You are right. When you try to use the forward method, you'll give another
resourse the responsibility of manipulating the Response object. So you
can't use forward if in your code you've already accessed a PrintWriter or
ServletOutputStream object. May wanna try "include" instead?

Subject: AW: response already commited
To me it looks like the problem with your code is, that you try to forward
after already having committed a response to the out-object (via your
mailForm, which instantiates a PrintStream), which is not possible.
Hope this helps
