You need to be using
<jsp:include page="/foo.html" />
Under the covers getOutputStream during the include. But a getWriter was
already called. Once you call getWriter - you can't call getOutputStream, or
you get the ISE.
jsp:include gets aroung this by wrapping the response and wrapping
getOutputStream to avoid this issue.

----------------- x.jsp --------------------------
foo
<%
RequestDispatcher rd =
request.getRequestDispatcher("/foo.html");
rd.include(request, response);
%>
test;
-----------------end---------------------------------
------------- start foo.html ------------------------
This is a foo page, with some dummy html

Now, when i try to get "x.jsp", I get:
