aaaaaah! in a servlet, ok.
you can build a StreamResult on the Servlet response output stream.
personally, to provide the browser with the correct size of data to receive in the HTTP header, i output the XSLT result in a ByteArrayOutputStream (baos) then i use this kind of code in my servlet:
response.setContentType("text/xml");
response.setContentLength(baos.size());
baos.writeTo(response.getOutputStream());
