Why do you want to be able to go back?
If it is for processing errors/ invalid values in the
submission why don't you check out the article on javaworld
on form processing in jsp?
Let me explain the basic idea
mainForm.jsp -> mainBean (request scope)
in mainBean process the stuff and generate a map with the
field name and error value.
if okay then forward to success page.
if invalid then forward to retryMainForm.jsp
in retryMainForm.jsp decleare mainBean with request scope
and get the previous fields values and error messages.
Write to me if you need an example.
