  • Transition from Java EE to Jakarta EE? EE Conclusion What Happened and What You Need to Know
    Search Java Magazine Menu Topics Issues Downloads Subscribe Transition from Java EE to Jakarta JAVA EE EE What Has Been Going on with Java Transition from Java EE to Jakarta EE? EE Conclusion What happened and what you need to know by Arjan Tijms February 27, 2020 Java EE is undoubtedly one of the most recognizable frameworks for server-side Java. It essentially kick-started the industry for using Java on the server, and it goes all the way back to the very beginnings of Java in 1996 with Kiva Enterprise Server (GlassFish) and the Tengah application server (the Oracle WebLogic Server ancestor). Note that here, the word Tengah refers to an administrative region in the center of the island of Java in Indonesia. Java EE, or J2EE (Java 2 Enterprise Edition) as it was known before, is perhaps best known for its Java Servlet specification and for servers implementing that, such as Tomcat and Jetty. These are often called servlet containers. Although there are alternatives, many server applications and third-party frameworks are based on the Java Servlet specification. Besides this specification, Java EE in later years became known for its specifications for persistence (Java Persistence API [JPA], mostly via Hibernate), REST (JAX-RS), WebSocket, and a slew of smaller specifications such as for transactions (Java Transaction API [JTA], mostly used under the covers by JPA), for validation (Bean Validation), and for JSON (JSON-P and JSON-B). In practice, some applications that might not seem to be classified as Java EE applications might use a variety of Java EE APIs.
