RE: MessageResources

[James Mitchell <jm...@telocity.com>]

Let's bounce this on the dev list.

Struts gurus, this was in response to someone (I doubt that I'm the only
one) asking about having the resource bundle loaded from xml file(s).

(and yes....I'm well aware of the "thanks for volunteering" approach to
requests for enhancements ;)

Is this ok for pursuing further?
What kind of priority would it be?

Personally, I'd also like to be able to load the resources from a JDBC
source.


Your thoughts?

> 		<value>message value</value>
> 	</item>
> 	<!-- multiple items -->
