What sort of methods are under request.*?

Hi,
I'd like to write a general servlet to get the contents of forms in my application, then send those on to a bean to be added to the database. When I say general, I mean that, rather than writing a servlet specific to each jsp I have, I'd lke to use one for all of them. As far as I can see, this would only work if there's a method in request that can loop through all the elements in a form, like the DOM would be able to. Does request have such a method?
Are there any other suggestions for pulling this off? Or should I just bite the bullet and write a servlet for each form?
Thanks,
g.

Here's your new best friend, the Servlet 2.3 API:
http://java.sun.com/products/servlet/2.3/javadoc/index.html - it tells you all the possible methods you can call on an object.
If you click "Servlet Request"
you'll see a method called:
getParameterNames
public java.util.Enumeration getParameterNames()
Returns an Enumeration of String objects containing the names of the parameters contained in this request. If the request has no parameters, the method returns an empty Enumeration.
Returns:
an Enumeration of String objects, each String containing the name of a request parameter; or an empty Enumeration if the request has no parameters

You can loop through the enumeration and call getParameter() on each of the parameter names.
Hope that helps!!
