Oracle on 12th June, 2013 released the 7th version of Java Enterprise Edition.
Java EE7 has been released with an aim to deliver better development capabilities and scalability along with support for HTML5 applications. It is the first version that has been solely released under Oracle’s sponsorship.
Java EE has been introduced as an enterprise application deployment platform that provides ease of development, deployment, and management of multi-tier, server-centric applications. Java EE6 was the last release which contained open source APIs and frameworks that provided seamless and flexible development and integration capabilities. With an aim of taking this further, Oracle released Java EE 7.
What is Java EE7?
Java EE7 is a scalable infrastructure that is a joint outcome of extensive review and collaboration between hundreds of engineers from more than 30 companies within the Java Community Process (JCP) and the GlassFish Community.
Why is Java EE 7 released?
Java EE 7 has been released tomainly provide support for emerging technologies like HTML 5 and provide the below mentioned benefits to the developers
- Better collaboration to different platforms with Java
- Faster coding capabilities refraining overheads
- Community to offer feedbacks and reviews for the ongoing development
- Maintaining the quality and improving the security of the applications developed in Java
What’s New in Java EE 7?
Support for HTML 5 Applications
Java EE 7 features a foundation for developing HTML 5 applications since the demand of HTML 5 is accelerating. The support for the HTML 5 applications in Java EE 7 has been provided by
- Developing Web Sockets for removing problems of low latency and bi-directional communication
- Simplifying Data Parsing with JSON processing
- Supporting concurrent users for RESTful web services with JAX-RS2.0
Better Developer Productivity
Java EE 7 provides significant improvements in developer productivity along with seamless developer experience and simplified architecture with an integrated platform by
- Removing boiler plate codes that are required to write business logics
- Adding Annotations to reduce the requirements of XML configurations
- Cutting the old technologies
Scalability to Meet the Demands of Enterprise
Java EE 7 also aims to meet the demands of enterprises such as
- Breaking batch into chunks for managing performance of OLTP
- Defining concurrent tasks for improved scalability
- Developing batch applications for integrating the current system with Java EE
Other than these, Java EE 7 features Contexts and Dependency Injection (CDI) Beans that significantly reduce the coding required to send and receive messages. It also includesan Integrated Development Environment (IDEs) such as NetBeans and Eclipse for early birds who wants to start with Java EE 7 immediately.
With better productivity and scalability, Java EE7 promises to reduce the hiccups in the application development environment especially for the HTML 5 platform.
Oracle has also planned to provide features of Cloud Computing and PAAS as an enhancement to support the cloud based applications. However, that will be available in Java EE8. Till that make the best use of new and freshly release Java EE 7.
