Java EE (formerly known as the Java 2 Platform for Enterprise) is a design platform specifically developed to support enterprise-class applications. The platform provides standardized, modular components. Automatic application of various actions, used to ensure the creation and implementation of multi-tier applications. Java EE makes it easy to scale application sizes to accommodate large business operations that have been developed in the context of smaller test environments.
This platform builds many nice features based on the standard edition, including data security, code porting, and universal enterprise resource compatibility. Enterprise Edition specifications also pay special attention to Web services interactivity (relying on the WS-I Basic Profile). The goal is to engage business users in the development and use of custom applications based on JAVA to allow in-house and web-based applications to serve employees, customers and vendors. Java EE can adapt to a variety of enterprise systems, such as legacy database management systems. Integration between various application layers (between JAVA-based applications and non-JAVA compliant resources on the web) becomes easy.
JAVA cloud where the road went?
The current version is Java EE 6, which will be released in 2012 under normal circumstances. Java EE 6 is designed for web-based environment compatibility. However, when it comes to enterprise applications, there is a big difference between the "Internet" and the "cloud." A number of technology companies have tested the water with Java EE 6 in the cloud. For example, Oracle and open source application server GlassFish v3 cooperation. The company told attendees at its 2011 cloud fair how to deploy Java EE 6 applications in a native GlassFish instance. Attendees also saw how the sample applications are deployed to a common cloud infrastructure like Amazon EC2, Elastra and RightScale. The meeting also explored how servers are dynamically allocated in some cloud environments and the pros and cons of this approach.
This year, Red Hat also announced the integration of JBoss Application Server 7 with OpenShift PaaS. This middleware server is compliant with Java EE 6 and may be used as a gateway to Java Cloud Development work. This setting alleviates some of the developer's responsibilities, like stack setup, auto-scaling, and various maintenance issues. Customers can rely on service providers to solve the problems of this work. Allow developers to focus on enterprise application code designed for Web 3.0.
Why is version 7?
Although successful in the past, the current Java EE 6 version is not actually designed for dynamic environments. Oracle's next release will fine-tune the cloud's authenticity (like multi-tenancy and resiliency). Java EE 7 will work for both private and public cloud environments. Enterprise consumers are still part of the security and control provided by the private cloud, which is also a necessary factor in locking the big business market.
Key upgrade points include:
Easy to build server-side user interface (for JavaServer)
Java API for RESTful Web Services (JAX-RS) for handling hypermedia
Java Persistence (core functionality in object / relational mapping)
Upcoming versions of Java EE are easier for enterprise-class clients to migrate to the cloud. By streamlining the process, Oracle plans to virtualize to ensure that a large number of businesses decide to make this jump. Microsoft Azure has been paved for .net client migration. As Java EE 7 matures, non-Microsoft users will no longer have serious obstacles.
