upgrading from jetty_rails 0.6 into 0.8 broke javascript_include_tag

I believe it's a jruby_rack issue. You can work around it by changing the public.root variable in web.xml to /public/../ Strange hack, but it works for me.

<context-param>
  <param-name>public.root</param-name>
  <param-value>/public/../</param-value>
</context-param>

I have the same problem, realy looks like a jruby_rack bug:

If I run a jruby (standalone) script that creates a jetty server using rack, I'm getting the same problem.

to fix this edit: jetty-rails0.8.1/lib/jetty_rails/handler/web_app_handler.rb
on line 11 change
