And he explicitly gets this message: "warning: ActiveRecord-JDBC is for use with JRuby only" So that's the problem - following someone's instructions for JRuby when you're not running JRuby :-) I'm afraid I don't use Windows. Under Linux the gems I need are: activerecord activerecord-oracle-adapter and I also need ruby-oci8 installed - which I build from source, and which needs the Oracle client libraries around (I have oracle-instantclient-devel, oracle-instantclient-basiclite, oracle-instantclient-sqlplus) If you go to the ruby-oci8 homepage I expect you'll find either a ready-made Windows package, or instructions for installing it under Windows.
