[Neo4j] GremlinPlugin in REST
Hi, all,
Today I have downloaded the last version of Neo4j, thus, 1.5.M01. I
run some of my tests and some of them falied, what related to Gremlin
plugin.
If I run using Neo4j 1.4.1 I get the next:
$ curl http://localhost:7474/db/data/ext/GremlinPlugin/graphdb/execute_script;
{
extends : graphdb,
description : execute a Gremlin script with 'g' set to the
Neo4jGraph and 'results' containing the results. Only results of one
object type is supported.,
name : execute_script,
parameters : [ {
description : The Gremlin script,
optional : false,
name : script,
type : string
}, {
description : JSON Map of additional parameters for script variables,
optional : true,
name : params,
type : string
} ]
}
But when I use the Neo4j 1.5.M01:
$ curl http://localhost:7474/db/data/ext/GremlinPlugin/graphdb/execute_script;
html
head
meta http-equiv=Content-Type content=text/html; charset=ISO-8859-1/

Is that normal? is there something that I'm doing wrong?
Thanks.

Re: [Neo4j] GremlinPlugin in REST
Wohow,
this is actually a bug introduced when we added Maps as parameter
types. I added a test for it in the gremlin-plugin, and fixed it in
server,
https://github.com/neo4j/community/commit/ed42542e191de9966e1b5ada80bf8a6684bd6d1d
As snapshots get out, you should be able to run it normally in Neo4j
Server 1.5-SNAPSHOT.
Thanks for reporting it - it surfaces only when you do a GET on the
Gremlin plugin URL!
Cheers,

Thank you for the very quick response and fix. I'll try the new snapshot.
