I would like to make a Struts2 action class not return anything. I would like it to act like a receiver of requests, for example notifications, and then just end. Unfortunately the action class's execute method returns a String. Any thoughts?
It seems like you don't want your application server to send a response. I'm not sure if there is an easy way to get it to do that. Maybe there is something you can do to the httpresponse to get it to not return. Sorry, I don't have any more specific advice.
static final String NONE The action execution was successful but do not show a view. This is useful for actions that are handling the view in another fashion like redirect.
