Hi Please go through the topic below:
Mapping URLs to Web Components: When a Web Component receives a request, the web container must determine which web component should handle the request. The web container does so by mapping the URL path contained in the request to a web application and a web component. A URL path contains the context root and, optionally, a URL pattern: http://host:port/context-root[/url-pattern] You set the URL pattern for a servlet by using the @WebServlet annotation in the servlet source file. For example, the GreetingServlet.java(name assumed,make ur own ) file in the hello2 application contains the following annotation, specifying the URL pattern as /greeting: @WebServlet("/greeting") public class GreetingServlet extends HttpServlet { ... This annotation indicates that the URL pattern /greeting follows the context root. Therefore,when the servlet is deployed locally, it is accessed with the following URL: http://localhost:8080/hello2/greeting To access the servlet by using only the context root, specify "/" as the URL pattern.
