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 use. Here are some examples: http://docs.neo4j.org/chunked/snapshot/server-plugins.html http://docs.neo4j.org/chunked/snapshot/server-unmanaged-extensions.html Cheers Michael Am 10.08.2011 um 14:16 schrieb Igor Dovgiy: > 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 server mode, and you can happily bombard it > with many queries from many clients' instances via standard REST API, > expanded with your plugin. > > And yes, we're using this kind of architecture, and kinda like it. ) > > -- > -- iD > > On 10 August 2011 13:10, sometime <dons...@gmail.com> wrote: > >> I wrote this plugin.
