J2EE, which was formerly Java Enterprise Edition (Java EE) and Java 2 Platform, Enterprise Edition (J2EE) is a set of specifications, extending Java SE 8 with specifications for enterprise features such as distributed computing and web services. These applications run on reference runtimes, that can be microservices or application servers, which can handle transactions, security, scalability, concurrency and management of the components it is deploying.

J2EE is a platform independent, Java-centric environment from Sun for developing, online building and deploying Web-based enterprise applications. The J2EE platform consists of a set of services, APIs, and protocols that provide the functionality for developing multitiered, Web-based application.
