Re: Streaming pdf document fails

[Christoph Meier]

I never used >>Content-disposition<<, yet. But it worked.
What is the "Content-disposition" for? to let the client sto store the 
PDF under the name which is after "filename="? ...



This is what tcptrace tells me is being sent back to the browser

HTTP/1.1 200 OK
Pragma: No-cache
Cache-Control: no-cache
Expires: Thu, 01 Jan 1970 00:00:00 GMT
Content-disposition: attachment; filename=N77-NTSP-E-70-0203.pdf
Content-Type: application/pdf
Content-Length: 443928
Date: Tue, 11 May 2004 19:29:37 GMT
Server: Apache-Coyote/1.1
If I remove the Content-disposition then the PDF opens in the browser ok,
but that is not what I want.
Secondly Mozilla still asks for the file twice and gets it, but only
displays one of them.

As far as i remeber, IE wants to know the content-length to show a PDF. =>
put the appopriate content-length into your Response-Header, ensure 
to have set the right content-type and i would expect that the 
PDF-stream should work then for IE, too.

I have a problem that just came up.  I have PDF documents located out 
side of my webapps directory. When the user wants one they go to my 
servlet which streams it back. This use to work just fine, but now is 
broke.

In IE I get Error opening document on TC4.1.30 and unable to open this 
Internet site in TC 5.0.19

Mozilla 1.6 does not have a problem opening the file.

What is odd is that Mozilla seems to request the servlet twice from one 
click, the first tends to throw this
ClientAbortException:  java.net.SocketException: Software caused 
connection

Is there anything wrong with what I am doing?
    response.setContentType("application/pdf");
    response.setDateHeader("Expires", 0);
// open pdf outside of browser
    response.addHeader("Content-disposition", "attachment; filename=" 
+ ntspNo + ".pdf");
    response.setContentLength((int)f.length());
    java.io.OutputStream out = response.getOutputStream(); // f is 
the pdf on the file system and it does exist
    java.io.FileInputStream in = new java.io.FileInputStream(f);
    int size = 0;
    byte[] buffer = new byte[8192];
    while( (size = in.read(buffer, 0, buffer.length)) != -1)
    {
      out.write(buffer, 0, size);
    }
    in.close();
    out.close();

Thanks
