I have a sample Servlet (sources included) available from my site
under
http://www.christianbollmeyer.de/dl?downloadFile=DownloadServlet.war
which should contain everything desired, including GZip compression.
Considering the code example given: out is a Writer, a text stream.
For delivering binary contents, you have to use another kind of
stream (the exact flavor depends on whether it's compressed,
buffered and the like). The sources should tell you all you need
to know about these matters.
