Hi, I have been trying this out, but have had a few problems:
- The current neo4j-spatial code on github cannot compile on my computer. It seems to be a problem with the dependencies in the pom.xml. I am trying out switching instead to the 1.2 release, instead of the 1.2-SNAPSHOT you used. I suspect conflicts between the neo4j-server-1.2 and the neo4j-*-1.2-SNAPSHOT in the pom. Right now the neo4j maven repository seems to be down, so my experiments will have to wait. - I got the below mentioned server to run by copying the neo4j-spatial jar directly from the maven repository yesterday (since I could not compile it myself), and found the node not added to the index. Reading the new code in the spatial plugin I see that indeed the node is not added to the layer, so this should be fixed. Of course fixing it requires I get the maven build running again ;-) - The wiki page for how to add plugins to the server does not seem to be linked to from any of the getting started with the server pages. Perhaps we should add a link there? And if necessary correct the instructions to resolve these dependency issues I'm having. I wonder if it would not be better for the server plugin to be a separate project that depends on both neo4j-spatial and neo4j-server, so that neo4j-spatial does not need to have neo4j-server as a dependency? That would make a lot of sense to me. Anyway, it is great to have a first stab at this, and if we can resolve the above mentioned issues, it should be easy to move this forward in a few interesting directions.
