Rails - Aug 2006 - N00b question...but here it goes

Hey all,
How can I call a javascript function from my controller?
Is it possible to simply call a javascript function
from directly in the controller without needing an AJAX
request to come through via link_to_remote or remote form?

I''m not talking through an RJS link_to_remote AJAX etc.

As an example I''ve tried:

class RandomController < ApplicationController
  before_filter :login_required, :except => [:index, :initialize]
  def index
    @session[:mode] = ''view''
    @map = GMap.new("map")

    render :update do |page|
      page.call("resizeMap")
    end

    @map.control_init(:large_map => true, :map_type => true)
    @map.center_zoom_init([38.539506, -121.757172],13)
    store_location
  end
end

This as expected does not work, it spits of the try{blah blah} catch 
stuff.
Any help is greatly appreciated!

Russ
