Summary

The combination of JavaServer Pages, JavaBeans, and tag libraries creates a powerful tool in the J2EE toolbox. By separating the presentation logic in a JSP from the business logic in a JavaBean or Enterprise JavaBean, they help to improve the modularity and design of your application. A JSP page fits well into the "viewer" part of a Model-Controller-Viewer (MVC) design pattern and can cleanly interact with the controller and model parts , such as a tag library fronting an Enterprise JavaBean. By allowing programmers well versed in HTML to focus on their job without heavy Java programming, JavaServer Pages improve the productivity of both HTML programmers and Java programmers generating the JavaBeans or tag libraries.
