Re: IE6 and download problem using tomcat java servlet
Thanks for your help. Your suggestions did not seem to make any difference. However, I got the application to work when making the request from the http request a HREF=http://.../download?fileid=353;. This same request did not work when putting the http request in the address field of explorer and hitting go (except after the initial login). I suspect it is due to security restraints configured in tomcat server, but not exactly sure.

IE6 and download problem using tomcat java servlet
I am having a problem downloading a jpeg file from a tomcat java servlet to Internet
Explorer 6.0. I have changed the file extension to zzz to force the download
prompt. If I restart tomcat(version 4.1.x), the download works fine the first
time. The correct filename video.zzz appears on the prompt and I can hit save and
it will prompt me as ti where I want to save the file. However, after the first time
I get a download prompt with an incorrect filename (the filename is the http query
request). If I select save,then it does not prompt for a location to save and I
immediately get error Internet explorer was not able to open the requested site.
Is there something else that needs to be set in the http header?
Here is the piece of the java servlet that is issueing the download:
response.setContentType(APPLICATION/OCTET-STREAM);
response.setHeader(Content-Disposition,
Attachment;Filename=\video+videoid+.zzz\);
String size=Integer.toString((int)file.length());
response.setHeader(Content-Length,Integer.toString((int)file.length()));
try {
out = response.getWriter();
// transfer the file byte-by-byte to the response object
File fileToDownload = new File(c:\video.zzz);
FileInputStream fileInputStream = newFileInputStream(fileToDownload);
int i;
while ((i=fileInputStream.read())!=-1)
{
out.write(i);
}
fileInputStream.close();
out.close();
}catch(Exception e) // file IO errors
{
e.printStackTrace();
}
Thanks,
Terry
Re: IE6 and download problem using tomcat java servlet
IE feels the need to cache the content before saving it to the desired
location. You probably have some headers in the response designed to
stop caching. You could comment in the RequestDumperValve to confirm this.
Add to your code:
response.setHeader(Pragma, public);
We saw similar problems for downloads from urls within our
security-constraint. They went away when we added this header.
