Fw: Re: Problem with Tomcat 4.1 & Charset - Resolved!
Hi List!
My problem with the appended charset is resolved, thanks to Mark Sutton who
sent me his solution and told me to share it with the list if it worked out!
So after I deinstalled Tomcat 4.1.30 and turned to the new production release
5.0 everyhting worked fine!
And I can definitly say that IE can not cope with
Content-Type: "application/pdf; charset=ISO-8859-1"
it looks like it was a bug in the tomcat-server, so thanks for your time and
if somebody else has this problem:
An update helps!
Greats Mathias

Hi
I am having problems posting to the list so I thought I would mail you
directly.
I had a similar problem with PDFs and it seemed to be this bug:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=24970
that was causing the problem. I wasn't aware that this was a Windows-only
bug though. This bug was not present in 4.1.27 and only manifested itself
when I tried 4.1.29. It doesn't cause problems with version 5.0.x.
If this helps, then you might want to post back to the list.
Mark

Hi Yoav,
thanks for your suggestion, but I already tried that!
(
esponse.setHeader("Content-disposition","inline;filename=generated.pdf"
); )
But this does not work on all browsers!
On some IE Versions the adobe-plugin is loaded (you see the
splash-screen) and then the page remains white. No PDF and no adobe is
displayed!
So this does not work either!
But if I use content-disposition on the linux-server it works (as it
worked without content disposition)
I use the exact same files on the exact same data.
When I save the files look for the difference the only thing I find is
the additional charset= ... on the non working version.
Greats
Mathias
