I am afraid there is nothing like setParameter
. Infact no request instance like HttpServletRequest
or PortletRequest
or RenderRequest
etc has such method. Its not part of the specification.
There is a good discussion here about this.
So you only have uploadPortletRequest.setAttribute(key, value)
, which is more than enough for all the requirements.
Also what would be the need to do this, if you can elaborate I am sure SO users can help you.
Hope this helps.
