Your FormBean should be flat, meaning it should only have the attribute that
your selection box will be submitted. As for the List that you used to
populate the Options list, it should be created elsewhere in your
application and put it in the session or application scope, then you can use
the <html:options/> tag to render
you options list. this is better because you can cache this list of options
and you don't have to build the list every time the page get render. A more
advance technique that can be use is using Tiles and build your list as
component that can be declare and use anywhere in your application.
