I think this problem is due to new headers added on tomcat 4.0.3 response. It's
dificult to explain but I will try it!!!
1. IE sends the request to your servlet on a protected context.
2. Your servlet tries to send the file but tomcat adds a no-cache header.
3. IE receives the file but not show it, first, tries to find some strange files on
your server (on vti dir) and tries to get the
file from the cache.
4. But no-cache header has been send so IE has not saved the file, so IE cannot
display it.
This is an IE issue, but IE is installed on a lot of PCs, so people of tomcat project
should care about this. Maybe you can contact
with tomcat guys and ask him to add a configuration parameter to configure the headers
sended on protectec contexts.
This is a tomcat issue, not a fop issue.

Yes, I mean the security stuff and resource protection in Tomcat, the funy
thing is, i just have problems with pdf generated with FOP, if i put a PDF
file, i can see it, thats while I send my comment to FOP list.

Any way, i have a work around to this, i made another tomcat context with
out security, only with the ServletReport, and using
response.sendRedirect("myReportContext/myServletReport + parameters") from
my protected servlet and work fine.
But if any body know want to try, and found why this happend, i be happy if
let me know why.
