Set filename of the Pdf that is streamed back to the browser

I have a Java webapp creating a pdf and streaming it back to the browser.

 byte[] pdf = report.exportPdfToArray(user);
response.setContentType("application/pdf");
response.setHeader("content-disposition", "inline; filename=\"My.pdf\"");
outStream = response.getOutputStream();
outStream.write(pdf);
outStream.flush();
outStream.close();

The report is executed and it is sent back to the browser, but I can not control the name of the file even though I set the content-disposition. I am using Jboss 4.2.1. Do you know what am I missing?

EDIT: So is there any way to set the filename when the content-disposition is inline?

It's weird but it can be useful for someone(maybe someone can tell what is wrong with it):

When I set two headers like:

response.addHeader("content-length", String.valueOf(((FileInputStream) is).getChannel().size()));
response.addHeader("Content-disposition", "attachment; filename=\"MyFileName.doc\"");

It doesn't work. But when I change the order it works as expected:

response.addHeader("Content-disposition", "attachment; filename=\"MyFileName.doc\"");
response.addHeader("content-length", String.valueOf(((FileInputStream) is).getChannel().size()));

I have tried a solution in java and it worked.

response.setHeader("Content-Disposition","inline; filename=\"MyFile.pdf\"");
response.setContentType("application/pdf; name=\"MyFile.pdf\"");
response.getOutputStream().write(pdfAsBytesArray);

There is workaround to do so. We can use iframe where iframe will open in html page, iframe will hold the pdf report whereas the html page is independent of iframe. We can edit the title of html page that holds iframe.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form" %> 
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
    <head>
        <title>${reportName}</title>
    </head>
    <body>
        <iframe src="/fcWeb/ReportPDFServlet" width="100%" height="100%"></iframe> 
    </body>
</html>

MSIE will use the last part of the path info of the request URL (the part after the last /) as the default filename of the Save As action. It ignores the filename attribute of the Content-Disposition header altogether. All other browsers treat that header properly.

You need to change the URL pattern of your PDF servlet to a path mapping. I.e. do not use /pdf with http://example.com/context/pdf, but rather use /pdf/* with http://example.com/context/pdf/report.pdf. This way MSIE will use "report.pdf" instead of "pdf" as the default filename for the Save As action.
