Re: [Neo] Re: Neo shell problems...
Hi, now I'm back (the brain behind the neo shell :) ). For starters, the Not in transaction bug was only found in the 1.0-b6 release. It's fixed though, only the shell download link doesn't refer to the latest jar file! Could someone please fix that! (I'll attach the right shell-1.0-b6.jar as well). There's also no assumption of an empty (or non-empty) database so you don't have to do that reference node thingies. As for the shell being started without a neo instance already started (just passing in the path to the neo store), that functionality got there in the neo/shell -1.0-rc1 version. Hopefully this new jar will fix the problems. / Mattias 2008/4/28 Emil Eifrem [EMAIL PROTECTED]: On Sun, Apr 27, 2008 at 11:54 PM, Philip Jägenstedt [EMAIL PROTECTED] wrote: I don't know why.

Re: [Neo] Maturity of Python bindings?
It could be a problem in maven because wou have to specify the java
source code version (i.e 1.6 or whatever you use). Maven has a
tendency to default to java 1.4. So here is what you'll want to
include in your pom.xml:
build
plugins
plugin
groupIdorg.apache.maven.plugins/groupId
artifactIdmaven-compiler-plugin/artifactId
configuration
source1.5/source
target1.5/target
/configuration
/plugin
/plugins
/build
So in a simple example the entire pom.xml would look like:
project
modelVersion4.0.0/modelVersion
groupIdmy-groupId/groupId
artifactIdmy-artifactId/artifactId
name/name
version0.1/version
build
plugins
plugin
groupIdorg.apache.maven.plugins/groupId

Very true, you can't run two Neo instances (processes, JVMs, etc)
against the same data store.
Also, I'm feeling slightly retarded this morning as I can't figure out
a good place to put my RelationshipTypes enum in Java. Essentially it
needs to be package global, so all I can think of is creating a silly
little class like this:
public class Mush {
public static enum Types implements RelationshipType {
MUSICBRAINZ,
ARTISTS,
ARTIST
}
}
You probably want to put it into a file RelTypes.java, which looks like:
enum RelTypes implements RelationshipType
{
BLAH, BLAH 2
}
Good luck!

Re: Compiling with Java 1.5 pom.xml (Was: [Neo] Maturity of Python bindings?)
Sorry for the late reply on your previous mail, this is what I answered exactely :) 2008/4/28 Philip Jägenstedt [EMAIL PROTECTED]: On 4/28/08, Emil Eifrem [EMAIL PROTECTED] wrote: You probably want to put it into a file RelTypes.java, which looks like: That was my first attempt, the class-wrapping was an attempt to get maven to compile.

Re: [Neo] Re: Neo shell problems...
Oh btw, sorry I meant that that it's the neo jar file which isn't the latest. You can download it here: http://m2.neo4j.org/org/neo4j/neo/1.0-b6/neo-1.0-b6.jar You could probably download the latest shell as well :) : http://m2.neo4j.org/org/neo4j/shell/1.0-b6/shell-1.0-b6.jar 2008/4/30 Philip Jägenstedt [EMAIL PROTECTED]: Looks like the mailing list doesn't like attachments.

Hmm, 1.0-rc1-SNAPSHOT? Is this the development branch, and is it
what I should use?
