Upload widget cocoon-2.1.11

Hi,

I want to use two upload widgets in a CForm.

Each widget will upload files to a different directory eg:

 1. images/
 2. pdfs/

Please how can I do it as the web.xml appears to only allow in

<init-param>
       <param-name>upload-directory</param-name>
       <param-value>D:\test</param-value>
  </init-param>

to set one upload directory?

Also if I set

<param-value>../test</param-value>

What's it relative to, I can't work it out?

Thanks

Peter
