        • Secure and robust compared to CGI scripts.
      • c) Servlet vs CGI
        • Difference in execution model – process vs thread-based.
        • Performance comparison (CGI creates a new process per request; Servlet uses threads).
        • Ease of maintenance and scalability.
        • Resource utilization and speed differences.
      • d) Setting up Apache Tomcat server
        • Downloading and installing Apache Tomcat.
        • Configuring Tomcat environment variables (JAVA_HOME, CATALINA_HOME).
        • Deploying servlet projects on Tomcat server.
        • Testing setup using a sample “Hello World” servlet.
    • 2. Servlet Life Cycle
      • a) init(), service(), and destroy() methods
        • init(): Called once when the servlet is first loaded; used for initialization.
        • service(): Called for each request; processes input and generates output.
        • destroy(): Called when servlet is being unloaded; used for cleanup.
      • b) Life Cycle Flow
        • Servlet loading by container.
        • Instantiation and initialization (init() method).
        • Request handling (service() → doGet() / doPost()).
        • Servlet destruction (destroy() method).
        • Diagrammatic explanation of Servlet Life Cycle.
      • c) Example: Basic HelloWorld Servlet
        • Creating a simple Java servlet class extending HttpServlet.
        • Implementing doGet() method to display “Hello World”.
        • Steps to compile, deploy, and access the servlet via web browser.
        • Understanding web.xml configuration (deployment descriptor).
    • 3. Handling HTTP Requests and Responses
      • a) HttpServletRequest and HttpServletResponse
        • Understanding the role of HttpServletRequest and HttpServletResponse objects.
        • Retrieving client data using request methods.
        • Setting and sending response content to the browser.
      • b) Request Methods: GET vs POST
        • Difference between GET and POST methods.
        • When to use GET (safe operations) and POST (data submission).
        • How browsers handle GET and POST requests.
      • c) Using doGet() and doPost()
        • Implementing doGet() for handling GET requests.
        • Implementing doPost() for handling POST requests.
        • Redirecting from doGet() to doPost() (and vice versa) when needed.
      • d) Reading Form Data from HTML
        • Creating an HTML form and connecting it with a servlet.
        • Using request.getParameter() to read input values.
        • Handling multiple form fields and radio buttons.
        • Example: User registration form handling with servlet.
      • e) Sending Responses to Clients
        • Using PrintWriter to send text or HTML output.
        • Setting content type (text/html, application/json, etc.).
        • Sending response headers and status codes.
        • Example: Returning dynamic HTML page as servlet output.
