Understanding Enterprise JavaBeans (EJB): The Backbone of Java EE Applications
Enterprise JavaBeans (EJB) is a key technology in the Java EE (Jakarta EE) framework, designed to help developers create scalable, secure, and robust enterprise-level applications. EJB abstracts many complexities of building distributed applications, allowing developers to focus on writing business logic rather than managing low-level infrastructure details. In this article, we’ll delve into the various aspects of EJB, its role in Java EE, and how it supports enterprise applications.
What is Enterprise JavaBeans (EJB)?
EJB is a server-side component architecture that enables developers to build modular applications using Java. It serves as a foundation for developing large-scale, distributed, and multi-tiered applications. By leveraging EJB, developers can easily create reusable business logic components that encapsulate complex processes, making it easier to develop and maintain applications.
Key Features of EJB
1. Component-Based Architecture
One of the primary advantages of EJB is its component-based architecture. This design allows developers to break down applications into smaller, manageable pieces, known as beans. Each bean represents a specific…
