JSP is the server-side programming technology.
The web server needs the JSP engine to process
the JSP pages Create the web page using the JSP
such as, normal page the browser sends a request
to the web server. And then the server
recognizes that request for JSP page and
forwards to JSP engine. JSP engine compiles the
servlet into an executable class.

cleanup. Three steps involved in JSP such as
parsing, turning into a servlet and compiling
the servlet. The cleanup phase defines when a
JSP is removed from use by the container.
