Welcome to Unit 3: Servlets & Web Components (Jakarta EE)
Welcome to Unit 3 of Jakarta EE & Web Architecture, where we explore Servlets and Web Components, one of the fundamental technologies for developing dynamic and interactive Java web applications.
This unit provides a strong practical foundation for understanding how Jakarta Servlets receive client requests, process application logic, communicate with databases, and generate dynamic responses. Each concept is explained in a simple, structured, and beginner-friendly manner with practical examples.
You will begin by learning the basics of Servlets, Servlet Architecture, and the Servlet Lifecycle. You will also explore the Jakarta Servlet API (jakarta.servlet) and understand how Servlet components work inside a web container such as Apache Tomcat.
The unit further explains how to develop Servlet-based web applications using Maven, handle client requests and responses, and implement Session Management to maintain user information across multiple requests.
You will also learn important session management techniques such as Cookies, URL Rewriting, and HttpSession, followed by Servlet Collaboration, Filters, and Listeners. These concepts are essential for building structured, secure, and maintainable web applications.
Finally, you will explore Annotation-Based Configuration and learn how to implement the MVC (Model-View-Controller) Architecture using Servlets, helping you understand how professional Java web applications can be organized into separate components.
📚 In this Unit, You will Learn:
🔹 Servlet Basics
🔹 Servlet Architecture
🔹 Servlet Lifecycle
🔹 Servlet API –
jakarta.servlet🔹 Developing Servlets using Maven
🔹 Handling Client Requests
🔹 Handling Client Responses
🔹 Request and Response Processing
🔹 Session Management Techniques
🔹 Session Management using Cookies
🔹 Session Management using URL Rewriting
🔹 Session Management using HttpSession
🔹 Servlet Collaboration
🔹 Filters
🔹 Listeners
🔹 Annotation-Based Configuration
🔹 MVC Architecture using Servlets
🔹 Building Structured Web Applications using Servlet Components
Throughout this unit, students will understand how Servlets act as an important link between the client, web server, business logic, and database. Practical examples will demonstrate how individual Servlet components work together to create dynamic web applications.
By the end of this unit, students will be able to create Servlet-based web applications using Maven, handle HTTP requests and responses, manage user sessions, implement filters and listeners, use annotations, and design applications using the MVC architecture.
These skills will provide a strong foundation for advanced Java web technologies such as JSP, JSTL, Hibernate/JPA, Spring Framework, Spring Boot, and RESTful Web Services.
