Subject RE: [BUG] OutputStream is already being used for this request
Date Wed, 15 Nov 2000 04:37:17 GMT
I know that out is an implicit object in a JSP.
I did set the contenttype to image/jpeg or similar, but what I track the
issue to is that JSP does not like grabbing the output stream twice.  I have
written the servlet and get no problem, it just too bad to need to do this
just for three
line of code to dump the binary data.

By the way, some JSP FAQ use this method for dumping binary data, they
should not!
Also, for not even with the errors and stack traces, it does work, but it
may not in the
future or with other JSP servers.

Maybe you already knew this, but "out" is an implicit object in a JSP.
You probably need a response.setContentType() or the  page directive
that doe the same thing to set your output stream for binary data.
