Build practical skills to design and implement dynamic web applications using Java Servlets and JDBC. You’ll begin with Java EE architecture, servlet fundamentals, lifecycle methods, HTTP GET and POST handling, and Tomcat server configuration. You’ll then use ServletConfig and ServletContext to manage initialization settings and shared application data. As you progress, you’ll apply the Model-View-Controller (MVC) pattern, manage request flow with RequestDispatcher, and choose between forwarding and redirection. You’ll also generate dynamic HTML and maintain user state using cookies, hidden fields, URL rewriting, and HTTP sessions. Database-focused lessons introduce relational database concepts, SQL commands, transactions, DDL, DML, and constraints before connecting servlets to databases with JDBC for CRUD operations. Designed for aspiring backend developers, Java programmers, and learners interested in Java web development, this course emphasizes guided, hands-on implementation. You’ll configure and deploy servlet applications, manage sessions, authenticate users, integrate relational databases, and implement servlet filters for request interception. The course culminates in a complete registration and login system combining Java Servlets, JDBC, SQL, authentication, and session management—giving you an end-to-end application that connects the course concepts in practice.

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.
Filters and Authentication Projects
- 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.
