Shane,
I think it's probably going to be a lot easier to take an approach like I
did and use a metaprogramming approach to add your Spring beans into your
controllers than it is going to be to have Spring inject into your Rails
code This is the approach I'm planning for my Spring Rails plugin to take.
Check out my blog post for details and example code:

I'm putting together a proof of concept application where I'd like to
elegantly inject Spring beans on Rails controllers. I successfully got
an instance of the Spring applicationContext using
WebApplicationContextUtils and the servlet_context introduced by Chris
Nelson. I'm now defining the Rails controller in the Spring context
and trying to inject a Java bean into it.
Here's what I have so far:
----> in applicationContext.xml:
<lang:jruby id="booksController"
script-interfaces="
com.digitalsanctum.jrubyprototype.jruby.BookStoreAware"
script-source="/app/controllers/books_controller.rb">
<lang:property name="bookStore" ref="bookStore"/>
</lang:jruby>
----> in books_controller.rb:
require 'java'
#include_class '
org.springframework.web.context.support.WebApplicationContextUtils'
include_class 'com.digitalsanctum.jrubyprototype.domain.logic.BookStore'
class BooksController < ApplicationController
def setBookStore(bookStore)
@@bookStore = bookStore
end
def list
# @book_pages, @books = paginate :books, :per_page => 10
logger.info("reached list")
# ctx = WebApplicationContextUtils.getWebApplicationContext
($servlet_context);
# bookStore = ctx.getBean("bookStore");
logger.info(@@bookStore)
end
...
end
----> Here's the exception:

I realize this is a Spring exception but I'm guessing this list would
have a better idea of what's going on rather than a Spring mailing
list. Looking at the exception, it seems like Spring isn't aware of
the Rails superclass ApplicationController but I'm not sure of the
best way to handle this.
Any guidance is appreciated.
