  == Employee list with pure JSP (Model 1) ==
+ 
+ Our initial Model 1 JSP-based application consists of just one JSP file, simplicity itself.
JSP file contains two clearly separated sections. One section loads employees from a storage,
creates employee list to display, and stores this list in an appropriate J2EE scope, in our
case in the session. Another section of the JSP file displays employee list as rows of an
HTML table.

- Before the data list is displayed, it should be retrieved from a database and saved into
appropriate J2EE scope like request, session or application. Then the list is iterated and
its content is shown line by line. Notice JSTL 2.0 usage.
+ Distinct separation of data preparation code and markup rendering code helps with readability.
Note JSTL 2.0 usage, it greatly simplifies the markup.
