Hi
When I run my Rails application using Tomcat/Trinidad I get "No index
provider 'lucene' found", see stack trace below
I think I have seen a similar problem on the gremlin email list.
I guess it's because of a class loading issue, or maybe the
META-INF/services files,
or because in JRuby the neo4j jar files are loaded at runtime.
I need some hints where I should start looking.
I have tried to manually add the neo4j-lucene-index-1.3.M02.jar file
to the classpath without any luck (jruby -J-cp /home/... -S trinidad)
The problem occurs in neo4j.rb version >= 1.0.0.beta.17 when the new
lucene index framework was introduced.
It works in WEBrick/rails s
