Hello everyone May I chime in here...
We are really interested to see neo4j working in an OSGi environment esp. together with Spring Data Graph. After an unsuccessful attempt to get it up and running a couple of weeks ago we gave it another chance today after seeing this post and after a whole day of debugging and fiddling around with manifests and template.mf and osgi.bnd we have - hurray - a running neo4j and Spring Data Graph setup in Virgo (based on Equinox). Regarding the error with the missing lucene index Provider (java.lang.IllegalArgumentException: No index provider 'lucene' found) I also would like to refer to this "discussion" here: https://github.com/neo4j/community/commit/e8574e96315999ab04e1b484717bb2b1a3dfa9be#commitcomment-483325 I also had the "No index provider 'lucene' found" error with neo4j 1.4. With 1.3, the workaround was to export the org.neo4j.index.impl package, which is not working with 1.4. Instead I just registered an instance of LuceneIndexProvider from the lucene-index bundle as a osgi service. After doing this, this index provider can be found as an OSGi service by the kernel. We currently register this service within our application, which is probaby not the right solution. I think the lucene-index bundle should export the LuceneIndexProvider service itself, shouldn't it? I also tried to get your example up and running, but I have a missing dependency: "Failure to find org.ops4j.pax:tinybundles:jar:1.0.0-SNAPSHOT". Which snapshot repository does contain the tinybundles jar? Best regards, James 2011/7/20 Peter Neubauer <neubauer.pe...@gmail.com>: > Yup, > have pulled and can see it. Thanks!
