keep the data in the form in session??

[Matt]

I have MyForm.jsp for the form, and MyAction.jsp that process the
request.
MyAction.jsp will interact with another system, if it fails, then it
will show MyForm.jsp with the data entered by the user again.
Everything is in the same browser.

In my case, should I keep the data in the session, so that it can go
back? Maybe I should
use <jsp:forward> tag also?

Another group on JSP I think.
<jsp:forward> and request.setAttribute or something to signify the
error?
So, MyForm.jsp checks for the error and pastes the data back in for
editing. setAttribute to pass dat along versus getParameter to get
form fields.

If you stick it in session then MyForm.jsp has to pull it back out.
Extra work to clean up.
