Submitting with request parameters

[Melissa Rabin]

Would someone kindly help me understand how one can use the struts
html:submit tag to include a parameter (& it's value) with the request?  I
am writing a simple jsp which allows the user to submit data to a database,
or clear the table entirely.   I was originally thinking of sending the
parameter via url rewriting, but I am also uncertain as to how one could do
that via a form post in Struts...

Samples or code snippets would also be useful.

Thank you so much!!
