Bear, Its just incase uri location might be changed in future. You will not have to modify the jsp page. You just change a property file. We have multiple installations of our web-apps at our development facility, client place etc.
And, if you like (I don't), you can abstract the URI in the web.xml file so that, in the event of a change, only the web.xml would need to be updated. [ October 21, 2004: Message edited by: Bear Bibeault ]
