Java 2 Enterprise Edition (J2EE), later renamed to Java EE (Enterprise Edition) and now Jakarta EE, was a set of specifications and APIs for developing and deploying enterprise Java applications. It provided a standardized, component-based approach for creating scalable, robust, and secure web applications, enterprise services, and other server-side solutions. Common uses included building web applications with servlets and JSPs, handling business logic with Enterprise JavaBeans (EJBs), managing data with Java Persistence API (JPA), and integrating different systems with Java Message Service (JMS).
