You might get lucky on some containers, but you can be assured that writing binary output from a scriptlet is not guaranteed to be portable. Indeed, you're more likely to cause an IllegalStateException, because the servlet container won't let you call getWriter() and getOutputStream() on the same response. > I've seen people doing just ridiculous things with JSPs, some > of them routinely putting a <% at the top and a %> at the end, > and then went on happily putting everything imaginable in-bet- > ween, usually with lengthy <%@ page import="[xy]" %> state- > ments on top.
