Re: RESEND: RE: Load message resources from DB???

[Nic Werner <we...@sonoma.edu>]

Reading from the 'Jakarta Struts Cookbook' by Bill Siggelkow, he 
discusses this problem. "You want to store all labels,messages, and 
other static text in a database rather than a properties file, while 
still being able to access the values using the bean:message tag"

If this is what you're looking for, go to: 
http://prdownloads.sourceforge.net/struts/OJBMessageResources.war.zip

The only date I can find on this is 2003 however. More on OJB is here 
:http://db.apache.org/ojb/
