Java Platform, Enterprise Edition is a set of specifications, APIs, and software tools for developing large-scale, distributed, and concurrent applications. It is a part of the Java platform family, which includes Java SE, Java ME, and Java Card. Java EE provides a robust and scalable platform for building enterprise-level applications, including web applications, enterprise software, and mobile applications. The platform is designed to support the development of complex, distributed systems, and is widely used in industries such as finance, healthcare, and e-commerce.

Overview

Java EE is designed to provide a comprehensive set of tools and APIs for building enterprise-level applications. It includes a wide range of specifications and APIs, including Java Servlet, JavaServer Faces, Enterprise JavaBeans, and Java API for RESTful Web Services. These specifications and APIs provide a framework for building robust, scalable, and secure applications, and are widely used in industries such as finance, healthcare, and e-commerce. Java EE is built on top of Java SE, and provides a set of additional features and tools for building complex, distributed systems.

Specifications

The Java EE specifications define the requirements for a Java EE implementation. These specifications include:

* Java Servlet: a specification for building web applications * JavaServer Faces: a specification for building user interfaces for web applications * Enterprise JavaBeans: a specification for building enterprise-level beans * Java API for RESTful Web Services: a specification for building RESTful web services * Java API for XML-Based Web Services: a specification for building XML-based web services

These specifications provide a framework for building robust, scalable, and secure applications, and are widely used in industries such as finance, healthcare, and e-commerce.

Implementations

There are several implementations of the Java EE platform, including:

* GlassFish: an open-source implementation of the Java EE platform * JBoss: a popular open-source implementation of the Java EE platform * WebLogic Server: a commercial implementation of the Java EE platform developed by Oracle Corporation * WebSphere Application Server: a commercial implementation of the Java EE platform developed by IBM

These implementations provide a set of tools and APIs for building enterprise-level applications, and are widely used in industries such as finance, healthcare, and e-commerce.

Java EE is closely related to several other technologies, including:

* Java SE: the standard edition of the Java platform * Java ME: the micro edition of the Java platform * Java Card: a specialized edition of the Java platform for building smart card applications * OSGi: a specification for building modular applications

These technologies provide a comprehensive set of tools and APIs for building complex, distributed systems, and are widely used in industries such as finance, healthcare, and e-commerce.

History and development

Java EE has a long history, dating back to the early 2000s. It was originally developed by Sun Microsystems, and was later acquired by Oracle Corporation. Over the years, Java EE has undergone several major revisions, including:

* Java EE 5: released in 2006, added support for annotations and dependency injection * Java EE 6: released in 2009, added support for RESTful web services and CDI * Java EE 7: released in 2013, added support for WebSocket and JSON * Java EE 8: released in 2017, added support for HTTP/2 and Server-Sent Events

Today, Java EE continues to be a widely used platform for building enterprise-level applications, and is supported by a large community of developers and vendors. Oracle Corporation continues to maintain and evolve the platform, with the help of the Java Community Process.
