exportReportToPdfStream - how to set filename
2002-11-12 09:51

Is there a way to set the filename of the PDF that gets sent down the stream from within my servlet when using JasperExportManager.exportReportToPdfStream()? Currently it sets the filename to be a section of my URL. Is there somehting in the HTML specification or MIME type rules that allows one to define the filename the user sees when downloading?

There are headers for it but it will work or not depending on the browser and version. It's very unreliable.

You should set the response header the following way. This works for netscape and mozilla, for IE it appears that the field CONTENT-DISPOSITION is obsolete and kept for backward compatibility, maybe there is a patch for IE...

So if u don't want the pdf to be opened in the browser here is what u should do:

String filename = "whatever";

response.setContentType( "application/octet-stream" );
response.setHeader( "Content-Disposition", "attachment; filename=\"" + filename + ".pdf\";" );

if u want the pdf to be opened directly into the browser just change the mime type:
response.setContentType( "application/pdf" );
response.setHeader( "Content-Disposition", "attachment; filename=\"" + filename + ".pdf\";" );

If it doesn't work in IE , try to set the content length :

byte[] bytes = JasperRunManager.runReportToPdf( "myreport.jasper", map, conn );

response.setContentLength( bytes.length );

ServletOutputStream out = response.getOutputStream();

out.write( bytes, 0, bytes.length );

Good Luck
