Download PDF File in Internet Explorer w/SSL
Struts Users,
Despite the numerous posts/suggestions I have read/implemented on the
subject, I am not able to download or display existing PDF files from my SSL
struts/tomcat application using Internet Explorer.
Safari and Firefox work fine. Unfortunately it is not an option for me to
tell my users not to use IE.
The DownloadAction example/workarounds as provided by
<http://wiki.apache.org/struts/ServingPdfDocuments>
http://wiki.apache.org/struts/ServingPdfDocuments didn't work for me either.
I haven't been able to link to the files as HREFs, either. For example:
<html:link href="files/pdfs/myFile.pdf">My File</html:link>
I don't have an entry for "nocache" in the controller element of my
struts-config file. Adding the nocache parameter with a value of false had
no effect.
Any suggestions would be greatly appreciated.
Struts Version: 1.2.9
Tomcat Version: 6.0.14
Java Version: 1.6.0_05-b13
IE Version: 7.0.6000.16757

There also is/was an issue with .pdf in IE if you didn't set the content
length before trying to send it,

Maven2 archetype:generate, Struts 2
Posted by Jishnu Viswanath <ji...@tavant.com>.
Hi,
I don't know weather this thing should come in here or not, any
way I was experimenting with maven2,
When I gave mvn archetype:generate, I got a list,
I took the best suited me, Struts 2, Hibernate and Spring :)
3: internal -> appfuse-basic-struts (AppFuse archetype for creating a
web application with Hibernate, Spring and Struts 2)
It created without any problem,
Well when you start the server, I used the inbuild jetty server, mvn
jetty:run
It gave me exception saying xfire-servlet.xml is not found, ok when I
checked the WEB-INF, 2 xmls where not generated security.xml &
xfire-servlet.xml, Ok I created empty bean xml's No bean named
'springSecurityFilterChain' is defined, Well when I checked in web xml
there is a filter defined with class
org.springframework.web.filter.DelegatingFilterProxy which takes
springSecurityFilterChain, I tried to do add that but I am getting
Invocation Target Exception.

RE: Download PDF File in Internet Explorer w/SSL
Posted by gcj <ga...@comcast.net>.
After doing some additional searching, I found out it is not a Struts issue,
but a Tomcat issue. Specifically, how Tomcat appends cache control headers
when running under a secure context (SSL).
Although this isn't a problem for Safari or Firefox, it is a problem with
Internet Explorer because it prevents the user from downloading
(saving/caching) files via SSL.
See the link below for more information:
http://marc.info/?l=tomcat-user&m=111811136603781&w=2
The solution that worked for me was to add the following response headers in
my action class that extends org.apache.struts.actions.DownloadAction:
response.setHeader("Cache-Control", "cache");
response.setHeader("Pragma", "cache");
response.setHeader("Content-Disposition", "attachment;filename=" +fileName);
My struts-config action looks like this:
<action path="/filetransfer"
type="com.myproject.actions.SSLFileDownloadAction"/>
My struts link looks like this:
<html:link action="filetransfer?file=myPDF.pdf">My PDF</html:link>
Some great examples of how to implement the struts download action can be
found here:
http://wiki.apache.org/struts/StrutsFileDownload
Thanks for the suggestions/help.

What did you do, and what happened? Without a description of the
error it's hard to help.
Your post initially reminded me of a problem I had long ago serving PDFs...
Internet Explorer has a problem displaying non-HTML content over SSL
as the result of a form POST. In short, you have to send IE some HTML
before you send it the bytes of the PDF, or it will complain.
If that sounds like it, I have a very old wiki page on the topic...
http://wiki.wsmoak.net/cgi-bin/wiki.pl?NonsecureContent
(But then later you say a plain link didn't work either, so maybe not.)

How can that not work? What happens? If the link is being generated correctly then it's unlikely that it's a Struts issue. Have you tried any IE forums?
