Why mapping Used in Java

-
Basically Mapping will configure on xml because of following reason.

> When we use multiple file on different package then that time server doesn't decide which file we execute.

> on XML we define full controlling path . like if i click on ___ Control will forward to ___- page

Hope this will help 
Thanks
