A servlet is a Java programming language class used to extend the capabilities of servers that host applications accessed By means of a request-response programming model. Although Servlets can respond to any type of request, they is commonly used to extend the applications hosted by Web Serv ERs. For such applications, Java servlet technology defines http-specific servlet classes.

The javax.servlet and javax.servlet.http packages provide interfaces and classes for writing Servlets. All Servlets must implement Servlet the interface, which defines lifecycle methods.
