Re: Loading resource dynamically

[Giuseppe Galli <gi...@agora.it>]

Hi alll,
just to say that you have several way to load resource dinamically, each
suitable for different situation.
If you need to load the month names in a localized manner, put your code in a
jsp file called init.jsp that
creates through <jsp:usebean a bean (with 'application' value as scope
attribute). this bean would  dinamically loads the data from the resource
file.If this file is preloaded, every jsp page and servlet in your web app can
use the bean getXXX methods, also the getMonth() method that gives you the value
'6' to put here: <struts:select property="activationMonth" value="6">

Hope this helps
Pino.
