Aha! There you go… While you’re following this article you should forget you have Ruby installed in your machine. All the gems should be managed by the gem script provided by JRuby.

Try removing Ruby from your PATH and installing the gem again. Shout if you have any problems

Yes, I’ve set all files in the script directory to use jruby. I’ve got the same error again. Looks like the jdbc-adapter isn’t installed… But it is, at least in the C:\ruby (do i need to install it in the jruby directory too?). Netbeans IDE found it when i’ve checked in the gems configurations….

If you’re sure the activerecord-jdbc-adapter gem is installed correctly, try taking a look in the script files generated by rails. Are they pointing to Ruby or JRuby?

Oh, I forgot, my PATH it’s ok too. I can use jruby in my command window as well, so, I think, there isn’t any problem with the ’script‘ directory.

Hi.
Everything went fine ’till the test with the new database.yml (using the jdbc) configuration. My JRUBY_PATH its ok too (I’m under WINXP).
But, when I start de Webrick I get this annoying message:

“C:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/connection_adapters/abstract/connection_specification.rb:231:in `establish_connection’: Please install the jdbc adapter: `gem install activerecord-jdbc-adapter` (no such file to load — java) (RuntimeError)”

But I’ve already installed the jdbc adapter and copied the “mysql-connector-java-5.1.6-bin.jar” to JRUBY_HOME/lib

Any sugestion?

Thanks in advance!
