Answer Posted / 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...
