Course Overview

This course provides a comprehensive guide to developing Java EE web applications with a focus on JavaServer Pages (JSP), Servlets, and data persistence using JDBC and JPA. It is designed for Java developers who want to build robust, scalable web applications that integrate seamlessly with databases, covering everything from the basics of web development to advanced topics like session management and transaction handling.

The course begins with an Introduction to Java EE, where you'll learn about the Java Enterprise Edition platform and its key components, including Servlets, JSP, and Enterprise JavaBeans (EJB). You'll explore the role of Java EE in enterprise application development and how it simplifies building large-scale, distributed applications.

In the Working with Servlets module, you'll dive into the fundamentals of Java Servlets, which handle requests and responses in a Java web application. You'll learn to create, configure, and deploy Servlets, manage request parameters, and handle HTTP methods like GET and POST. Practical exercises will guide you through building dynamic content, managing cookies, and understanding session tracking.

The JSP Development section focuses on JavaServer Pages, which allow you to create dynamic web content using HTML, CSS, and Java code. You'll learn how to use JSP tags, expressions, and directives to build interactive web pages. This module also covers JSP lifecycle, error handling, and integrating Servlets and JSPs for effective web application development.

The JDBC module teaches you how to connect Java applications to relational databases using Java Database Connectivity (JDBC). You'll explore the basics of JDBC API, including establishing connections, executing SQL queries, and managing result sets. You'll also learn best practices for handling exceptions and ensuring data integrity through transaction management.

In Advanced JDBC Features, you'll delve into topics such as using PreparedStatements for parameterized queries, CallableStatements for stored procedures, and batch processing for executing multiple queries efficiently. You'll also learn about connection pooling, which optimizes database connections for improved application performance.

The JPA and Object-Relational Mapping module introduces the Java Persistence API (JPA), which simplifies database interactions by mapping Java objects to database tables. You'll learn to define entities, manage persistence contexts, and use JPQL (Java Persistence Query Language) for querying data. This section emphasizes best practices for designing entities and managing relationships between them.

Transaction Management in Java EE explores how to ensure data consistency and integrity in web applications. You'll learn about local and global transactions, managing transaction boundaries, and how to implement transaction handling using JTA (Java Transaction API). This module also covers key concepts like isolation levels and concurrency control.

In the Security for Java EE Web Applications section, you'll learn about securing web applications using Java EE security features. This module covers authentication, authorization, role-based access control, and securing data with HTTPS. You'll also explore how to configure security constraints in web.xml and implement programmatic security checks.

The Web Application Deployment and Configuration module focuses on packaging and deploying Java EE web applications in various environments. You'll learn how to use web.xml for configuring Servlets, filters, and listeners, as well as deploying your application to popular Java EE servers like Apache Tomcat and WildFly.

The course concludes with Best Practices for Java EE Web Development, where you'll learn to design efficient, maintainable, and secure web applications. You'll explore patterns such as MVC (Model-View-Controller), DAO (Data Access Object), and Front Controller, and how to use these patterns to improve your application’s architecture.

By the end of this course, you'll have the skills to develop fully-functional Java EE web applications that connect to databases using JDBC and JPA. You’ll be able to build scalable, secure, and efficient applications that meet enterprise standards, preparing you to tackle complex web development challenges with confidence.
