Is your Java application running very slowly? Can they afford to keep up with the rising traffic? This article describes the development of high-performance, highly resilient JSP pages and the performance optimization of the servlet technology. The idea is to build as fast as possible and adapt to a growing number of users and their requests. In this article, I'm

useful in the development stage. However, it is very expensive in the running stage; servlet/JSP causes poor performance due to unnecessary loading and increasing the load on the class loader.
