Struts automatically calls setters for the form fields. So "name" calls "setName" and "ssNum" calls "setSsNum".

Hi Jeanne,

Thanks for your valuable reply!!!

But how struts will know that ssNum is being(will be) set setSsNum() method as it does not match with property name in JSP.

I mean to say is in .jsp property name is ssNum where as in SearchForm it is setSsNum().

Please help mein clearing above concept.

Thanks in Advance.

hi,
as you wrote..............
I mean to say is in .jsp property name is ssNum where as in SearchForm it is setSsNum().

Here the concept is that the property name which is given in jsp file i.e. ssNum will be autometically retrived in bean class in the variable with same name.

Now I think you are confusing in it:-
In jsp property name ssNum
In Bean class variable name ssNum

Mean both are same

But the standard syntax of getters and setters is
setSsNum and getSsNum
Here we have to use the first letter as capital. So these above two method works for ssNum.

Now I think it is clear to you.........
