Processing Identically Named Form Fields?

[Jason Ferguson]

I can't try this for myself for a few days, but would like to try to find out so that I don't waste my time when I can do it.

Supposing I had a JSP with two identical text input fields:

<form action="/processingServlet">
<input type="text" name="serialNumber" />
<input type="text" name="serialNumber" />
<input type="submit" value="Add Serial Numbers" />
</form>

When the form is submitted to the ProcessingServlet, what would be in the HttpServletRequest for serialNumber? An array, or nothing?

Again, I'd try for myself, but it will be a few days before I can.

The HTTP request will have both name/value pairs. But you don't care about that unless you are parsing the request yourself.

To get both values as an array, be sure to use the getParameterValues() method.

Thanks Bear (yet again). Now that you point out getParameterValues(), it seems like I asked a dumb question.

If you learned something you didn't know, how is it dumb?
