Problem with request.setAttribute

[Deepa Khetan <de...@gmail.com>]

Hi,
 I have a observed a peculiar behaviour with Struts. We cannot use
request.setAttribute() while passing values from JSP to Action class. It
works fine if i do it from Action to JSP. but when i use it in JSP and
retreive value in Action class, it results in null. Can anyone please
explain why this happens?

Hi,
        When you use request.setAttribute() in Action, it is the same 
request which goes to JSP also. So, you are able to get the values in JSP 
through request.getAttribute(). But when you use request.setAttribute() in 
JSP and submit the form, then a new request is generated with the values 
that are contained in the current form and that new request erases all the 
previous values. If you want to use these values in the Action also, you 
need to set them to session rather than request.
