J2EE or the Java to Enterprise Edition platform developed by Sun Microsystems stipulates the criterion for developing multi-tier enterprise applications. The J2EE platform leverages the robustness of the Java programming language that allows developers to write the code only once and execute the application on any platform. Presently more than two-thirds of development managers use the J2EE platform to develop and deploy their applications.
Businesses all over the globe have realized that they can gain a sustainable advantage over their peers by developing custom applications for their unique business needs. Quick development and deployment are required whether in-house applications for raising employee efficiency are being created or rich internet applications to cater to the specialized needs of the clients are being developed. Another issue, which is of concern to enterprises, is the portability and scalability of their enterprise applications. An enterprise application is viable only when it is easily portable across platforms and devices. Scalability is also another parameter, which decides the long-term feasibility of an application. Enterprise applications must be scalable so that they can be scaled up to accommodate thousands of users simultaneously. J2EE based enterprise applications can be executed across platforms and are functional across devices.
J2EE based enterprise applications succeed because stable J2EE standards help developers create multilevel applications with a component based approach. Existing database management systems and legacy applications can be brought under one umbrella so that the critical requirements of the enterprise can be fulfilled. J2EE, in our opinion, has a very bright future and the recent addition of interoperable web services and other new services in version 1.4 will make it even more market-friendly.
