The real problem is that the JSP will have call response.getWriter(),
telling the container that it's going to use the JSPWriter to output its
response. Once you've done that you can't call getOutputStream(). Calling
getOutputStream() results in an IllegalStateException.
If you want to stream back a file use a servlet!
