Re: [jruby-user] Error 'uninitialized constant Arel::Visitors::SQLite' with rails

So you're mixing rails 2.3.8 (more than 4 years old) with the latest
release of a jdbcsqlite3 adaptor (few days old only) and you hope to
succeed? On top of this, you're using an almost 2 years old version of
jruby...

If you wish to succeed, and I guess some legacy is involved here (old
rails), please use at least a version of the jdbcsqlite3 adaptor that may
have been tested back then on jruby in 2010.

I would suggest using
https://rubygems.org/gems/activerecord-jdbcsqlite3-adapter/versions/1.0.3-java
and maybe also downgrade to jruby 1.6.8.

Good luck!
