HTTPService sending parameters

Question

Hi,
I am looking for a way to send in a list of parameters to my
JSP. I already know how to use <mx:Request> tag, but it only
allows for a predefined number of parameters (at design time). What
i want to do is to send in an x number of parameters in, basically,
send in an XMLList contents as parameter list.
The documentation on HTTPService has a method xmlEncode() and
xmlDecode(). I could not get it to work and there aren't any
working examples out there. I guess i could serialize an XMLList
into a xml string myself and send it as one parameter field and
then parse it in jsp... or use JSON.
Is there a workable design pattern for sending complex
objects in?
If i was to use HTTPService in ActionScript, theoretically i
could dynamically add parameters to the Request object. I just
don't know how to create and use HTTPService fom AS... can someone
show me? is it hs:HTTPService = new HTTPService();
hs.request.add("key", "value"); ??
Thanks for any help.

I personaly don't agree what they do in that example you
showed (
http://www.adobe.com/devnet/flex/articles/complex_data_02.html),
that is way too much extra unnecessary fanciness that adds
additional layer of logic on both sides, flex and jsp,which does
not really give any justifiable FLEXIbility to developer
why would you want to generate xml then on server side parse
xml when you can just as easily build request parametes on flex
side iteratively and same thing on jsp (with existing servler/jsp
API ) Exaple : iterate through all or partial request parameters
with code something like this :
for (java.util.Enumeration e = request.getParameterNames();
e.hasMoreElements() ;) {
String name = (String) e.nextElement();
String value = request.getParameter(name);
