      • Core JSTL tags (c:if, c:forEach, c:set, etc.).
      • Formatting and localization with fmt tags.
      • Handling collections and arrays in JSTL.
  6. JDBC (Java Database Connectivity):

    • Topics:
      • Establishing database connections.
      • Executing SQL queries and updates.
      • Handling result sets and database errors.
      • Prepared statements and connection pooling.
  7. Session Management:
    • Objective: Manage user sessions to store and retrieve data.
    • Topics:
      • Understanding HTTP sessions.
      • HttpSession object and its methods.
      • Cookies and URL rewriting for session tracking.
  8. Error Handling and Exception Handling:
    • Objective: Handle errors and exceptions gracefully in web applications.
    • Topics:
      • Configuring error pages in web.xml.
      • Handling exceptions using try-catch blocks.
      • Custom error pages and error codes.
  9. WAR Files (Web Application Archive):
    • Objective: Package and deploy web applications in a standard format.
    • Topics:
      • Creating a WAR file structure.
      • Deployment descriptor (web.xml).
      • Deploying a WAR file to a servlet container like Tomcat.
  10. Servlet Filters:
    • Objective: Understand request and response filtering for various purposes.
    • Topics:
      • Filter interface and filter chains.
      • Implementing filters for authentication, logging, and data transformation.
      • Filter configuration in web.xml.
  11. Authentication and Security:
    • Objective: Secure your web application with user authentication and access control.
    • Topics:
      • Implementing basic authentication with servlets.
      • Role-based access control (user roles and permissions).
      • Best practices for secure coding.
  12. RESTful Web Services (Optional):
    • Objective: Explore RESTful services using Servlets for API development.
    • Topics:
      • Introduction to REST architecture.
      • Building RESTful APIs with Servlets.
      • Consuming RESTful services in Java web applications.
  13. MVC (Model-View-Controller) Architecture:
    • Objective: Learn the MVC pattern for structured web application development.
    • Topics:
      • MVC fundamentals: Model, View, Controller.
      • Separation of concerns in web applications.
      • Advantages of MVC.
  14. Deployment to Tomcat:
    • Objective: Understand the deployment process on a Tomcat server.
    • Topics:
      • Installing and configuring Apache Tomcat.
      • Deploying web applications to Tomcat.
      • Server configuration (e.g., server.xml and context.xml).
  15. Project Work:
    • Objective: Apply the learned concepts to a practical project.
    • Outcomes: Students should complete a web application project using Servlets and JSP, demonstrating their understanding of web development concepts.

Outcome: By covering these topics and objectives, students will gain a solid foundation in Java web application development using Servlets, JSP, JSTL, JDBC, WAR files, and Tomcat deployment, enabling them to build dynamic and secure web applications.
