Donovan, The project is on GIThub, https://github.com/peterneubauer/sql-import and I am right now porting it to Neo4j 1.4. However, I have limited bandwidth, I suspect it will take me some evenings to get it working properly again. Is that ok? Cheers, /peter neubauer GTalk:      neubauer.peter

I wrote this plugin. Everything works as it should (on local). I put this plugin (as web-application) on a server that is running neo4j. In order to receive the data - I'll do a GET-request to that web-applications. In web applications to initialize neo4j I use GraphDatabaseService graphDb = new

If you can cope with some limitations of Neo4j official plugin system (the biggest thing for me is a bit limited choice of responce options: it can be either collection of Nodes, or Relationships, or Pathes data, packed with JSON), may I suggest using it instead. ) In this case your DB works in

The probleme here is that there is already a running database instance (that serves the rest-request and everything else). If you put your code into a ServerPlugin or UnmanagedExtension you can in both cases get an instance of that GraphDatabaseService passed into your method that you then just

Yes you are able to do that: * if you are running in a neo4j-server you have to access the database via the GraphDatabaseService instance that is provided from the server (because the server _owns_ it) * that's why inside a neo4j-rest server you have to get access to that instance, and
