Hi All,

Why do we say that struts is based on MVC as struts doesn't give us a model.

Thanks a lot! One more question about Action classes:

why to write execute method in Action's subclass?

Thanks seetharaman.

you should not put every thing into the session

Can you explain it in a bit detail?

And if it is not complusary to use actionForm but preferable, what else we can write instead of action form?

Hi All,

I am newbie to Struts. I have a doubt on ActionForm in Struts.
What is the exact use of actionForm? If it is used to store user specific data coming from HttpRequest then why can't we use HttpSession?
If it performs simple validations cant we use javacript for the same? And is it compulsary to use ActionForm?

Thanks in Advance.

Thanks A Lot!

Hi All,

I am new to java and preparing for SCJP. I have a small doubt aboout ++ operator in java.

Is it behave same as C? Or different?


class C
{
public int f1(int i)
{
System.out.println(i + "in f\n");
return 0;
}
public static void main (String[] args)
{
C obj = new C();
int i = 0;

i = i++ + obj.(i);

System.out.println("in main() "+i);
}}

Above program gives different output in C and Java.

Can you tell me why?

Thanks In Advance.
