Java EE 7 Soup to Nuts at JavaOne 2014
Java EE 7 provides several new features to improve developer productivity and meet enterprise demands. These include WebSocket, JSON processing, simplified JMS, and more annotated POJOs. Popular Java EE 7 application servers that implement these specifications include GlassFish, WildFly, and JEUS. Various IDEs like NetBeans, Eclipse, and IntelliJ provide support for developing Java EE 7 applications.
