Enterprise Java Beans and JPA: Building Scalable Java Applications

Building scalable, multi-tier enterprise systems requires a solid understanding of how components manage transactions, security, and database persistence. This course provides a clear, text-based path to mastering Enterprise Java Beans (EJB) and the Jakarta Persistence API (JPA) within the modern Jakarta EE ecosystem. You will transition from writing simple Java programs to designing robust, transaction-safe backend systems. By understanding the core lifecycle of enterprise components and how they interact with databases, you will gain the skills needed to develop enterprise-grade applications. What you'll learn: - Understand the core architecture of Jakarta EE, including EJBs, containers, and application servers. - Create session beans to manage business logic and state efficiently. - Implement database operations using the Jakarta Persistence API and Object-Relational Mapping. - Configure container-managed transactions and security policies to protect your application data. - Apply modern Java testing practices to verify enterprise beans and persistence layers. - Deploy scalable applications to compliant application servers using modern build configurations. The course starts with fundamental concepts of enterprise architecture and component lifecycles before guiding you through practical, text-based code structures. You will explore step-by-step written explanations of transaction management, dependency injection, and database mapping. This course is designed for Java developers looking to step into enterprise-level development. No prior experience with EJBs or JPA is required, as we begin with foundational definitions and basic application setup.
