newbie question on form handling

[Joe Dowd <jo...@hotmail.com>]

It looks to me as though Struts requires an actionClass for every logical 
request. I have a form that contains a few tables where some cells values 
are dependent upon user supplied value elsewhere in the same form.  I want 
to update these cells as the user moves through the form supplying the 
needed values.  It will be necessary to hit the server to retrieve values to 
be displayed in the cells (perhaps via a hidden submit button).  Is there a 
good technique for updating a table(s) in a form based on the dynamic 
content provided by the user w/in the same form?

Thanks
jd
