Can you make use of a ServletOutputStream object from within a JSP page?

Govind Seshadri No. You are supposed to make use of only
a JSPWriter object (given to you in
the form of the implicit object out)
for replying to clients.
A JSPWriter can be viewed as a buffered version of the stream object returned by response.getWriter(), although from an implementational perspective, it is not. A page author can always disable the default buffering for any page using a page directive as:
<%@ page buffer="none" %>
