Topic: Problems using Periodically_call_remote

I'm looking for help/advice on using 'periodically_call_remote', in order to perform a simple regular refresh of a page. AFAIK it is not user in Rails 3 but the system I am using is Ruby 1.9.1 and Rails 2.3.3.  I can't seem to find any documentation about it, as all docs now point towards Rails 3.  From the examples I've found I thought it wold simply be a matter of putting ...
<%= periodically_call_remote(:url => { })

When that didn't work I expanded it to ...

<%=javascript_include_tag 'application'%>
<%=javascript_include_tag 'prototype'%>
<%= periodically_call_remote(:url => { :action => 'new' }, :frequency => 20) %>

But still no joy.  Can anyone please offer some advice/help?  Thanks in advance.

Re: Problems using Periodically_call_remote

So, I searched a little harder (yes, I know, probably should have done so before posting) and from other posts in this forum I determined that one also needs ":update" in the call, and that this would normally point to the name of a 'div' on the page, and that that div should have its own method in the parent controller.  Also, if using a partial, a respond to statement is needed in that method, otherwise the file it looks for is one without a leading underscore.

def my_partial_method
  @stuff = ####
   respond_to do |format|
     format.html do
         render :partial => "/my_controller/my_partial_method"
