Java EE

The Java Platform, Enterprise Edition or Java EE is a set of specifications whose implementations are mainly developed in Java programming language and widely used in Web programming.

Software implementing this specification is referred to as Referencing Runtimes Java EE. Previously they were called application servers. The name change from application server to runtime referencing is due to the fact that, with the microservice architecture, an autonomous Java application is launched, with no need for application servers. The implementation can be total (in this case called Full Platform) or limited to the Web Profile, or the subset of specifications that has been specifically designed for web applications.
