Java EE
Java EE (Enterprise Edition) is a set of specifications and APIs for building scalable, secure, and transactional enterprise applications in Java. It provides a standardized platform for developing server-side components, web services, and distributed systems, often used in large-scale business environments. The platform includes technologies like Servlets, JSP, EJB, JPA, and CDI to handle common enterprise concerns such as persistence, messaging, and security.
Developers should learn Java EE when building robust, enterprise-grade applications that require high scalability, reliability, and integration with legacy systems, such as banking software, e-commerce platforms, or government systems. It is particularly valuable in corporate environments where standardized, vendor-neutral solutions are needed, and it supports complex transactions, distributed computing, and multi-tier architectures. Use cases include developing web applications with Java Servlets, implementing business logic with Enterprise JavaBeans (EJB), or creating RESTful web services with JAX-RS.
