The java 2 enterprise edition came to being due because of the need to put together various java technologies into one platform. With the wide and dynamic growth of the java, language there arose a dear need to develop Java APIs enterprise standards. Java APIs is majorly constitutes various APIs which are tasked with the responsibility of providing for vendor –independent programming interfaces that facilitated access to a diverse range of services as well as systems. J2EE emerged as the Java APIs enterprise version, which explains its prolific performance in enterprise applications. The adoption of this technology therefore ensures maximum portability of business elements or components such as transactions, business as well as distributed processing.
The J2EE is designed to support a multitier type of architecture hence enhancing flexibility in design. J2EE is crucial as it aids in the reduction of complexities involved in the design, piloting, implementing, as well as administration of application components. Following are the various tiers that make up the multitier architecture of the J2EE.
The client tier is majorly responsible for the displaying of information to the end user. It does this by interacting with user who makes request which the clint tier forwards to the information system before displaying the requested information to the end user. J2EE architecture supports various types of clients, which include; java applets, java application as well as HTML clients.
The Web tier
This majorly the logic of presentation, which is generated to the user. It also accepts responses from the user via the presentation client. Appropriate response is generated by the presentation tier based on request received from the clients.
The business tier
This tier is responsible for, the main business of an application. It provides underlying business components with relevant interfaces to facilitate business process. This tier is solely responsible for the components process such as transactions, resource allocation as well as management of persistence.
Enterprise information systems tier
It is commonly referred to as EIS tier and is responsible for the management and manipulation of enterprise information systems. Such systems include; the transaction processing systems, database systems, resource planning and allocation systems as well as legacy systems.
The forgoing are the major components that make up the J2EE IT architecture. Their specialization to conduction of various task is responsible for the effective and efficient performance of the whole model. Its adoption in business enterprises is thus quite handy and beneficial to both the business and its clients.
Importance of the J2EE to ecorner
The benefits of the J2EE to the business are numerous. This application, which makes work easier for both the client and the server, should be a high recommendation to the e-corner company. The compatibility of the application gives the business the ability to develop products that can run on many systems. The J2EE ensures that the developed products will run on any system that is compatible with it, thus the high compatibility nature of the J2EE gives it an advantage to other applications. This allows the business to capture a wider clientele base.
The ease to learn the J2EE application makes it efficient to adopt since it would help to ensure a significant increase in production. The developers would also through the system build applications faster and more easily thus reducing the time needed to market the applications and cost incurred in the development of the applications.
The J2EEE also allows the vendors to develop and sell their components easily to their clients who through the J2EE also can buy the software as needed.
The business can also ensure the security of their investment by adopting the J2EE application, as it does not offer vendor tailored lock-in type of architecture but is an industry supported application standard.
The J2EE architecture will give ecorner which is an IT based, the ability to access products built on standard platforms. This then allows the company to choose products from that variety and thus ensure cost effectiveness int eh products selected due to the wide range available.
The J2EE is self-managed and therefore saves the complexity that comes with the webhosting services especially for the data based websites.
It increases on the interaction between the business and the clients through the website thus cutting on cost of employment.
