Review Questions

What language is used to write servlets and JSP?
What is the servlet life cycle and what manages it?
What protocol do servlets and JSP use to communicate with clients?
What is the relationship between servlets and JSP?

Answers to Review Questions

Servlets are written in the Java language. JSPs on the other hand use a combination of HTML and Java. Eventually JSPs are converted into a pure Java servlet. See "Servlet and JSP History," earlier in this chapter.
The servlet life cycle refers to the loading, initialization, invoking, and killing of a servlet. The container manages this life cycle. See "Web Servers and Servlet Containers," earlier in this chapter.
Servlets use the HTTP protocol. See "Web Servers and Servlet Containers," earlier in this chapter.
JSPs are converted to servlets. First, the JSP source is parsed and a Java source file is generated. Then this source is compiled into a servlet. See "JSP," earlier in this chapter.
