We observe that the e-business systems development frameworks tradeoff performance at the expense of flexibility. In this paper, we present a performance comparison of JavaBeans application framework with a well-known framework, Struts. JavaBeans is a flexible and extensible CBD application framework. However the flexibility and extensibility are conflicting software qualities against the performance. Our experiment results show the significance of JavaBeans application framework over contemporary CBD application frameworks and how much its performance is affected by changing schemes of the framework for achieving flexibility and extensibility.
