Basic Introduction Of Java Ee 6 Platform

It is very important for Java developers to understand the industry-standard platform

that is Java EE (Enterprise Edition) commonly used for developing Java solutions. This platform is based on solid foundation of Java Platform and has added libraries and system services that support scalability, accessibility, security, integrity and other requirements for enterprise-class applications. It has rich functionality and is a high performance platform. Its recent releases have also stressed simplicity and ease of use. Java EE 5 has made development of Java enterprise applications for Java developers. Its next release is JavaEE6 which adds significant new technologies and also some simplifications in the platform that helps in extending the usability improvements. Here we will enhance the significant features of JavaEE6.

GOALS of Java EE6:

More Flexibility in Technology Stack: This platform over the time is getting big and especially for some types of applications. To remedy this it introduces the concept of profiles, configurations of platform that are designed for specific classes of apps. Java EE6 introduces first of these profiles, web profile which is designed for web application development. It includes only those technologies that Java developers often need. Additionally it identifies other technologies as candidates for pruning.

Enhanced Extensibility: This platform focuses on including more points of extensibility and more services provider interfaces than ever before. It allows Java developers to plug-in technologies including frameworks while implementing JavaEE6. As soon as it is plugged in these technologies are very easy to use as the facilities that are built. The features that make the platform more extensible are more extensibility points, service provider interfaces and web tier features like support for self-registration. More emphasis is placed on web tier. Java developers often use third-party frameworks in their applications.

Further ease of development: In the earlier version it was definitely easier to develop various apps for Java solutions. In this version even more usability improvements is made in many areas which makes the developers task easy for developing web and enterprise apps. For example, you can use annotations to define web components such as servlets and servlet filters. Additionally it has set of annotations that makeinjectable classes much more portable.

Powerful New Technologies: Java EE 6 adds new technologies which makes the platform even more powerful and they are: Java API for RESTful Web Services (JAX-RS), Contexts and Dependency Injection for the Java EE Platform (CDI), Bean Validation

Java API for Restful Web Services (JAX-RS): This enables you to build lightweight web services rapidly conforming to representational state transfer style of software architecture. An important concept in REST is the existence of resources that can be referred with a global identifier that is URI. Data and functionality. For manipulating these resources components of the network, clients and servers, communicate through a standardized interface like HTTP and small, fixed set of verbs GET, PUT, POST, and DELETE and exchange of resources representatives.
