3) demonstration of file upload

The call to request.getParameterValues("chkbox") should be returning
null, not throwing an exception.
Anyway, if you want to make sure you have a non-null array with 0 or
more elements, you could write a scriptlet like:
%
String[] chkboxes;
if( request.getParameter("chkbox") == null ) {

One thing to remember is that JSP pages were designed for *text* output,
like text/plain, text/html, or text/xml. Binary data should be output
by *Servlets*, not JSP's.

You don't need to rely on the servlet engine for this, and you certainly
don't need to hard-code these values in any of your classes. You should
implement a singleton design pattern "properties" class that loads
itself with information from a .properties file -- a fairly simple
wrapper around
