Form Variables vs Session Variables

[Pavan Kumar]

Hi,

Can anyone tell me whether its better to use Action form variables or variables in session when we want to transfer data between Action class and JSP? Also please list the advantages of using either one of them.
Thanks in advance.

What Action form variables??? Are you talking about Struts here?

[Pavan Kumar]

I meant Struts Action Form.

I prefer to use variables defined on my action form. At a minimum this gives the JSP developer a place to look up the name of the properties. Also, if I had a value in my Action that I needed to display on my jsp I would store it in the request before I stored it in session.

Hello

well a normal ActionForm or ValidatorForm is like a pojo, all the simple variables should be type String , the common scope is request

but you can create special variables with scope session before load a jsp
(maybe a list for a html:select), why?, because if you working with validation and detects any error, its create a new request and lost the variable that represents a List, of course that you have a variable or property that represents the value selected of the List (i had this problem if i dont use session scope for the list)

if exist another better way, please let me know

Regards
Manuel
