RE: If several JSPs share the same action mapping...?

[James Mitchell <jm...@telocity.com>]

Right, you will not know which jsp submitted the form unless you:

1. find out from the request (request uri)
2. tell the action by some hidden form var or on the url action (html)

either way you've got to create a hack to pass the correct ActionForward.


sorry for my quick (not-so-pretty) replies, I'm working on a hot project and
coding on one machine and monitoring the list on the laptop.  I'm
multi-tasking
both mentally, and physically ;)  (My alt-tab is a quarter turn to the left)
