Almost never. 99.9% of the time it's not what you want to do.

When:
When you wants some common processing for all request, like session check, any other message, etc..

How:
By extending org.apache.struts.action.ActionServlet. Make sure that you put the reference of this customized action servlet into DD.

That kind of behavior should go into a custom request processor, almost all the time.

Yes, that's more correct. ActionSerlvet delegates the request processing logic to RequestProcessor. So there is nothing you "really" need to extend it ;)
