This module explores the use of servlet configuration and context objects, enabling learners to manage shared application data and initialization parameters. The lessons focus on differentiating between ServletConfig and ServletContext, understanding their practical use cases, and configuring servlet behavior through load-on-startup mechanisms. This sets the stage for building efficient, state-aware web applications.

This module introduces the Model-View-Controller (MVC) architectural pattern within the context of Java Servlets. Learners will explore how to separate concerns in web application development, implement request dispatching using RequestDispatcher, and understand how forwarding and redirection operate within servlet-based architectures. Through practical code examples and guided explanation, this module emphasizes clean design and control flow in servlet applications.

This module focuses on preserving user data across multiple interactions with a web application. Learners will explore the core techniques of session tracking in Java Servlets, including cookies, hidden fields, and URL rewriting. The lessons provide hands-on exposure to maintaining state in stateless HTTP environments, helping learners build more interactive and user-aware applications.

This module extends session tracking by focusing on HTTP session objects and cookie-based authentication mechanisms. Learners will learn how to implement login/logout functionality using both session and cookie strategies. By building end-to-end examples, this module helps consolidate skills in user session control, secure access, and lifecycle handling of web interactions.

This module introduces learners to database fundamentals and SQL operations in the context of Java web development. It begins with a foundational overview of relational databases and continues through practical SQL syntax, covering commands for data manipulation, definition, and constraint enforcement. Learners will understand how to prepare data environments for backend integration with servlet-based applications.

This module bridges Java web applications with backend databases using JDBC (Java Database Connectivity). Learners will explore how to establish connections, perform CRUD operations, and securely interact with database systems through servlets. The lessons emphasize JDBC classes and interfaces, as well as best practices for real-world data handling.

This final module focuses on enhancing servlet applications through the use of filters and user authentication systems. Learners will understand how to implement filters for request interception and response manipulation. The module culminates in a practical registration and login system that combines session management, JDBC integration, and servlet filters for end-to-end functionality.
