Have problems building neo4j GetAll server extension - neo4j

Question

I have been trying to build the example GetAll neo4j server extension, but unfortunately I cannot make it work. I installed the Windows version of neo4j and run it as a server. I also installed Python neo4jrestclient and I am accessing neo4j through Python scripts. The following works fine:
from neo4jrestclient.client import GraphDatabase
gdb = GraphDatabase("http://localhost:7474/db/data/")
print gdb.extensions
It gives me "CypherPlugin" and "GremlinPlugin". I want to build the example GetAll server extension, which is Java. I am using Eclipse. I am able to create the jar file in the folder "c:\neo4j_installation_root\neo4j-community-1.7\plugins\GetAll.jar", but when I restart the neo4j server and run the neo4jrestclient it does not show the GetAll server extension. I searched a lot, but in vain. I have lots of experience with C++ and Python, but new to Java. I will really appreciate some help to be able to build neo4j server extensions. It is critically important for my evaluation of neo4j.

Answer 1

Are you sure there is a META-INF/services etc listing the plugin class, and the jar file is created with intermediate dirs (which is not the default in Eclipse export settings) so dirs are seen by the classloader?

You can do get-all with Bulbs (http://bulbflow.com) without building an extension:
>>> from bulbs.neo4jserver import Graph
>>> g = Graph()
>>> g.vertices.get_all()
>>> g.edges.get_all()
Custom models work the same way:
# people.py
from bulbs.model import Node, Relationship
from bulbs.property import String, Integer, DateTime
from bulbs.utils import current_datetime
class Person(Node):
element_type = "person"
name = String(nullable=False)
age = Integer()
class Knows(Relationship):
label = "knows"
created = DateTime(default=current_datetime, nullable=False)
And then call get_all on the model proxies:
>>> from people import Person, Knows
>>> from bulbs.neo4jserver import Graph
>>> g = Graph()
>>> g.add_proxy("people", Person)
>>> g.add_proxy("knows", Knows)
>>> james = g.people.create(name="James")
>>> julie = g.people.create(name="Julie")
>>> g.knows.create(james, julie)
>>> g.people.get_all()
>>> g.knows.get_all()
