Thank you for your response.
Correct me if I'm wrong, but the way I understand is that the
HttpServletResponse is not passed directly back to the calling client
(in my case the Applet.) Instead the server container sends to the
client what is written to the HttpServletResponse writer. In my case I
send either an Image object or a string. This means that the applet
does not have access to the servlets response object. Also the
getParameter method is not defined in HttpServletREsponse. It is only
defined in HttpServletRequest which is what I think is getting confused
here.
Anyhow,
thanks again.
