Re: [Raw newbie] Struts/JSTL - A cople of urgent question (Message resources)

[Joe Germuska <Jo...@Germuska.com>]

It may not be a Struts question, but if you're using a post-1.1 
Struts build, you may find the DigestingPlugIn an easy way to put 
together lists for use in menus.

The DigestingPlugIn simply uses Digester to process an XML file and 
put something in the application context; the simplest possible use 
case is to use one plugin for each menu you need and put lists of 
LabelValueBeans into application context.  (You can get fancier if 
you want.)

Then you'd have a separate plugin for each domain of measurement 
(distance, area, volume, etc) or locale.

You could probably actually use the DigestingPlugIn without post 
Struts-1.1, except that you'd need your own LabelValueBean class (the 
one in Struts lacked a no-arg constructor at the time of the 1.1 
release.)  If you just want it in a package, you could grab the 
version from http://demo.jgsullivan.com/struts/ which is the same in 
spirit.

Hm.  Now that I read a little more, I wonder if you're also looking 
for a localization solution?  In any case, using the DigestingPlugIn, 
you could make a slightly smarter bean which was localized.  It would 
take more code, but nothing too hard to put together.
