One word, eh? ServletContextListener. Use a ServletContextListener to
load your properties files and pass the name to it via servlet context
parameter. There are ways to use Struts classes to initialize and
load the data, but I wouldn't recommend it when there are solutions
that are just as effective, but don't rely on Struts.
See also http://www.onjava.com/pub/a/onjava/2001/04/12/listeners.html
or google for ServletContextListener
BTW, this is the approach Spring, MyFaces, and I imagine many other
frameworks and applications use to load their data on startup.

Thank you Don,
In fact, I don't want to have the name of my properties file to be hard
coded... So I thought about the "key initialization parameters" that allowed
me to set the name of the file and the Java class to load it.
Do you think it is a right way to do it, or maybe should I think about a
Listener like in the MailReader app to load the database?
In one word, what's the best way to do it?
Thanks
