Curriculum

Java EE 7 Platform Overview

This foundational section delves into the core architecture of the Java EE 7 platform, providing a thorough understanding of its key components, specifications, and the intricate relationships that enable robust enterprise application development. Learners will explore the underlying structure, deployment models, and the various profiles that define the Java EE environment, setting a solid conceptual base for advanced topics.

Servlets and JavaServer Faces (JSF)

This module focuses on the pillars of web application development in Java EE. You'll explore the complete lifecycle of Servlets, from initialization to destruction, and master their configuration using annotations and deployment descriptors. For JSF, the section covers component models, event handling, navigation rules, templating with Facelets, and advanced features for building dynamic and interactive user interfaces.

Enterprise JavaBeans (EJB)

Dive deep into the world of Enterprise JavaBeans, understanding how to leverage them for developing scalable and transactional business logic. This section covers stateful, stateless, and singleton session beans, their lifecycle management, and best practices. Furthermore, you'll learn about message-driven beans for asynchronous processing and EJB timers for scheduling tasks within the Java EE container.

Java Persistence API (JPA)

Master the Java Persistence API, the standard for object-relational mapping in Java EE. This module explores the complete entity lifecycle, mapping entities to relational databases, and utilizing the Java Persistence Query Language (JPQL) for complex data retrieval. Topics also include optimizing performance with caching strategies, handling relationships (one-to-one, one-to-many, many-to-many), and integrating JPA with transactional boundaries.

Contexts and Dependency Injection (CDI)

Unlock the power of CDI, a fundamental specification for building loosely coupled, strongly typed, and reusable components in Java EE. This section covers different scopes (e.g., Request, Session, Application), using qualifiers for precise dependency injection, implementing interceptors for cross-cutting concerns, and leveraging events for asynchronous communication between beans. You will learn how CDI dramatically simplifies component management.

Java Message Service (JMS)

Explore JMS for reliable and asynchronous communication between Java EE applications. This module covers both point-to-point and publish-subscribe messaging models, enabling you to design robust distributed systems. You will learn how to send and receive messages, configure message queues and topics, and handle message listeners for event-driven architectures.

Java Transaction API (JTA)

Gain expertise in managing transactions within a Java EE environment using JTA. This section details both programmatic and declarative transaction management, focusing on how annotations simplify transaction control. You'll understand ACID properties, transaction boundaries, and how JTA ensures data integrity across multiple resources, including database operations and message processing.

RESTful and SOAP Web Services

This module provides a comprehensive guide to building and consuming web services in Java EE. You'll learn to implement RESTful web services using JAX-RS, covering resource identification, HTTP methods, media types, and advanced features like HATEOAS. Additionally, the section covers SOAP-based web services with JAX-WS, including WSDL, service endpoints, and client proxies.

Security in Java EE

Understand how to secure your Java EE applications effectively. This section covers various authentication mechanisms (e.g., form-based, basic, client-certificate), fine-grained authorization using roles and permissions, and implementing declarative security using annotations and deployment descriptors. You will learn to protect resources and ensure data confidentiality and integrity.

Java EE Application Packaging and Deployment

Master the critical aspects of packaging and deploying Java EE applications. This module details the structure of WAR, EJB JAR, and EAR files, explaining how different components are bundled. You'll also learn about deployment descriptors (web.xml, ejb-jar.xml, application.xml) and how to manage the complete lifecycle of a Java EE application within an application server.
