Re: [Neo4j] Neo4J Plugin
Thank you andreas, So would the plugin will let me return Iterable where neoNodeResult is a custom class that have the following properties: 1. nodeType 2. nodeID 3. nodeStxCode 4. nodeLabel 5. nodeDepth I could return Iterable but its not what i want plus I need extra infos about the node to be returned.

Re: [Neo4j] Neo4J Plugin
Hi Francois, There is not direct support for doing that with a ServerPlugin. It is possible to write a custom Representation implementation that would help, but we haven't documented that approach. An alternative at the moment would be to write an unmanaged extension: http://docs.neo4j.org/chunked/snapshot/server-unmanaged-extensions.html The downside is that is rest-api specific. While the ServerPlugin Representation will work across any transport which we add to the server (currently only REST, but other wire protocols would be possible).

The downside is that is rest-api specific. While the ServerPlugin Representation will work across any transport which we add to the server (currently only REST, but other wire protocols would be possible). I'm not convinced of the validity or usefulness of this notion. A RESTful approach isn't simply a wire binding - it implies much more including the use of hypermedia (which our managed plugins use). If we're to build alternative wire protocols (e.g. a terse RPC protocol) then it wouldn't likely be RESTful, and I don't necessarily think it'd support server plugins as they are today.

[Neo4j] shortestPath exception
Hi all,
Pretty new to neo4j and am playing around with it to store some ontology data.
So far my experience has been pretty good but I am running into an odd issue
when trying to get the shortest path between two nodes using the REST API. The
command I am using is the following:
curl -H Accept:application/json -H Content-Type:application/json -X POST
http://localhost:7474/db/data/node/7212/paths -d
'{to:http://localhost:7474/db/data/node/2499,relationships: {type:
is_a, direction: in}, algorithm: shortestPath, max depth: 5}'
Which fails and prints out the following exception:

Re: [Neo4j] shortestPath exception
Hi,
this seems to be a bug. Which version are you running? Also I'd love
to get access to your data set so that I could trigger it locally and
fix the bug... Would that be possible?
Best,
Mattias
P.S. If sending the data then please mail me directly because
attachments won't get through the list. D.S

[Neo4j] Using Data tab of Web-Admin to Delete Relationships
I'm using the the Data tab of the Web-Admin (V1.3.M03) to model my data structure and learn Neo4j. I accidentally created a wrong relationship. I've selected that relationship (from both the parent side and child side/direction), and tried to remove it. No error appears, but it doesn't seem to remove it. (I press the back key and refresh, and it's still there.) Is there something I'm missing?
