 What do you mean you're trying to "attach" it?  Do you want the
PDF to come up in the user's browser window for viewing?  If so, just
put the PDF in a static file and redirect the user to it.  If you want
to force the user's browser to pop up the "Save As..." dialog, keep
reading:

 The code below looks basically right, comparing it to my notes
from when I wrote a servlet a few years ago to force a download.

 I don't recall any issue with the browser trying to download the
jsp.  There is an issue that the browser will assume the data file
being sent back is named the same as the page the browser requested.
The browser asks for "foo.jsp" and the server sends it a bunch of
binary data, it's going to naturally assume that data belongs in a
file named "foo.jsp".  You need to look at setting a
Content-Disposition header to set the filename, i.e.:

response.setHeader ("Content-Disposition", "attachment;  
filename=\"yourfilename.pdf\"");

 If that doesn't help, you might want to take a look at the
generated servlet code for this (i.e. use the -keepgenerated option
for your JSP compiler) and see if anything's tripping up the process
by sending extraneous data or headers back before your code gets to
setting headers and sending the binary data.

attachment in jsp

2002-12-24 Thread Venkat Muthusamy

Hi all,
I am trying to attach a pdf document in JSP.

Whenever I access the jsp I am getting error in first time. After that it is working 
fine . Any idea.

While open the url when firsttime it is saying (you are downloading *.jsp) in file 
save popup and gives error.After that it shows (you are downloading *.pdf)Then it 
opens the pdf.
Is there a way to suppress this error or am i doing something wrong in the code?
Any idea to attach a pdf using jsp is also welcome.
thanks
Venkat M

The code is as follows.

<%@ page import="java.io.*" %>
<%

BufferedInputStream bis = null;
   BufferedOutputStream bos = null;


 try {
   response.setContentType("application/pdf");
   response.setHeader("Content-disposition", "attachment; filename=" + 
"JspSyntax.pdf");

  String fileURL = "C:///jspsyntax.pdf";

   OutputStream outp = response.getOutputStream();
   FileInputStream is = new FileInputStream(fileURL);
   // Use Buffered Stream for reading/writing.
bis = new BufferedInputStream(is);
   bos = new BufferedOutputStream(outp);

   byte[] buff = new byte[2048];
   int bytesRead;

   // Simple read/write loop.
   while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
bos.write(buff, 0, bytesRead);
   }
  } catch (java.net.MalformedURLException e) {
   System.out.println("MalformedURLException.");
   e.printStackTrace();
  } catch (final IOException e) {
   e.printStackTrace();
   System.out.println("IOException.");
   //throw e;
  } finally {

   if (bis != null)
bis.close();
   if (bos != null)
bos.close();
  }
