Typically you use DWR to integrate with your business layer (Managers)
and not the web controllers. It looks like DWR can't call your action
because the action is called outside of the Struts context.
DWR is more about marshalling direct from your business layer to
client JavaScript, hence the name. So if you can't call your business
class or don't have one, then perhaps you really want to make an AJAX
http request to struts instead. I have had success with Jquery
calling Struts actions that output JSON results using the JSON plugin.
