In the next screen, choose the auto-generated method stubs. For simple servlets like ours doGet and doPost would suffice. Click on the Finish button to complete the process.

Give some implementation in the method stubs. I’m gonna just say hello world and tell visitor to visit my website for QA articles as shown :

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub response.getWriter().append("Served at: ").append(request.getContextPath()); { response.setContentType("text/html"); PrintWriter out = response.getWriter(); out.println("<html>"); out.println("<head>"); out.println("<title>Hello World!</title>"); out.println("</head>"); out.println("<body>"); out.println("<h1>Hello World!</h1>"); out.println("Visit for interesting QA stuff..!!"); out.println("</body>"); out.println("</html>"); } }


Save the changes and deploy the application in the Tomcat server as shown in the above link.

Note that trying to visit the URL before deploying the servlet, would display 404 not found error.


goGet method stub

Run the Servlet

Visit the servlet URL or run the servlet on the server :
