Try something like

        <%@ page language="java" contentType="application/octet-stream" %>

in the JSP page. You may want a different contentType for your data.

There may be some magic involved to get this to work. I notice that in the application that this example comes from, the content type is also set (earlier) from within the java before calling the jsp page
