Others have described how you configure this to make it happen. You might
also be interested in the actual code that is used -- it's in the
processPopulate() method of ActionServlet (Struts 1.0) or RequestProcessor
(Struts 1.1). Basically, Struts creates a Map of all the request
parameters, and passes it to the BeanUtils.populate() method which uses
Java reflection to call the setter methods for each of the properties.
