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 Development services for established as well as emerging companies across the world.
1. Multi-platform support language and support for web-services also
2. Develop dynamic web applications for e commerce, e learning, polls, HTML forms processing, and more.
3. Combine Java technology-based applications or services to create highly customized applications or services.
The J2EE platform provides a multi-tiered distributed application model, the ability to reuse components, a unified security model, and flexible transaction control. Not only can you deliver innovative customer solutions to market faster than ever, but your platform independent J2EE component based solutions are not tied to the products and APIs of any one vendor. .
The J2EE specification defines the following kinds of components:
Servlet and Java Server Pages (JSP) components (also called Web components): These typically execute in a web server and respond to HTTP requests from web clients. Servlet and JSP pages may be used to generate HTML (or even XML) pages that are an application’s user interface.
Enterprise Java Beans (EJB) components: These execute in a managed environment that supports transactions. Enterprise beans typically contain the business logic for a J2EE application
It is always advisable for outsourcing Java to a company which houses experienced and technically qualified Java professionals which ensures best services and that too in perfect quality.
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.
The user level web application are generally created in the simple HTML, DHTML, sometimes the complex COM and Java script applets. Most of the softwares that were developed earlier were based on the client server architecture, which needed it to be installed separately in each of the user’s computer. Upgrading such web application became extremely difficult as it involved upgrading each and every machine in which it was earlier installed. Another hassle that the client server custom application development required was to license it every time you installed a web application in your computer.
Most database driven applications that are developed using open source technologies have a three-tier structure. The web application itself runs in the browser of a desktop or a laptop. Users can only access the front end of the application to input data or search strings. Java being platform independent allows applications to be accessed on any device like a pda or cellphone or any telnet device.
Enterprise Java bean application development occurs by employing a three-tier architecture consisting of a front end known as the web container, an EJB container, the third tier being the database. This three-tier structure has proved to be immensely useful for enterprise application development.
