This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
The <html:reset> tag simply creates an <input type="reset" > tag. If you're using Struts client side validation, it also disables validation when this button is pressed. Since clicking this button does not cause a form submission, you don't have to do anything on the server side. It just causes the form fields to be reset to their initial value.
