Java Enterprise Edition 7 (JEE7): Features and Specifications
The latest version of Java Enterprise Edition (JEE) called JEE 7 was recently launched by the Oracle and the Java Community Process (JCP) members along with Java EE 7 Software Development Kit (SDK). With this, the Java developers and engineers will not get the access of Java EE 7 SDK and the open source GlassFish 4 application for which they were waiting for a long time.
Java Enterprise Edition 7 (JEE7), has made many improvements in various specifications. Some of the major, improvements which ahs been integrated in JavaEE 7 are:
The major emphasis laid in Java EE 7 is on HTML 5 . JEE 7 have accommodated the use of HTML 5 to deliver HTML5-scalable applications to the Java engineers. Thus, JEE 7 is much more simplified to enhance the productivity and support for creating modern, multimedia-enriched Web applications. Moreover, Oracle is offering the support for the same via accommodations for WebSocket and JSON.
In order to improve the productivity of the developers, JEE 7 has been integrated with several alluring features such as simple application architecture integrated with unified platform, use of dependency injection and default resources to reduce boiler-plate code, broadens the use of annotations to increase efficiency; and enhances application portability with standard RESTful Web Services client support.
Java EE 7 in order to meet the demanding enterprise requirements has come with many advance features like breaking down batch jobs into manageable chunks for uninterrupted OLTP performance. In addition to that, JEE 7 defines the multithreaded concurrent tasks easily for enhanced scalability. Managed bean alignments have been improved in this version providing the transactional applications with more choice and flexibility.
The Java Message Service (JMS) 2.0 has also been updated in order to improve usability through annotations and Contexts and Dependency Injection (CDI) Beans support. Thus, the concept of upgradation is actually reduce the code required to send and receive messages.
Moreover, Java EE 7 easily runs applications on both private and public clouds. This also defines metadata descriptor to describe PaaS execution environment like multi-tenancy, resources sharing, quality-of-service, and dependencies between applications
JEE7 has adopted the standards like HTML 5 , WebSocket, JSON and have a standards-based API for each one of them. In addition to that, it has also worked in removing the inconsistencies between Managed Beans, EJB , Servlets , JSF , CDI, and JAX-RS.
JavaEE 7 also enabled to integrate JAX-RS 2.0 in the Web Profile, revised JMS 2.0 API, Concurrency Utilities for Java EE (JSR 236) and JCache (JSR 107).
Thus, the latest Java EE 7 SDK offers wise range of scope for the learners to learn the latest Java EE technologies. In addition to that, the platform also provides the facility to the Java engineers who intend to begin with Java EE 7 release on immediate basis. They can leverage upon the NetBeans Integrated Development Environment (IDE) 7.3.1, designed to support the latest Java EE 7 features, including HTML 5 and Eclipse Kepler (4.3).
