How about having a HTML wraper class that represent a HTML control that will
generate all
the HTML tags for a particular control when calls toString(). For example you can
have a
class call HtmlSelectionBox that might be extended for a general HtmlControl class
that can
be constructed with a Collection of objects, and implements all the accessor an
multator
methods that a JSP deverloper can calls to set all the attributes of a selection
box, and the
toString() methods get calls, it will iterate to the entire collection and generate
all the HTML
tags and attribute for that particular control.
