Both a normal servlet and action sevlet are same, which extend HttpServlet and implement the servlet lifecycle methods..

Action servlets in Struts do specifically the following three actions: 1. Invokes  Do Post()/Get Post() 2. Selects proper sub application 3. Invokes process() on Request Processor.

There will be one action servlet per each application module.

General servlets can contain any processing logic.

Hi Folks,

Ordinary Servlets:

These are extends HttpServlet, and service the req, and send the response to the client. At the time, servicing, the container will create the objects for this servlets, when ever, it needs.

ActionServlet:

This also extends HttpServlet. But it wont create objects more than one, instead, it will service the request, by using single object. This is called, SingletonPattern. So, ActionServlets are designed by singleton pattern.

Thanks for recalling.
