Integrating Crystal Reports with Ruby on Rails

Hello:

I am looking to integrate Crystal Reports into my ROR application. I have been following this weblog for guidance - http://kkarthik.wordpress.com/ - but cannot seem to find any more resources for this on the web. Does this seem like the best method for doing so, and if not, what would be? Also, I am unable to locate all of the required JAR files for this process. Are these included in the download of either Crystal Reports 2008 or Crystal Reports Server 2008? I have these downloaded and still cannot locate the files. Thank you in advance for the support!
