What is Java Enterprise Edition (JEE)?

Java Enterprise Edition (JEE), now known as Jakarta EE, is a set of specifications that extend the Java Standard Edition (Java SE) with APIs and runtime environments for developing and deploying large-scale, multi-tiered, enterprise applications. It defines how to build enterprise-level software using components like Servlets, JavaServer Pages (JSP), Enterprise JavaBeans (EJB), and Java Persistence API (JPA). Jakarta EE provides a platform-independent environment, enabling developers to create portable applications that can run on any compliant application server. It is commonly used for building web applications, web services, and other enterprise software solutions.
