Summary
Today we explored the Web tier, Web container, and Web components, and how each contributes to building Web applications. We briefly surveyed the four Web components: servlets, JSPs, taglibs, and JavaBeans, with an example to demonstrate each API. We scratched the surface of each Web component and its proper usage. Servlets were covered as delegates as well as controllers, in addition to handling user inputs. You learned JSP's main syntax and its scripting elements. JSP taglibs were explored as an extension to JSP. You learned also about the packaging and deployment of Web applications.
On Day 20, you'll learn how to create a complete Web application, and how to apply the MVC pattern as part of the JavaMail exercise.
