Summary

JSP tag libraries coupled with good design patterns enable you to more easily maintain and extend a Web-based application. With the additional power of the WebLogic Portal Webflow, the separation of presentation and business logic is more complete. Of course, tools are not a substitute for good design practices. Many design patterns can also be used when you're dealing with JSPs and servlets. For example, the Singleton pattern is not Java specific. It can be applicable to J2EE development at times. But by combining these powerful tools with good design patterns, you can achieve a solid, maintainable system.
