Tomcat 6 + Jruby

I’m trying to configure a server with Tomcat 6 and mod_jk to serve up
ruby on rails apps built with netbeans 6.1. Does anyone know if there
are any issues? Sorry if this is a basic question, but I am very new to
ruby on rails and jruby. I think part of the issues might be that we
are trying to deploy these on a Tomcat 6 server when some parts might
require Glassifsh?
