Figure B-21 Class variables
We declare the names of the JSPs we use to display the results of the program,
as well as the attribute names we use to pass the results to the JSPs.
The Servlet interface class contains the init(), destroy(), and service()
methods. The first of these methods we define is our init() method
(Figure B-22 on page 360). The purpose of the init() method is to perform the
necessary servlet initialization. It is guaranteed to be the first method to be called
on any servlet instance. The servlet implemented may choose to override this
method to perform custom servlet initialization. In our init() method, we
instantiate our loadedDate object so as to set the time of loading and also call the
superclass init() method to ensure the proper HttpServlet initialization occurs.
