"rescue in const_missing" error with Ruby 1.9.1, Rails 2.3.2, and jrails 0.4

Question

I recently started a project where the team decided we'd like to use jQuery rather than Prototype/Scriptaculous for our javascript needs. We set our project up, and began the switch. The plugin was installed via these instructions, and all went according to plan. Shortly after, when trying to run "./script/server", we get the following error:

I've done exensive searching, and can't find the reason for this error, or any documentation regarding version compatibility issues. Any help you guys can give will be greatly appreciated.

Thanks,

Answer 1

Looks like it's been patched to work with Ruby 1.9, try grabbed it from this git repo instead of the main site: http://github.com/cheald/jrails/tree/master

@Mike : Other plugin. Same problem. No solution. Hmm..
