You need to get the output writer from the servlt response, then set the
mime type and and content length on the response.

Ok, then how do I (i.e. what call do I make) redirect the output to the
browser?

Do I say something like

servletResponse.setContentType("text/html; charset=UTF-8");
PrintWriter out = servletResponse.getWriter();
...
//Processing:
//  Filter1: Parse XML
//  Filter2: Transform XML using SAX
...
out.print();
