In Struts, Global forwards are the action forwards which 
can be forwarded from any action. 

Consider, log out link, that will be present in all the 
page, so, u can't write a forward in all the action mapping 
and check. so, struts is using global forwards, whatever 
forward declared in the global forwards can be visible to 
all action mapping. We will use global forwards in 
situtaions like logoff, error page.

---------------------------------------------------------

The question is not clear, is it Struts Navigation Flow ?
Then let me know, i will post the answer

what if a action has the same forward name as a global 
forward. which one will be picked for the action mapping?..
