Java Enterprise Edition (Java EE), formerly Java 2 Platform, Enterprise Edition (J2EE), currently rebranded as Jakarta EE, is a set of specifications, extending Java SE 8 with specifications for enterprise features such as distributed computing and web services. Java EE applications are run on reference runtimes, that can be microservices or application servers, which handle transactions, security, scalability, concurrency and management of the components it is deploying. Java EE is defined by its specification. The specification defines APIs (application programming interface) and their interactions. As with other Java Community Process specifications, providers must meet certain conformance requirements in order to declare their products as Java EE compliant. Examples of contexts in which Java EE referencing runtimes are used are: e-commerce, accounting, banking information systems. == History == The platform was known as Java 2 Platform, Enterprise Edition or J2EE from version 1.2, until the name was changed to Java Platform, Enterprise Edition or Java EE in version 1.5. - read more on Wikipedia
