Try this. I used it for JNLP, but it should work for zip. Just
replace .jnlp with .zip
String fileName = request.getServletPath();
fileName = fileName.substring(fileName.lastIndexOf("/") + 1);
fileName = fileName.substring(0, fileName.indexOf(".")) + ".jnlp";
response.addHeader("Content-Disposition", "Inline; fileName=" +
fileName);
