Spring + JRuby on Rails

I've only been threatening to do this for a year, but I finally added the necessary stuff to have JRuby on Rails talking to Spring. There's a lot more to come here, but this controller code demonstrates being able to get ahold of a Spring WebApplicationContext in a Ruby on Rails controller.

class TestservletController < ApplicationController
  include Java
  import javax.servlet.ServletContext
  import org.springframework.web.context.WebApplicationContext
  import org.springframework.web.context.support.WebApplicationContextUtils
  
  def showcontext
    app_context = WebApplicationContextUtils.getWebApplicationContext($servlet_context)
    render_text app_context.display_name
  end
end

In order for this to work, you'll have to use the very latest goldspike-snapshot plugin from SVN trunk. I just checked in the code to expose $servlet_context earlier today. Obviously this code will only work using a servlet container, and you'll need to have Spring and necessary deps in WEB-INF/lib and have the Spring context loader listener in your web.xml. From here, my next step is some metaprogramming to allow you to add spring bean accessors into your controllers.
