Re: [Neo4j] Cannot build neo4j-cypher-plugin

2011-06-12 Thread Super Wang 
My mistake, it's neo4j-cypher-plugin, not neo4j-cypher.

But my neo4j-cypher project reports errors in eclipse IDE, it looks like it
requires some scala classes in java classes, and eclipse cannot handle this.

org.neo4j.server.webadmin.console.CypherSession
org.neo4j.shell.kernel.apps.Start

have compiler errors too, both of these are require scala classes...

By looking at the code in org.neo4j.cypher.javacompat.CypherParser which
report compiler error:

package org.neo4j.cypher.javacompat;

import org.neo4j.cypher.SyntaxError;
import org.neo4j.cypher.commands.Query;

both two imports are missing, the package org.neo4j.cypher itself is empty.

[Neo4j] Traversals versus Indexing

What is faster - Traversals or Indexing? I mean if one has a database model
that can offer a choice between the two, what should one choose?
Also, what about when the scalability factor comes in?

Re: [Neo4j] No index provider 'lucene' found

2011-06-12 Thread Ian Bussières 
I was wondering if anybody had a workaround or fix to my issue.
Otherwise, is there a new or other way to accomplish indexing, as that
portion of work would take me very little time to recode.

Thanks !

Re: [Neo4j] Cannot execute Cypher

2011-06-12 Thread Peter Neubauer 
Mmh,
that is strange. Btw, the cypher console is running against the
build-in console service, and the cypher-plugin is only for the REST
representation.

What browser are you running?

[Neo4j] Cannot find a path

2011-06-12 Thread Josh Adell 
Hello all,

I recently began exploring Neo4j REST interface, and I am having a problem
finding paths between nodes.
I am using neo4j-community-1.4.M03

My nodes and relationships look like this (verified using the webadmin
interface):

(1: Node A) IN> (3: Node C)

Re: [Neo4j] REST results pagination

2011-06-12 Thread James Thornton 
Gremlin makes sorting results easy...

g.v(1).out.sort{it.lang}.reverse().toList()

For more details, see this thread in the Gremlin Users group

Re: [Neo4j] traversing backwards to reference node

2011-06-12 Thread Marko Rodriguez 
Hi,

In Gremlin (http://gremlin.tinkerpop.com), you can do:

startSet = [ ... ] // fill an array/set with leaves.
startSet.in.sideEffect{it.myProperty = 'blah'}.loop(2){true}

In this code, it assumes no cycles in the graph and that the root of the tree 
as no incoming edges. 

---

If you are using Gremlin 1.1-SNAPSHOT (all pumped up on it), you can do:

startSet.as('x').in.sideEffect{it.myProperty='blah'}.loop('x'){true}

Finally: if you have lots and lots of data, then you will want to not have 
AUTOMATIC transactions and will want to put the graph into MANUAL transaction 
mode before you start the traversal. I can say more if you are interested.

See ya,
Marko.

Re: [Neo4j] traversing backwards to reference node

2011-06-12 Thread Rick Bullotta 
BTW, we use a similar technique in our domain model to dynamically build a URI 
for any entity in our system, which corresponds to the REST API URI for that 
entity.  As an example:

A blog entry "XXX" is an entry (relationship = BlogEntry) in a blog named "YYY" 
which is in the collection of things named "Blogs" (relationship = Blog) which 
in an application named "ThingWorx" (relationship = Blogs).  By walking this 
hierarchy, similar to walking a filesystem, we can generate a URI such as:  
/Thingworx/Blogs/YYY/BlogEntry/XXX.

Hey all, I'm new to Neo4j and I'm really liking it.  I'm not sure if its the
right tool for my particular job though.  I'd like to model a rather larse
filesystem (multi-petabyte) and use it to overlay additional metadata or
info.  The nice thing about neo4j is that if someone moves deeply nested
data, all I have to do is update a relationship to point somewhere else.

I'm wondering if anyone can show me a traversal method that will walk
backwards to the reference node, adding a "name" property to a list as it
goes.

Re: [Neo4j] traversing backwards to reference node

2011-06-12 Thread Rick Bullotta 
There is no "generic" way to do this that would provide the semantically 
correct traversal for you, but depending on how you've modeled your 
relationships and nodes, it should be fairly easy to do.  The trickier part 
will be dealing with backwards traversals if you allow "file" nodes to be 
multiply linked to more than one parent directory.  If that's not the case, you 
should be able to just to a traversal on the directory -> file relationship, 
and add the "name"(s) to a HashSet or ArrayList as you do.  The other question 
is whether you might need to create unique or full qualified file names as you 
do (e.g. include the full path name?).

Re: [Neo4j] Error(s) found in manifest configuration when trying to import community/pom.xml

2011-06-12 Thread Chris Gioran 
Hi there,

the problem is the maven version you are using - Neo4j does not work
well with mvn 3. The exact same steps are successful with my setup
which is the same but for maven 2.2.1
I suggest you downgrade your maven install or create an environment
for Neo4j that uses mvn 2, until we become maven 3 compatible.

cheers,
CG
