PDF files under IE 5.0

[Franck LANTRES <fr...@fr.renault-sport-f1.com>]

Hi,

I know that my question is a little out-of-scope of this mailing-list : we have
problems with PDF files generating by servlets.
Our servlet generates PDF files using 'fop style sheets' and put the result in
the body of the HttpServletResponse. The problem is that the PDF file is
correctly viewed using Netscape (on Linux) but not using I.E. 5.0 (on WinNT) :
it seems that IE try on download this file from the server (same problem saving
the 'file' on local disk).

Here is the code :

String res = (String) resultString;
mimeType = mimeType + ";charset=ISO-8859-1";
sres.setContentType(mimeType);
sres.setContentLength(res.length());
sres.setBufferSize(res.length());
sres.setDateHeader("Expires", 0L);
sres.setHeader("Cache-Control", "no-cache");

PrintWriter out = sres.getWriter();
if( res != null)
	out.print(res);
out.flush();
out.close();
sres.flushBuffer();



Environment :
- Tomcat 4.0 Beta 5,
- Linux 2.4 (SuSE 7.1)
- JDK 1.3.1

Have you an idea ? Thanks a lot.

Franck.

I finally find the solution : just reset the buffer using the
HttpServlet.reset() method !!!!
Thank you IE :-(

from memory ie tends to not pay full attention to mime-types.  For
example if you have a servlet which can be requested by .jpg and generates
an image with an binary stream mimetype IE seems to display it, even
though by rights it should save it (this is an old example from a year
ago).  So thinking along the same lines, if you made the servlet match
something.pdf then maybe it would work?
