Answer / jagadeesh b.n
Bcoz as u all know, casting are of 2 types Upcast(implicit)
and Downcast(Explicit)in core java.....Upcasting means
converting lower datatype(int) to higher datatype(long) and
Downcast means its a viceversa of upcast...(long to int)...
As u know in struts ActionForm is a superclass where as ur
Java bean program is a simple class with private fields and
set/get methods for conversion of superclass to sublclass
we use typecasting in struts...

Answer / ravikiran(aptech mumbai)
Because The methods what we declared in a bean are not of
type ActionForm class type that's why we are type casting
and calling our getters and setters

Answer / johndoe
Acctually not realy thinking you should ask that, i mean
well ask, the answer is: to use it's methods.
But to understand it i recomend reading something about
polymorphy which explains why we're casting the action-
form, hope i understood right.
