Simplifying Application Design Through Java Ee 6
Java EE 6 is a result of the much-felt need of today's businesses for simplified
, distributed, transactional, and portable applications that utilize the enhanced speed, security, and reliability of server-side technologies and leveraging the potential of offshore Java development. Java platform realizes a faster and easier enterprise application development where the application is designed, built, and implemented cost effectively, resource efficiently, and augmented speed making it increasingly feasible to outsource Java development seamlessly. Java EE 6 is the latest of Java platform for enterprise application development that is simple, easy, and developer-friendly.
Java EE 6 highlights
Java EE 6 simplified the design and architecture tasks of application development. You can develop context-specific apps quickly without any overhead. Java EE 6 comprises a set of independent APIs that fit well together. You can mix Java EE 6 APIs and avoid the need for infrastructure services like transactions, threading, or monitoring. The important developer task is to choose the right sub-set of APIs keeping the complexity and overhead to the minimum. Java EE 6 provides a common foundation to many Java EE platform components. The Java EE platform includes the following features and technologies
oLess XML configuration
oMore Plain Old Java Objects
oSimplified packaging
oLightweight Web Profile
oJava API for RESTful Web Services
oManaged Beans
oBean validation
oContexts and dependency injection
oJava Authentication Service Provider Interface for Containers (JASPIC)
oNew features for EJB, servlets, and JSF
Java EE 6 programming model
Java EE 6 is characterized by its simplified programming model. XML deployment descriptors are optional and can be entered as annotations directly into the Java source code file. The annotations are thus present in the program data instead of being written in a descriptor. Both the source code and annotated specification information exist side by side leading to a simplified development model for Java developers. This information access simplicity is critical to outsource Java development where Java developers need to be on the same page.
The Java EE application model uses the Java programming language and the Java virtual machine. It is designed to support applications implementing enterprise services for customers, employees, suppliers, partners, vendors, etc. The Java EE model simplifies the complex tasks of accessing multi-source data and distributing apps to multiple clients - capabilities crucial when you outsource Java development. Further, Java EE uses multi-tie-ring that deliver scalability, accessibility, and manageability for enterprise apps.
Java EE community and goals
Java Community Process (JCP) developed Java EE and is responsible for all Java technologies. Various Java EE technologies are developed by expert groups consisting of interested parties, which is a sample of effective offshore Java development. The community ensures Java technologies' stability and cross-platform compatibility. The major goals of JCP and JEE through versatile Java APIs are to
oReduce application development time
oReduce application complexity
oImprove application performance
The "So what"
Java EE 6 further extends the powerful tools of Java EE 5 for simplified enterprise application development and augments the potential for offshore Java development. Released in 2009, Java EE 6 realizes seamless design and architecture tasks and flexibilizes a structural approach to outsource Java development. Java EE 6 through its simplified development APIs, programming model, and Java community participation makes it possible to develop distributed, transactional, and portable apps that are fast, agile, and secure, leveraging the potential to onshore or offshore Java development.
