What is "jee"
JEE (Java EE or Java Platform, Enterprise Edition) is a programming platform for servers in the Java programming language.
The platform provides an API and runtime environment for the development and execution of enterprise software, including network and web services, and other large-scale, multi-tier, scalable, reliable and secure network applications.
Java EE extends the Java Platform, Standard Edition (Java SE), providing an API for object-relational mapping, multi-layered and distributed architectures, and web services. The platform incorporates a design largely based on modular components running on an application server.
Software for Java EE is primarily developed in the Java programming language. The platform emphasizes the convention on configuration and annotations for configuration.
