Exploy The EJB On J2EE- Based WSBCC

Although it has been a short time since Java was published as a new program language, it is increasingly getting favors of developers in the enterprise. The technologies related to Java emerge in endlessly. The Sun Corporation strives to make Java not only a kind of vital language but also a kind of vital enterprise development platform. Java server contains abundant technologies, while J2EE is to encapsulate the basic and scattered low layer semanteme on enterprise development level to a system based on package container. So the developer can focus on the part closely business logic and cut down the workload.EJB(Enterprise JavaBeans) is a part of J2EE. It embodies the module virtue, which is easy to transplant and encapsulate. IBM WSBCC(WebSphere Business Components Composer) system is based on J2EE criterion and can be used on multi-channel integrated development platform. It contains many Enterprise Beans. For example, it can make the bank system integration and application development easy and quick.This thesis first introduces the status quo of the software development, the conponent-frame technology —— J2EE, the related middleware technology, JSP(JavaServerPage), which builds dynamic Web-based content pages using middleware technology and EJB, complex module development technology. In the end, the author creates an application simulating the operation of drawing cash on the WSBCC development platform and explains how to build application quickly using EJB and other J2EE technologies in the system.
