Although Oracle has been mostly quiet lately about the progress of its enterprise Java overhaul, that is likely to change soon with the impending arrival of Java Platform, Enterprise Edition 8, better known as Java EE 8.

The upgrade retools enterprise Java for cloud and microservices environments. A vote on the Java Community Process specification for Java EE 8 is under way and is due to be completed on August 21. Java EE 8, the official specification states, is about simplification while extending the range of the platform to accommodate emerging technologies in the cloud and web. The specification also emphasizes HTML5 and HTTP/2 support.

Java EE 8 will support a multitude of Java technology specifications, including:

  • JSON-B (JavaScript Object Notation Binding), providing a binding layer for converting Java objects to and from JSON messages.
  • Updates to JSON-P (JSON Processing API), improving the object model.
  • JAX-RS (Java API for RESTful Web Services) 2.1 reactive client API.
  • JAX-RS support for server-sent events, offering a one-way channel from a server to a client.
  • HTTP/2 support in Servlet. Java Servlet provides a programming class to extend server capabilities.
  • Java EE Security API, accommodating cloud and PaaS paradigms.
  • Bean Validation 2.0, leveraging Java 8 language constructs for use in validation. Bean Validation enables expression of constraints on object models using annotations.
  • JavaServer Faces 2.3, for building server-side user interfaces.
  • CDI (Contexts and Dependency Injection) 2.0, emphasizing asynchronous events.

Java EE upgrades to come faster

Java EE 8 will be followed next year by Java EE 9, as part of a two-phase effort to retool the platform for modern-day cloud and microservices deployments. Java EE 8 is centered on accommodations to configure services and on health-checking to manage services. The follow-up EE 9 release is slated to promote deployment of smaller units of services and a reactive programming model for building large-scale, event-based systems.
