Thanks to Stan and Ulf for reply.
Ulf, your link is very informative and useful. I see the issue now. After going thru the materials there, I found one of my fear is true - If we go through custom ResourceBundle, we will end up having one class for each locale (and variant) and add more locale will require more coding and deployment. Your link has one hint to use
struts messageresource utility to achieve the same. As we will also use Struts for web-tier front controller, I will explore this option.
I will keep you posted as things are unfolded.
