Subject Re: struts vs ibatis - Integer type
Date Mon, 02 May 2005 19:28:29 GMT
The only way to make that "clean" is to push the translation effort
into your ActionForm and nest your real beans in the ActionForm. you
would then have a String value that you convert and set into your
nested bean. The other option is to write a different BeanUtils
Converter implementation for numerics and register it

I would personally avoid cluttering up your domain bean with faux
setters and getters.
