server-plugin.jar
