In your
servlet, try:
What you want is probably in the ActionMapping, if this isn't what you were looking for. Since the servlet can actually be mapped to many different Actions, the servlet itself won't know where it came from.
Why do you need to know the Action the servlet is being called from? Debugging? You probably shouldn't have specific functionality tied to which mapping your servlet is using. I would break these out into specific Action classes if you are.
