JSP scripting elements let you insert code into the servlet
that will be generated from the JSP page. There are three forms:
1. Expressions of the form <%= expression %>, which are
evaluated and inserted into the servlet’s output
2. Scriptlets of the form <% code %>, which are inserted
into the servlet’s _jspService method (called by service)
3. Declarations of the form <%! code %>, which are inserted
into the body of the servlet class, outside of any existing
methods
