I'm not aware of any huge-scale environments, that would be running on Jboss, Resin or Zope (or Websphere).
The open source ones are fairly untested in _huge_-scale environments AFAICT (then again, so was PHP until recently). But for "enterprise level" scalability, see http://www.zope.com/customers/case_studies.html http://www.jboss.com/customers/index
eBay is "powered by WebSphere" and probably a good comparison as a dynamic web application. They're still getting more traffic than we do. ;-)
I'm not totally compatible with all enterprise software, but at least Amazon is using pretty lightweight setup with most of stuff being routed to 'services' around, SOAP, WSDL, yadda yadda. I'm not sure if they need full-blown app server for this at the front.
What I do know is that they're making a bloody mess out of all those aggregated web services. A little tagging here, a little wiki there, here's some recommendations, and a wishlist and a puppy, too ...
