Hi there,
I have the following problem: in order to prevent the web-browser
from using cached versions of a jsp, we plan to add some unique

Hi,
Does anybody have an experience of properties that are not in the

create a new subclass of ResourceBundle (like PropertyResourceBundle)
but is it an easy task ? Do you know any example of such a thing ?
Thanks
Sebastien

We have the same problem. We forward our "success" to a frameset (jsp) with
