Summary

---

In this chapter we had a brief introduction and overview of JSP pages. We looked at the main features of JSP, including:

• The advantages of using JSP pages over servlets for presentation

• How JSP pages can be used to write both dynamic and static data back to the browser

• The use of JSP scriptlets and declarations for performing computations within JSP pages

• The use of JSP directives to convey messages to the JSP container, to assist it in the process of generating the page implementation servlet

• JSP actions such as include, forward, and param

• The use of JavaBeans with JSP pages

We concluded the chapter with an application that showed how JSP pages and servlets can be used together, each performing the roles they are best suited to.

We've taken a very quick look at JSP in this chapter. You can find out more about what JSP has to offer, and it can be used in your web applications in Professional JSP 2nd Edition (ISBN: 1-861004-95-8).

In the next chapter we'll turn our attention to studying the issues surrounding the security of our servlets as well as container authentication.
