Build the skills to design and implement dynamic web applications with Java Servlets and JDBC in a structured, hands-on learning experience. This course introduces the fundamentals of Java EE, servlet architecture, HTTP request handling, and Tomcat configuration before guiding you through building scalable servlet-based applications using the MVC architecture. As you progress, you will learn how to configure servlets, manage application context, process client requests, and maintain user state through session tracking, cookies, hidden fields, URL rewriting, and HTTP sessions. You will also explore relational database concepts and SQL, then integrate databases with servlets using JDBC to perform secure CRUD operations. The course concludes by implementing servlet filters and developing a complete user registration and login system that combines authentication, session management, and database connectivity into a deployable web application. Designed for aspiring backend developers, Java programmers, and learners interested in Java web development, this course emphasizes practical implementation while strengthening your ability to analyze architectures, apply configuration techniques, manage user sessions, integrate databases, and build complete servlet-based applications. By the end of the course, you will have the knowledge to develop Java web applications that combine servlets, JDBC, SQL, and authentication within the Java EE ecosystem.

Syllabus

Introduction to Servlets and Server Setup

This module introduces the foundational concepts of Java EE (J2EE) and the role of servlets in web applications. Learners will gain a practical understanding of servlet architecture, how to set up the environment using Tomcat, and implement basic servlet functionality through lifecycle methods and HTTP request handling. It builds the core knowledge required to develop and deploy servlet-based applications in a Java EE environment.

Servlet Configuration and Context

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.

MVC Pattern and Request Handling

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.

Session Tracking and State Management

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.

HTTP Sessions and Cookie Management

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.

Database Integration and SQL Essentials

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.

JDBC Integration with Servlets

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.
