java.lang.IllegalStateException: "getOutputStream()" has already been called for this response

Hi,
I have this error above when i load the same servlet in my webapp.
My Code looks like following :
my servletA is :
response.setContentType("text/html; charset=ISO-8859-1");
PrintWriter out = response.getWriter();
out.println("test");
out.println(....a form who submit to servletControl....);

my servletControl is :
if(ok)//call servletA
RequestDispatcher rd2 = request.getRequestDispatcher("servletA");
rd2.include(request, response);


In first i call servletA.
The result is test and a form to submit to servletControl
In second i submit the form.
The result is
java.lang.IllegalStateException: "getOutputStream()" has already been
called for this response

Thanks you for your help
