Reload resources without restarting server

[Chen, Fang]

Hi, guys, 
 
I am pretty new to Struts. I was reading the Walk Through of the struts
example from the struts installation. In the document, it is said that "You
can even reload the configuration and message resources without restarting
the container. See the end of the web.xml file for details." I do not know
where I can find how to do this. Any help will be appreciated. 
 
Thanks,
