Welcome to Unit 4: JSP & View Technologies
Welcome to Unit 4 of Jakarta EE & Web Architecture, where we explore Jakarta Server Pages (JSP) and the technologies used to create dynamic, interactive, and user-friendly web application interfaces.
This unit introduces students to the fundamentals of JSP, its architecture, lifecycle, syntax, implicit objects, scopes, Expression Language (EL), and JSTL. The concepts are explained in a simple, structured, and practical manner, helping beginners understand how JSP works as the view layer of a Java web application.
You will begin by learning the JSP Architecture and Lifecycle, followed by JSP syntax and different JSP elements used to generate dynamic web content. You will also explore Expression Language (EL), which provides a simple way to access and manipulate data within JSP pages.
The unit further introduces JSTL (Jakarta Standard Tag Library), which helps developers perform common tasks such as conditions, iteration, and data processing without writing excessive Java code inside JSP pages.
You will also learn about JSP Implicit Objects and JSP Scopes, along with techniques for handling sessions and cookies. These concepts are essential for maintaining user information and application state across multiple web requests.
The unit concludes with Error and Exception Handling in JSP and the integration of Servlet + JSP using MVC Architecture, demonstrating how business logic and presentation logic can be separated to create well-structured and maintainable Java web applications.
📚 In this Unit, You will Learn:
🔹 Introduction to JSP
🔹 JSP Overview
🔹 JSP Architecture
🔹 JSP Lifecycle
🔹 JSP Syntax and Elements
🔹 Expression Language (EL)
🔹 JSTL – Jakarta Standard Tag Library
🔹 JSP Implicit Objects
🔹 JSP Scope
🔹 Request Scope
🔹 Session Scope
🔹 Application Scope
🔹 Page Scope
🔹 Session Handling in JSP
🔹 Cookie Handling in JSP
🔹 Error Handling in JSP
🔹 Exception Handling
🔹 MVC Integration using Servlet + JSP
🔹 Separating Business Logic and Presentation Logic
🔹 Developing Structured Web Applications using JSP and Servlets
Throughout this unit, students will learn how JSP works as the presentation layer of a Java web application and how it can work together with Servlets to process requests, manage application data, and display dynamic content.
By the end of this unit, students will be able to create dynamic JSP pages, use EL and JSTL, work with implicit objects and scopes, manage sessions and cookies, handle errors and exceptions, and integrate JSP with Servlets using the MVC architecture.
These skills will provide a strong foundation for understanding modern Java web application frameworks such as Spring MVC, Spring Boot, Thymeleaf, RESTful Web Services, and enterprise application development.
