Re: [Neo4j] How to build neo4j projects from GitHub
I'm building the community project which I can successfully done through command line, mvn clean install. The problem is only when importing to eclipse. something class files are missing. they are all in Cypher project like org.neo4j.cypher.SyntaxException, org.neo4j.cypher.commands.Query. in the Cypher project, there are only org.neo4j.cypher.javacompat package. does the pom link to a wrong cypher project?

Re: [Neo4j] How to build neo4j projects from GitHub
Hi! AFAIK, this is an Eclipse Indigo annoyance. Does sound a bit strange, as we already told Eclipse/m2e how to handle that execution by the configuration over here: https://github.com/neo4j/parent-central/blob/master/pom.xml#L357 Maybe you just need to do (project) -> Maven -> Update Project Configuration? Sometimes that is needed after an import in order to get Eclipse properly configured. /anders 2011-10-15 13:09, Brendan cheng skrev: > > I was using the import from eclipse GUI so...no log message but a screen shot > which I attached. > >> Date: Sat, 15 Oct 2011 12:41:28 +0200 >> From: peter.neuba...@neotechnology.com >> To: user@lists.neo4j.org >> Subject: Re: [Neo4j] How to build neo4j projects from GitHub >> >> That sounds ok.

Re: [Neo4j] Lucene index recovery
What if in production due to whatever reason the neo4j server died and in the case people have to start up a new server with the current snapshot of data (which would be data from a non-clean shut down). In such case, I don't think it's acceptable to table lots of time (hours for large indices) to bring the server back. Is there a best practice here?

[Neo4j] WebAdmin visualization (are rels. labels configurable?)
Hi! I just tried the WebAdmin visualization time for the first time and it seems pretty cool. I have one question though, can be relationships labels be different than the rel. name? I've been playing a bit with the display options for nodes but didn't find anything for relationhips.

Re: [Neo4j] Index Creation via REST API
This looks right. Can you create the error with a curl call so I can
recreate it?

[Neo4j] Index Creation via REST API
Hello,
trying to work RESTfully with Neo4j via Standalone Server (1.5.M01) I'm
about to become desperate.
I'm sending an POST-Request to
http://localhost:7474/db/data/index/node/, getting status-code 500 with
the response-text "java.lang.Boolean cannot be cast to
java.lang.String".
The indexes I've wanted to create are the following one:
{"name":"address","config":{"provider":"lucene","type":"fulltext"}}
{"name":"user","config":{"provider":"lucene","type":"fulltext"}}
Neo4j log contains the following line:
"17.10.2011 16:56:10 org.mortbay.log.Slf4jLog warn
FATAL: /db/data/index/node/
java.lang.ClassCastException: java.lang.Boolean cannot be cast to

[Neo4j] Python embedded and Java batch inserter
Hi all, I'm trying to work with Neo4j embedded with Python, but, if I try to open a database created with the Java batch inserter (neo4j 1.4) by using Python-embedded, I get the error described here https://trac.neo4j.org/ticket/275 The database works correctly when opened in Neoclipse or with neo4j stand-alone server (by replacing the data folder), and if I create a new database directly with Python embedded it works too. Is there a way to solve this problem? Then, how much is fast the neo4j-REST traverser compared with the Java embedded traverser on a 3 million nodes graph? Cheers!

Re: [Neo4j] Configuring Neo4J via Python bindings
Hey Chris, I've just added support for passing in extra JVM args, it's available as of this commit: https://github.com/neo4j/python-embedded/commit/d41950f8c7e6c65d67f60868976e1864a496a2ea Documentation will pop up in an hour or so here: http://docs.neo4j.org/chunked/snapshot/python-embedded-reference-core.html This feature will be available as of the 1.5 release, due later this week. If you want to get access to it right away, you can build neo4j-embedded directly from source, the code is available here: https://github.com/neo4j/python-embedded See the readme for how to build from source.

Re: [Neo4j] WebAdmin visualization tool for large DB ?
I think that both Neo4J and webadmin should have the option of specifying "first N" relationships as a "limiter". This limit should be on a per-relationship basis (e.g. the first "N" of each type, rather than simply the first "N" relationships). This way, you would be able to visualize all of the relationship types that go in/out of the node, but not be overwhelmed with one specific relationship type. Also, it would be ideal if some visual cue that there were more relationships of a given type could be provided (e.g. a relationship line to a box labeled "...and 10,679 more" From: user-boun...@lists.neo4j.org [user-boun...@lists.neo4j.org] On Behalf Of Pablo Pareja [ppar...@era7.com] Sent: Monday, October 17, 2011 6:44 AM To: Neo4j user discussions Subject: Re: [Neo4j] WebAdmin visualization tool for large DB ?
