Java EE 7 is Here! And It's Even More Suitable for the Cloud

We're excited to announce the release of Java EE 7! So what can you expect to see and how can this release benefit you? Let's take a closer look.

The main theme for this release has to do with the Cloud. The Java EE platform is already well suited for cloud environments thanks to its container-based model and the abstraction of resource access it entails; however, in this release, we have further enhanced the suitability of the Java EE platform for cloud environments.

Java EE 7 for Private and Public Clouds

Java EE 7 products are now able to more easily operate on private or public clouds. These products will deliver their functionality as a service with support for features like multi-tenancy and elasticity (horizontal scaling). Furthermore, this release will allow applications written for Java EE 7 to further experience the benefits of a cloud environment.

The "Skinny" on Java EE 7

Java EE 7 offers higher productivity, less boilerplate, richer functionality, more default options and HTML5 support in the form of WebSocket and JSON. Here are a few more things to note about this release:

  • Simplification:  You'll see revised and greatly simplified APIs. We have simplified and extended the range of the Java EE platform to encompass emerging technologies in the web space.
  • Productivity: Experience enhanced productivity by offloading the developer from common infrastructure tasks through its container-based model and abstraction of resource access.
  • Support for HTML 5: Take advantage of extended support by embracing WebSocket functionality, along with the ability to parse and generate a JSON structure. We're providing support for HTML5-friendly markup as part of JSF.
