Problems with classpath using BIRT
Johann Schweigl
scripted data source) in Eclipse Report Designer, but I'm failing at
the basics:
Script engine error: Wrapped java.lang.IllegalArgumentException: No
index provider 'lucene' found. Maybe the intended provider (or one
more of its dependencies) aren't on the classpath or it failed to
load.
I put all of the Neo jars (Community 1.6 M1) I'm using in the Java
project which creates the data in the BIRT classpath (Window/
Preferences/Report Design/Classpath), so the lucene index provider
should be there. Some googling brought me to the assumption that this
could have something to do with OSGi, but as I never ever touched this
OSGi beast, I'm pretty clueless on this.
Has anyone tried something similar with success?
BTW: The Java API only works against an embedded database, right? I'm
asking, because I also downloaded the Neo4j JDBC driver, which I'd
massively prefer over that scripted datasource mess in BIRT, but the
JDBC driver apparently works exclusively against a Neo server, not an
embedded database. Which means I'd have to scrap everything I did on
the Java API up to now, and this is not an option.

I think you are right, there might be OSGi issues involved. If you
build and try the superbundle from https://github.com/neo4j/neo4j-osgi
and try that, is that working?
Also, a very cool thought would be to build an embedded JDBC driver
variant that accesses Cypher results direcetly, not via REST JSON
parsing. Something for tinkering over XMas with? ;)

Not just the neo4j-lucene-index.jar
Michael

will then try and figure out what to do with it :-)

https://github.com/neo4j/neo4j-osgi ? I'm running git 1.7.8.msysgit.0
on Win2K8 Server R2. I have to confess that I avoided git at all cost
(and find myself confident that this was a Good Thing) up to now,
using just Eclipse & SVN, no maven, so experience is zilch.
I changed the "git co g...@github.com:neo4j/community.git" to "git
clone git://github.com/neo4j/community.git", otherwise nothing would
happen in the first place. Then I did a "git branch -t bundle-friendly-
classloader origin/bundle-friendly-classloader" which looked good.
"mvn clean install" ends up in

just to be sure I started out with a fresh git install, created a user
at github, forked the neo4j/community project, copied it to a local
repo and checked out the bundle-friendly-classloader branch. Did I say
that I'm learning a lot about git these days? Never hurts ;-)
However, this all went a bit different from the build instructions at
https://github.com/neo4j/neo4j-osgi:
git co g...@github.com:neo4j/community.git
cd community
instead I did
git clone g...@github.com:jschweigl/community.git (from my fork, which
I believe was unneccesary to do)
git remote add upstream git://github.com/neo4j/community.git
git fetch upstream
cd community
git checkout bundle-friendly-classloader
Still being a noob, I just followed what I believed to understand from
various sources, but it felt somehow right.
"mvn clean install" again failed in a test case:

that class is generated rom calling out to GIT on the command line.
Could we meet up in Skype to sort out if there is setup problems? Then
we can modify the assertion message to give more hints on potential
problems ...
