A Study on Composition Model Design and Testing for EJB Design Pattern Based Bean Class

EJB Design Pattern 기반의 Bean Class 조립에 대한 모델 설계 및 Testing 에 관한 연구

Today, E-Business develop because, Internet diffuse rapidly. Variety function and excellence performance needs for changeable user's requirement. So, EJB comes Component's addition and modify. For Component adds Function, Existing System modifies all of the source code. In EJB Component System, but, modifies simple source code. But, Today's System don't have cleary way that assembly component and design system. This Paper used design pattern for maintain of the component. this paper describes EJB Design Pattern using Abstract Factory Pattern. And EJB Component that used Pattern, decribes advantage and disavantage.
