RUBY on Rails Bible" Ch. 7 bookshelf example, Amazon AWS help

Im a newbie.   The last post here on the subject, posted on 2009-11-19 08:53:19,

and responses to it, may be out of date:  the code there does not work for me,

(it does not seem that my SECRET_KEY is getting through) .  Per the book, Im

using Ian Macdonald's Ruby/AWS interface.  Also, is it possible that it is

NECESSARY to get an "Associates_ID" in order for one's SECRET_KEY to work,

although this was not necessary before (I have not gotten one ). ?

  Essentially Im getting the dreaded HTTP 400 error.  From what I can make of

things, my AMAZON secret key is not getting through, from the line:
        resp =

  Im getting two kinds of errors.

error 1)  "
RuntimeError in BookController#search

ObjectSpace is disabled; each_object will only work with Class, pass -X+O to


Well, I did a little homework on this one, and then hesitantly enabled

ObjectSpace by adding these two lines to development.rb:

  require 'jruby'

now , i get error 2:  "
Amazon::AWS::HTTPError in BookController#search

HTTP response code 400

...with the "get_page"  and "search" lines being the top two in the trace

report, just as in the previous post mentioned above.

In both error cases, the error report lists an "authenticity_token" that does

not match my secret key (which I put in an Amazonrc.txt file per recent

instructions).  And from my testing using rails console, it does seem as though

I get the path to Amazonrc.rb handled appropriately.

anyway , heres my code and some relevant info. Tx in advance for your help !!

Windows XP
Netbeans 6.8 IDE
RUBY/AWS 0.8.1, installed via RubyGem
