we will define the action servlet in web.xml and <url-pattern> as *.do
for mapping the requests which ends with .do , but we dont write the doget and dopost methods as we write in normal servlets.
Main function of action servlet is to process the request and forward it to appropriate action class (*.do). Source: CoolInterview.com

What is the difference between a normal servlet and action servlet?

Ans:- The ActionServlet is a predefined servlet type class which comes along with struts framework, It follows the ?Front Controller? design pattern. Then main purpose of the ActionServlet is to receive the every request from the client and control the flow of process by using some helper classes like RequestProcessor. The programmer can directly use this class with out any implementation of it because it's already defined.


Normal Servlet: In case of normal servlet we should extends our class either from GenericServlet or HttpServlet or else implements Servlet. The Normal servlet doesn't follow the ?Front Controller? design pattern that means every servlet might not be comes to the same servlet. Every request might point to different servlet.
