Hi experts,

you can just create a link to the file and browser will download it...

<a href="yourfile">Filename</a>

I have tried the code in the url

System.out.println("My file is:111111111111111111"+request.getParameter("file"));

String filename = request.getParameter("file");
String original_file = "/CourseFiles"+filename;

File f = new File(filename);
int length = 0;
ServletOutputStream op = response.getOutputStream();
ServletContext context = getServletConfig().getServletContext();
String mimetype = context.getMimeType( filename );

response.setContentType( (mimetype != null) ? mimetype : "application/octet-stream" );
response.setContentLength( (int)f.length() );
response.setHeader( "Content-Disposition", "attachement; filename=\"" + original_file+ "\"" );
byte[] bbuf = new byte[1000];
DataInputStream in = new DataInputStream(new FileInputStream(f));

while ((in != null) && ((length = in.read(bbuf)) != -1))
{
op.write(bbuf,0,length);
}

in.close();
op.flush();
op.close();

but I got this Exception 1.mp3 (The system cannot find the file specified)

the file I want to download it is mps file audio

it works fine in firefox, but not in IE7?

help plz? :)

Kuldeepchaturvedi

what error you are getting??

the quicktime plugin in the IE7 shows question mark image

Kuldeepchaturvedi

instead of opening up directly to quicktime, save to the disc and then run it with quicktime to see if the file is coming down correctly

Mayank S

Then the quicktime plugin is not properly configured with IE.

but when I open the url of mp3 in IE, quicktime plays the file.

>> response.setHeader( "Content-Disposition", "attachement; filename=\"" + original_file+ "\"" );

attach'E'ment with an extra E in between or attachment? I guess that is the issue. One of the versions of IE had this bug, not sure which one.
