Deployment of non rails ruby apps to tomcat using warbler

Hi

I am a newbie to ruby. Tried using warbler to package a ruby app to be
deployed onto tomcat 6.0

Have checked out
http://kenai.com/projects/warbler/pages/Home
http://stufftohelpyouout.blogspot.com/2009/06/how-to-get-warbler-to-include-custom.html

Have error on tomcat
undefined method ‘exclusive’ for Thread:Class from
c:/tomcat/webapps/abc/WEB-INF/gems/gems/innate-2009.06.12/lib/innate/node.rb:216
etc…

Does this mean anything to anyone?

As web.xml in a tomcat goes… What should I see in web.xml created by
warbler when packaging… Should this be similar to config.ru

Thank you
